Trade Glossary

A multi-wall paperboard drum, typically 50 to 200 litres capacity, used for the transport of solid chemicals, powders, granules, and crystals. UN-coded 1G when packing-group certified, with steel chimes top and bottom, often a metal lock-ring closure on the lid. Fibre drums are the dominant low-cost packaging for non-corrosive solid cargoes and are not designed to hold liquids.

A blow-moulded high-density polyethylene drum, typically 200 to 220 litres capacity, used for the transport of corrosive and aqueous chemical liquids. UN-coded 1H1 (closed-head, non-removable lid) for liquids and 1H2 (open-head, removable lid) for solids and viscous liquids. The default packaging for caustic soda solutions, hydrochloric acid, sodium hypochlorite, and most aqueous corrosive cargoes that would attack a steel drum.

The 20-foot ISO general-purpose intermodal container, the smallest of the standard ocean shipping container sizes. Internal dimensions approximately 5.9 m × 2.35 m × 2.39 m; payload capacity 28 MT (28,000 kg); volume capacity ~33 cubic metres. The unit measure (TEU, Twenty-foot Equivalent Unit) for container shipping statistics. Standard for chemical drum and IBC cargo at parcel scale.

The 40-foot ISO general-purpose intermodal container, twice the length of a 20-foot container but with the same width and height. Internal dimensions approximately 12.0 m × 2.35 m × 2.39 m; payload capacity 28-30 MT; volume capacity ~67 cubic metres. Counted as 2 TEU. Standard for chemical cargo at scale where the additional volume fits more drums, IBCs, or pallets without exceeding the weight limit.

The 40-foot ISO intermodal container with 2.896 m external height, approximately 30 cm taller than the standard 40'GP. Internal volume capacity is approximately 76 cubic metres versus 67 m³ for the standard 40-foot. Payload capacity remains around 28-30 MT, identical to 40'GP. The HC variant is the dominant container format on most container carriers' trans-Pacific and trans-Atlantic services.

A statistical sampling standard (ISO 2859-1) that defines the maximum percentage of defective units in a batch that the buyer will accept. AQL specifies the inspection sample size and the accept/reject thresholds based on batch size, inspection level, and the agreed AQL percentage.

Additional import duty imposed by a destination country on goods sold below fair market value (dumped) by a specific exporter or country of origin. Applied at the producer level, different rates for different Chinese factories, sometimes 0 percent for cooperating producers and 100+ percent for non-cooperating ones.

The combined US trade-remedy regime under which the Department of Commerce calculates antidumping and countervailing duties on imports of specific products from specific countries, and US Customs and Border Protection enforces the cash-deposit and final-duty assessment at entry. AD/CVD orders run on multi-year cycles, typically 5 years between sunset reviews, and produce per-importer cash-deposit rates that can change at every administrative review.

Australian regulatory scheme for industrial chemicals. Replaced NICNAS in July 2020. Categorises chemical introductions by risk and assigns annual reporting obligations to importers and manufacturers.

A Chinese commercial paper instrument where a bank accepts (guarantees) payment of a fixed amount on a fixed future date in exchange for a discount applied at issuance. BAB settles approximately 40% of Chinese B2B commerce. The instrument is opaque to non-Chinese-reading buyers but is the routine internal payment mode within Chinese chemical supply chains and a recurring lever in Sourzi-mediated payment routing for foreign buyers.

A bank's written commitment to pay a beneficiary on demand if the principal (the bank's customer) fails to perform an underlying obligation. Bank guarantees take many forms, payment guarantees, performance bonds, advance payment guarantees, bid bonds, retention guarantees. In China-international trade, bank guarantees are commonly used to back-stop performance obligations on capital-equipment and infrastructure contracts and as alternatives to letters of credit on smaller commodity transactions.

An alphanumeric identifier assigned by the manufacturer to a specific production run of a chemical product. The batch number (also called lot number) ties every drum, IBC, or container in the shipment back to the specific production conditions, raw material inputs, and quality control results recorded for that batch. Batch traceability is mandatory under most quality systems and is the foundation of any product-recall procedure. The terms 'batch' and 'lot' are used interchangeably in chemical manufacturing, with regional preferences, 'batch' is more common in Europe and Asia, 'lot' in the US.

The carrier-issued document that serves as receipt for the cargo, evidence of the contract of carriage, and document of title. Whoever holds the original B/L controls the cargo. Required for the destination port to release the container to the consignee.

A warehouse authorised by customs where imported goods can be stored without payment of import duties until the goods are withdrawn for domestic consumption. Duties are deferred, and in some cases avoided entirely, when the goods are subsequently re-exported from the bonded warehouse.

A surcharge added to ocean freight rates to compensate carriers for fluctuations in the cost of bunker fuel. BAF is recalculated periodically (monthly or quarterly) and varies by trade lane based on the carrier's fuel-consumption profile and the prevailing fuel price. The 2020 IMO global sulphur cap (0.5%) introduced higher-cost low-sulphur fuel oil (LSFO) and added a Low Sulphur Surcharge (LSS) layer on top of base BAF. Together with GRI, peak-season surcharges, and port-congestion surcharges, BAF makes the headline freight rate only part of the actual freight cost.

The Indian national standards body and the gatekeeper for mandatory product certification on imports into India. BIS administers the ISI Mark, the BIS Compulsory Registration Scheme (CRS), and product-specific mandatory standards. For chemical importers, BIS sets the Indian Standard specifications and the certification process that an Indian buyer requires before customs clearance for many regulated chemical commodities.

Third-party testing, inspection, and certification body. One of the three major TIC firms operating in China alongside SGS and Intertek. Provides pre-shipment inspection, factory audit, and laboratory testing services equivalent in scope to SGS.

The de-facto tiering of Chinese commercial banks based on size, regulatory standing, and international acceptance. Tier 1 is the Big Four state-owned commercial banks (ICBC, China Construction Bank, Agricultural Bank of China, Bank of China) plus Bank of Communications. Tier 2 is the joint-stock commercial banks (China Merchants Bank, Industrial Bank, Ping An, etc.). Tier 3 is the city commercial banks. Tier 4 is rural and smaller banks. For chemical buyers, the supplier's bank tier determines the credibility of bank-acceptance bills, the speed of cross-border settlement, and the acceptability of bank-issued instruments to the buyer's bank.

Multimodal Incoterm under which the seller arranges and pays for transport and insurance to the named destination. Risk transfers to the buyer when the cargo is handed to the first carrier in the country of origin, not at destination.

Multimodal Incoterm under which the seller arranges and pays for transport to the named destination. Risk transfers to the buyer when the cargo is handed to the first carrier in the country of origin. Insurance is the buyer's obligation.

The unique numerical identifier assigned by the Chemical Abstracts Service to every chemical substance described in the open scientific literature. Format is up to ten digits split into three hyphenated groups (e.g. 1310-73-2 for sodium hydroxide). The CAS Registry is the world's largest authoritative substance database with over 200 million entries. The CAS number is the lingua franca of chemical commerce, regulation, and procurement.

Conformity marking required on certain products sold in the European Economic Area, indicating the manufacturer has assessed the product against the relevant EU directives or regulations and the product meets EU safety, health, and environmental requirements. CE marking is largely product-category specific and does not apply to most bulk industrial chemicals.

A document issued by the manufacturer (or by an accredited third-party lab) certifying that a specific batch of a chemical or material meets the agreed specification. Lists tested parameters, results, the test methods used, and a batch number that ties back to production.

Document attesting that a product, batch, or shipment conforms to a specified standard, specification, or regulatory requirement. Issued by the manufacturer, a third-party certification body, or a destination-country pre-shipment inspection scheme. Distinct from the CE Declaration of Conformity, the COA, and the Certificate of Origin.

Document certifying the country in which the goods were produced or substantially transformed. Issued by an authorised body in the exporting country, used at destination customs to determine tariff treatment, including any preferential rate under a free trade agreement.

A four-year reporting cycle under TSCA Section 8(a) requiring US manufacturers and importers to report production and import volumes for chemicals on the TSCA Inventory above specified thresholds. The 2024 CDR submission period covered reporting years 2020-2023.

The Chinese inspection and quarantine regime that governs the entry and exit of goods, plants, animals, and people across Chinese borders. Originally administered by AQSIQ (the State Administration of Quality Supervision, Inspection and Quarantine), the CIQ functions were absorbed into the General Administration of Customs (GACC) in the 2018 reforms. CIQ inspection certificates are still issued under the CIQ brand for chemical, food, agricultural, and certain industrial cargoes.

Bilateral free trade agreement between China and Australia, in force since December 2015. Eliminates or reduces import duties on most goods traded between the two countries, including the majority of industrial chemicals, subject to rules of origin compliance.

EU Regulation (EC) No 1272/2008 implementing GHS in the European Union. Sets the classification criteria, labelling rules (pictograms, signal words, hazard statements), and packaging requirements for chemical substances and mixtures placed on the EU market. Mandatory for all substances and mixtures supplied in the EU and EEA.

CNY is the Chinese yuan as traded inside mainland China under the People's Bank of China (PBOC) regime; CNH is the offshore yuan traded primarily in Hong Kong, Singapore, and London. The two trade at slightly different rates with a typical spread of 50-200 basis points. PBOC sets a daily mid-point fix (the USD-CNY central parity) at 9:15 Beijing time around which onshore CNY trades within a ±2% band; CNH trades freely without the band. For Chinese chemical importers, the CNY/CNH spread and the daily fix are the two FX inputs that determine settlement cost.

The final invoice issued by the seller at shipment, replacing the proforma invoice with as-shipped quantities and values. Used by destination customs as the primary document for valuation and duty calculation. Required at every customs entry.

Incoterm under which the seller arranges and pays for sea freight to the named destination port. Risk transfers to the buyer once the cargo crosses the ship's rail at the load port. The buyer arranges marine insurance and absorbs all destination-side costs.

Incoterm under which the seller is responsible for the cost of the goods, marine insurance, and sea freight to the named destination port. Risk transfers from seller to buyer when the goods are loaded on board at the origin port, but cost responsibility extends to destination port arrival.

Additional import duty imposed by a destination country to offset government subsidies that benefit a foreign producer. For Chinese exports, CVD investigations target subsidies including preferential loans, tax exemptions, energy subsidies, raw-material price supports, and provincial industrial policies. Often imposed alongside anti-dumping duty.

The Chinese regulatory regime under which Chinese yuan (CNY) flows between mainland China and the offshore world for trade and investment purposes. Operated through the Cross-Border Interbank Payment System (CIPS) and supplemented by SWIFT, the regime allows CNY to be settled directly in trade transactions rather than requiring USD intermediation. Cross-border CNY settlement reduces FX cost, accelerates settlement, and is the principal mechanism by which the yuan has internationalised.

The Chinese export customs declaration form (报关单, baoguan dan) that the consignor or its appointed customs broker submits to the General Administration of Customs (GACC) for every export shipment leaving China. The declaration includes consignor and consignee details, HS code classification, customs value, weight and quantity, transport details, and supporting document references. It is the legal document that formally authorises the cargo to leave Chinese customs territory.

The valuation of imported goods used by customs authorities to assess duty, tax, and statistical reporting. The standard method under the WTO Customs Valuation Agreement is transaction value, the price actually paid or payable for the goods in the export sale, with prescribed adjustments. When transaction value is unavailable or unacceptable, customs falls back through five secondary methods in a fixed sequence. Customs value is the foundation of every duty calculation.

The IMDG hazard class for flammable liquids, substances with a flash point of 60 degrees Celsius or below. Covers solvents, alcohols, ketones, esters, fuels, and many industrial intermediates routinely shipped from Chinese chemical factories. Subject to packing group I, II, or III based on flash point and initial boiling point.

The IMDG hazard subclass for flammable solids, self-reactive substances, and solid desensitised explosives. Covers materials that ignite readily by friction or external heat, polymerising substances, and self-reactive substances that decompose with the release of heat. Subject to packing group I, II, or III based on burn rate and self-heating behaviour.

The IMDG hazard subclass for substances liable to spontaneous combustion. Covers pyrophoric substances that ignite within 5 minutes of contact with air, and self-heating substances that heat up in contact with air without external energy. Includes white phosphorus, certain metal alkyls, alkali-metal amalgams, and some activated catalysts.

The IMDG hazard subclass for substances dangerous when wet, substances that emit flammable gases on contact with water at a rate above the IMDG-defined threshold. Covers alkali and alkaline earth metals, metal hydrides, metal carbides, certain metal alkyls, and a number of inorganic salts. Subject to packing group I, II, or III based on gas-evolution rate.

The IMDG hazard subclass for oxidising substances, substances that release oxygen and can intensify the combustion of other materials. Covers nitrates, chlorates, perchlorates, peroxides, and certain inorganic salts. Subject to packing group I, II, or III based on test reactivity with combustible materials.

The IMDG hazard subclass for organic peroxides, substances containing the bivalent -O-O- structure that can be regarded as derivatives of hydrogen peroxide. Subject to thermally unstable decomposition that can be self-accelerating, requiring temperature control during transport for many entries. Used as polymerisation initiators, bleaching agents, and crosslinking chemistry across plastics manufacturing.

The IMDG hazard subclass for toxic substances, substances that can cause death, serious injury, or harm to human health if swallowed, inhaled, or absorbed through the skin. Covers cyanides, arsenic and mercury compounds, many pesticides, isocyanates, and a wide range of toxic intermediates routinely shipped from Chinese chemical factories.

The IMDG hazard subclass for infectious substances, substances known or reasonably expected to contain pathogens (microorganisms, viruses, prions, recombinant nucleic acids) capable of causing disease in humans or animals. Split into Category A (high pathogenicity, UN 2814 / UN 2900) and Category B (lower pathogenicity, UN 3373). Rare in industrial chemical sourcing but routine in pharmaceutical and biotech supply chains.

The IMDG hazard subclass for corrosive substances, substances that cause irreversible damage to skin, severely corrode metals, or both. Covers acids (sulphuric, hydrochloric, nitric, phosphoric), bases (sodium hydroxide, potassium hydroxide), and certain oxidising acids and salts. The single highest-volume DG class in Chinese chemical exports.

The IMDG hazard subclass for miscellaneous dangerous substances and articles. Covers materials that present a transport hazard but do not meet the criteria for any other class. Includes lithium batteries, asbestos, dry ice, environmentally hazardous substances, and elevated-temperature substances. The fastest-growing DG class in containerised trade due to the lithium-battery supply chain.

The Chinese provincial-level licence required to manufacture any substance on the Catalogue of Dangerous Chemicals (currently around 2,800 substances). Issued by the provincial Ministry of Ecology and Environment with cross-sign-off from MEM (Ministry of Emergency Management) and the local Work Safety bureau. Specifies the substances licensed, production capacity, technology, and safety case. Renewal typically every 3 years.

A signed shipper's document required for every dangerous-goods sea shipment, certifying that the cargo has been properly classified, packaged, marked, labelled, and is in the proper condition for transport. Issued under the IMDG Code on the IMO Multimodal Dangerous Goods Form.

Incoterm under which the seller delivers the goods to the named destination ready for unloading by the buyer. The seller carries all transport risk and cost up to that point but does not pay destination duties or arrange import customs.

Incoterm under which the seller is responsible for delivering the goods to the buyer's named destination, including all transport, customs clearance, duties, taxes, and unloading at destination. The most seller-heavy Incoterm, often misused in China-export quotes.

Charges levied by the carrier or terminal when a container remains at the port (loaded or empty) beyond the free time allowed. Calculated per container per day, escalating with the duration of the delay. Distinct from detention, which applies once the container leaves the port.

Charges levied by the carrier when a container is held outside the port (at the consignee's premises or anywhere off-terminal) beyond the free time allowed for unloading and return. Calculated per container per day after the free time expires.

An international trade payment mechanism where the seller's bank forwards shipping documents through the buyer's bank, which releases them to the buyer only on payment (D/P, Documents against Payment) or on acceptance of a future-dated draft (D/A, Documents against Acceptance). The instrument provides bank-mediated document handling without bank-side payment guarantee, cheaper than an LC, with more risk to the seller.

A cylindrical industrial packaging unit, typically 200 or 220 kilograms gross capacity, used for the transport of liquid and solid chemicals. Available in steel (UN 1A1, 1A2), HDPE (UN 1H1, 1H2), fibre (UN 1G), and lined or coated variants. The standard parcel-size packaging for chemical shipments where IBC scale is unjustified and drum-handling infrastructure is universally available.

Refund of import duties (including MFN, Section 301, anti-dumping, and countervailing duties) on goods that are subsequently exported, used in the manufacture of exported goods, or destroyed under customs supervision. A significant cost-recovery tool for importers who re-export or manufacture for export.

The Chinese government licence required for export of certain controlled commodities, dual-use items, strategic materials, and chemicals subject to international treaty obligations. Issued primarily by the Ministry of Commerce (MofCom) under various regulations, with cross-agency approval from the Ministry of Ecology and Environment (MEE) for chemical-specific cargoes. The export licence is the legal authorisation for the cargo to leave China and is referenced in the customs declaration.

The unique numerical identifier assigned to chemical substances on EU regulatory inventories, primarily EINECS (substances on the EU market before 1981), ELINCS (notified post-1981), and the NLP list (no-longer-polymers). Format is a seven-digit number split as three-three-one with hyphens (e.g. 215-185-5 for sodium hydroxide). The EC number is the EU's substance identifier; CAS is the global substance identifier.

A payment arrangement in which a third party holds funds on behalf of two transacting parties and releases them only when specified conditions are met. In China-international chemical trade, escrow is most commonly seen on B2B platforms (Alibaba Trade Assurance, Made-in-China Secure Trade) and on smaller transactions where neither party is willing to pre-pay or post-pay. Escrow is operationally simpler than a letter of credit but carries platform fees and platform-specific dispute mechanics.

Incoterm under which the seller's only obligation is to make the goods available for collection at their factory or warehouse. The buyer arranges and pays for everything else: loading, inland transport, export clearance, freight, insurance, and destination-side costs.

An IMDG provision allowing very small quantities of dangerous goods to ship under almost full exemption from regulatory requirements. Inner-packaging maximum is typically 1 mL to 30 mL for liquids or 1 g to 30 g for solids, with an outer-packaging cap of 1 kg gross. EQ shipments require minimal marking and no DG declaration. Used for laboratory samples, calibration standards, and very small quantity shipments where LQ is overkill.

A large flexible textile bag designed for the transport of bulk solid materials, typically holding 500 kg to 2,000 kg per bag. Standard format is woven polypropylene with built-in lifting loops. UN-certified versions (UN codes 13H1, 13H2, 13H3, 13H4) ship dangerous solid cargoes. Big bags are the dominant packaging for bulk solid chemicals, ammonium sulphate, urea, soda ash, citric acid, calcium chloride, at scale.

A structured inspection of a Chinese chemical factory by a buyer or independent third party covering production capacity, quality systems, regulatory compliance, environmental controls, and operational maturity. Factory audits are standard practice before placing first orders with a new supplier and at periodic intervals (annual or biennial) for established suppliers. A typical chemical-factory audit covers 30-80 specific evaluation points across six or seven domains and produces a written report scoring each area.

The official tax invoice issued through China's Golden Tax System for any commercial transaction in China. Two main forms: VAT-special-invoice (增值税专用发票) used by businesses to claim input VAT credits, and VAT-general-invoice (增值税普通发票) used for retail and non-VAT-credit transactions. The fapiao is the only invoice that satisfies Chinese tax law and supports VAT export rebate claims.

Incoterm under which the seller delivers the goods alongside the vessel at the named port of shipment, ready for loading. Risk and cost transfer to the buyer at that point. The buyer arranges loading on board, sea freight, insurance, and all destination-side costs.

Incoterm under which the seller delivers the goods to the buyer's nominated carrier at a named place, either the seller's premises (FCA factory) or another named location. Seller handles export clearance. Modern alternative to EXW that fixes the export-clearance gap.

Incoterm under which the seller delivers the goods on board the vessel at the named port of shipment. Risk and cost transfer to the buyer once the cargo crosses the ship's rail. The buyer arranges and pays for sea freight, marine insurance, and all destination-side costs.

The number of calendar days a container can sit at a port or terminal without incurring demurrage or detention charges. Carriers grant free time at the port of discharge (typically 3-7 days for standard cargo, longer for project cargo) and at the inland depot (detention free time). Once free time expires, the demurrage clock starts and rates escalate. Free time is the buffer between vessel arrival and the moment storage charges begin to accrue.

The preferential tariff rate that applies to imports from a country with which the United States (or any importing country) has a free trade agreement in force. FTA tariffs are typically zero or substantially below the MFN rate but are subject to product-specific rules of origin. The FTA preference is claimed at entry by listing the relevant special program indicator and supporting the claim with a certificate of origin.

FCL is a shipment that fills (or is contracted to fill) a complete container, 20-foot, 40-foot, or 40-foot high cube. LCL is a shipment that does not fill a container and is consolidated with other shippers' cargo into a shared container by a freight forwarder.

The Chinese national standards classification system. GB (国标, guobiao) standards are mandatory; GB/T standards are recommended. The GB 30000 series implements GHS chemical hazard classification in China; the GB 12268 series covers dangerous goods transport classification; the GB 50016 series covers fire-safety design. GB classification is the Chinese-domestic counterpart of UN GHS, IMDG, and the various international standards regimes.

The Chinese national standard governing the format and content of Safety Data Sheets for chemical products. Issued by the Standardisation Administration of China (SAC), GB/T 17519 specifies the 16-section structure aligned with GHS for chemicals manufactured, sold, or shipped within China. The latest revision (GB/T 17519-2013) is the active standard for SDS authoring on Chinese-language documents.

The Chinese government ministry responsible for customs administration, import and export licensing, customs valuation, classification, and trade-data publication. Reports to the State Council. The publisher of monthly Chinese trade statistics, the issuer of preferential Certificates of Origin under FTAs, and the regulator of all chemical exports through Chinese ports.

A US trade programme that grants duty-free access for thousands of products from designated developing-country beneficiaries. Authorised under the Trade Act of 1974, GSP is renewed by Congress periodically and has lapsed several times. China is not a GSP beneficiary, so GSP does not apply to Chinese imports, but importers sourcing from Vietnam, Thailand, Indonesia, India, and other GSP countries should know how the programme interacts with chemical sourcing decisions.

The nine standardised hazard symbols used on chemical labels and SDSs under the UN Globally Harmonized System. Each pictogram is a red-bordered diamond on white background with a black symbol indicating a specific hazard family. Used worldwide in EU CLP, US OSHA HCS, China GB/T 17519, and other jurisdiction-specific GHS implementations.

The United Nations system for classifying and labelling chemicals based on physical, health, and environmental hazards. GHS provides standardised hazard classes, label elements (pictograms, signal words, H- and P-codes), and SDS structure adopted in jurisdiction-specific implementations including EU CLP, US OSHA HCS, China GB/T 17519, and Australia HCIS.

The Chinese national value-added tax (VAT) administration platform run by the State Taxation Administration. The Golden Tax System (currently in its Phase IV deployment) controls the issuance, validation, and reconciliation of VAT invoices (fapiao) across every Chinese enterprise. Every commercial transaction in China that produces a fapiao runs through the Golden Tax System; mismatches between fapiao and tax filings produce immediate enforcement attention.

A six-digit international product classification code used by customs authorities worldwide to identify goods, assess duties, and apply trade controls. Countries extend the six-digit base with additional digits for tariff and statistical purposes (10-digit HTS in the US, 8-digit CN code in the EU, 10-digit AHECC in Australia).

The US implementation of the global Harmonized System for product classification at the border. HTS codes have 10 digits, the first 6 match international HS, the next 2 are US-specific tariff lines, and the final 2 are statistical suffixes. The HTS classification determines tariff rate, eligibility for trade preferences, and applicability of any anti-dumping orders.

Standardised text describing the nature of a chemical hazard, identified by an H-code under the UN Globally Harmonized System. Format is the letter H followed by three digits where the first digit indicates hazard family (H2xx physical, H3xx health, H4xx environmental). Required on chemical labels and SDSs in adopted GHS implementations including EU CLP, US OSHA HCS, and China GB/T 17519.

The full enumerated list of GHS Hazard Statements (H-codes), each describing the nature of a chemical hazard. The list contains physical hazard statements (H200-H290), health hazard statements (H300-H373), and environmental hazard statements (H400-H420), plus EU-specific supplementary statements (EUH-codes). H-codes are the standardised text that appears on every GHS-aligned SDS and container label.

The HS chapter covering inorganic chemicals and organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements, or of isotopes. Covers the bulk of the inorganic-chemical export trade from China, caustic soda, sulphuric acid, soda ash, hydrogen peroxide, hydrochloric acid, titanium dioxide, and most metal oxides and salts. The single most volume-significant HS chapter for chemical importers.

The HS chapter covering organic chemicals, defined organic compounds with specified chemical constitution. Covers methanol, acetone, aromatics (benzene, toluene, xylene), alcohols, ketones, ethers, esters, organic acids, amines, and a vast range of fine-chemical and pharmaceutical intermediates. The chapter most affected by anti-dumping orders against Chinese-origin imports.

The HS chapter covering miscellaneous chemical products, products of the chemical industry that do not fit cleanly into Chapters 28 (inorganic chemicals), 29 (organic chemicals), or other specialised chemical chapters. Covers prepared additives, catalysts, lubricant additives, glues, mould-release agents, anti-knock preparations, fuel additives, biodiesel, surface-active agents, sorbents, and dozens of other functional chemical formulations. Chapter 38 is the catch-all for chemical products defined by use rather than by molecular composition.

The International Maritime Solid Bulk Cargoes Code, the IMO regulation governing the safe transport of solid bulk cargoes by sea. Classifies cargoes into Group A (cargoes that may liquefy), Group B (cargoes possessing chemical hazards), and Group C (neither). Mandatory under SOLAS for all solid bulk cargoes carried in dedicated bulk carrier ships.

The 2020 revision of the International Chamber of Commerce Incoterms rules. Eleven defined trade terms covering the obligations of buyer and seller for delivery, risk transfer, cost, and documentation. The version in force for most international trade contracts written after January 2020.

A reusable industrial container designed for the transport and storage of liquids and bulk solids, typically holding 1,000 litres (1 cubic metre). The standard IBC is a steel-cage outer frame with a translucent HDPE inner bottle on a wooden, plastic, or metal pallet. UN-certified IBCs (codes 31HA1, 31HA2, etc.) ship dangerous goods. Used widely in chemical sourcing for parcels too small for an ISO tank but too large for drums.

An open, non-proprietary string identifier for chemical substances developed by IUPAC and the InChI Trust. Generated algorithmically from the molecular structure, the InChI is unique per substance and machine-readable. The compact InChIKey (a 27-character hash) is the form most commonly used in databases. Free, deterministic, and structurally unambiguous, the InChI is the GEO-friendly identifier for chemical content because AI engines can resolve any InChIKey to a single substance with no ambiguity.

The international rulebook for shipping dangerous goods by sea. Defines classification, packaging, labelling, documentation, and segregation requirements for hazardous cargo on container vessels.

The Chinese national chemical inventory listing substances legally manufactured, imported, used, or sold in China before 2003. A substance not on IECSC requires a New Chemical Substance Notification (NCSN) under MEE Order 12 before it can be manufactured or imported into China. Functionally similar to TSCA in the US and REACH in the EU but with distinct procedural requirements.

A stainless-steel or alloy-steel cylindrical pressure vessel mounted in a 20-foot ISO container frame, designed for the transport of bulk liquids and gases. Capacities typically 18-26 cubic metres (16-25 MT depending on cargo density). UN portable tank instructions cover four families: T1 to T22 for liquids and solids of Classes 1 and 3 to 9, T23 for Class 4.1 self-reactive substances and Class 5.2 organic peroxides, T50 for non-refrigerated liquefied gases, and T75 for cryogenic liquefied gases. ISO tanks carry the bulk of the world's hazardous liquid chemical trade and compete with parcel tankers at different scales.

The systematic chemical name assigned to a substance under the nomenclature rules of the International Union of Pure and Applied Chemistry. Each IUPAC name is generated from the molecular structure following published nomenclature rules and is, in principle, unambiguous. The IUPAC name is the universal scientific reference name for the substance and is the form most commonly used in primary chemical literature, patents, and regulatory dossiers.

South Korean Act on the Registration and Evaluation of Chemicals, the Korean equivalent of EU REACH. Requires registration of substances manufactured in or imported into Korea above 1 tonne per year. Administered by the Ministry of Environment through NIER. Includes phase-in registration tiers, joint submission requirements, and a designated 'Only Representative' mechanism for non-Korean manufacturers.

The period of time a charterparty agreement allows for the loading or discharge of cargo at a port, after which demurrage begins to accrue. Laytime starts when a Notice of Readiness (NOR) is tendered and accepted, and is recorded in the Statement of Facts (SoF) signed by ship's master and shore agent. Lay days are central to bulk-vessel chartering (tankers, dry-bulk carriers, project-cargo ships) where the charterer commits to a specific load or discharge rate. Container shipping uses free time + demurrage rather than laytime, but the underlying concept is the same.

A bank instrument that guarantees payment to the seller against presentation of compliant shipping documents. The buyer's bank issues the L/C; the seller's bank verifies the documents and releases payment. Used for high-value first orders, new factory relationships, or where the buyer's market norms require it.

An IMDG provision allowing dangerous goods packed in small inner packagings to ship under reduced regulatory requirements. Each substance has a maximum LQ inner-packaging size (typically 0.5 to 5 litres or kilograms). LQ packages are exempt from many DG documentation, marking, and segregation rules but carry the distinctive black-and-white LQ diamond mark.

A steel drum with an internal corrosion-resistant lining, used for cargoes that require steel structural strength but would attack bare steel. Common linings include phenolic epoxy, baked phenolic, polyethylene insert, and PTFE coating. Lined drums extend the cargo-compatibility envelope of the standard 1A1 steel drum to cover concentrated acids, peroxides, and food-grade products that need a non-reactive contact surface.

A designation under MARPOL Annex III for substances that are harmful to the marine environment if released. Marine-pollutant cargo carries additional packaging marking, stowage restrictions, and documentation requirements regardless of the substance's other IMDG hazard class. Common chemical exports including many pesticide active ingredients, certain solvents, copper compounds, and surfactants are designated.

The Chinese government authority responsible for maritime safety, ship registration, port-state control, and the regulation of dangerous goods carried by sea on Chinese-flagged vessels and in Chinese ports. Reports to the Ministry of Transport. MSA China issues the Dangerous Goods Container Packing Certificate (危险品集装箱适装证明) that every DG export shipment from China must carry, alongside other operational permits for chemical cargo movement.

The IMO regime governing pollution by noxious liquid substances carried in bulk at sea. Classifies bulk liquid chemicals into categories X, Y, Z, and OS based on environmental hazard, and prescribes ship type, tank cleaning, and discharge restrictions. Applies to ISO-tank, parcel-tanker, and chemical-tanker shipments, not to packaged cargo.

A document that summarises a chemical's hazards, handling requirements, first-aid measures, and emergency response information. Required for every dangerous-goods shipment and most non-DG industrial chemicals. Modern usage is shifting from MSDS to SDS under the GHS standard.

The smallest order a factory will accept and produce. Set by the manufacturer based on production economics, minimum efficient batch size, set-up costs, and packaging line constraints. For Chinese chemical exports, MOQ is typically expressed in metric tonnes, IBC count, drum count, or ISO tank load.

The Chinese government ministry responsible for environmental policy, chemical substance management, pollution control, and the IECSC inventory and New Chemical Substance Notification regime. Reports to the State Council. Equivalent in scope to the EU Commission DG Environment plus ECHA, or the US EPA. The single most influential regulator on Chinese chemical production capacity and chemical export eligibility.

An international treaty that phases out the production and consumption of ozone-depleting substances (ODS). Adopted in 1987 and entered into force in 1989, the protocol controls 96 listed substances across CFCs, halons, HCFCs, methyl bromide, and (under the Kigali Amendment) HFCs. Universal ratification has been achieved, every UN member state is a party. The Montreal Protocol is the most successful environmental treaty in history.

The standard tariff rate a WTO member country applies to imports from all other WTO members in the absence of a preferential trade agreement. The base rate before any anti-dumping, countervailing, Section 301, or FTA preferential rate is layered on. For Chinese-origin chemicals into the US, EU, Australia, and most other markets, MFN is the starting point for landed-cost calculation.

The geographical location specified after an Incoterm in a contract of sale. The named place fixes the exact point at which risk, cost, or both transfer between seller and buyer. Without it, an Incoterm is incomplete and unenforceable.

Special-purpose Chinese bank accounts that allow foreign-resident entities to hold and transact in CNY or foreign currency under specific cross-border rules. NRA (Non-Resident Account) is the standard onshore non-resident account used outside the free trade zones. OSA (Offshore Account) is the offshore-Chinese-bank booking account. FTN (Free Trade Non-Resident Account) is the FTZ-based equivalent with broader convertibility rights. Together, these account types let international counterparties settle CNY and FX without going through full domestic Chinese banking residency.

A payment arrangement under which the seller ships and bills the buyer with payment due at a later agreed date, typically 30, 60, 90, or 120 days after the bill of lading or invoice date. Open account places the full payment risk on the seller. It is the cheapest payment method (no bank fees) and the most flexible, but it is appropriate only when the buyer's credit is verified and the seller has either credit insurance or sufficient capital to absorb a default.

The US workplace standard administered by the Occupational Safety and Health Administration that mandates how employers communicate chemical hazards to workers. Codified at 29 CFR 1910.1200, OSHA HCS aligns with UN GHS Rev. 7 and requires GHS-format Safety Data Sheets, GHS-aligned container labels, and a written workplace hazard communication programme. For Chinese chemical exporters to the US, OSHA HCS is the standard that the importing employer must satisfy and is what dictates the required SDS and label format.

Three-tier classification under the IMDG Code (and other transport regulations) indicating the relative severity of hazard within a dangerous-goods class. PG I is the most hazardous (great danger), PG II is medium danger, PG III is minor danger. Determines the required packaging strength and the regulatory burden of the shipment.

Document issued by the shipper detailing the contents, packaging, weights, and dimensions of every package in the shipment. Used by the carrier for stowage planning, by customs for entry verification, and by the buyer for receiving inspection.

The Port of Loading (POL) is the named port at which cargo is loaded onto the international vessel; the Port of Discharge (POD) is the named port at which the cargo is unloaded from the international vessel. Both are stated explicitly on the bill of lading and define the contractual scope of the carriage. POL determines origin THC, origin clearance, and the named-place anchor for FOB / CFR / CIF Incoterms; POD determines destination THC, free time, demurrage exposure, and final-mile logistics.

Standardised text describing the recommended action to minimise or prevent adverse effects from a chemical hazard, identified by a P-code under the UN Globally Harmonized System. Format is the letter P followed by three digits where the first digit indicates statement category (P1xx general, P2xx prevention, P3xx response, P4xx storage, P5xx disposal). Required on chemical labels in adopted GHS implementations.

The operational mechanism of the Rotterdam Convention. Each country party publishes a national decision (consent, refusal, or conditional consent) for every chemical on Annex III. Exporting parties communicate the decisions to their domestic exporters. A cargo of an Annex III chemical can only ship to a country that has published consent for that chemical.

A preliminary invoice issued by the seller before goods are produced or shipped. Confirms the agreed terms, substance, specification, quantity, unit price, total value, packaging, payment terms, Incoterm, port of loading, port of discharge, and serves as the contractual basis for the buyer's deposit payment.

The structured choice of where, how, and through which intermediaries a chemical buyer pays a Chinese supplier. Payment routing decisions encompass the currency (USD or CNY), the account structure (NRA, OSA, or domestic), the payment method (T/T, L/C, escrow, open account), the trade-finance instrument layered on top (Sinosure insurance, bank-acceptance bills), and the FX execution timing. For volume buyers, payment routing is a treasury function that captures 0.5-3% of total cargo cost in saved spread, fees, and timing arbitrage.

An insulated intermodal container with an integrated refrigeration unit, used for cargo requiring temperature control during transport. Standard sizes are 20-foot and 40-foot high-cube. Carriers code reefers as RF (general reefer) or 40'RH (40-foot reefer high cube). Reefer plug-in slots on vessel and at terminals are limited and command a hazmat-style premium of USD 2,000-5,000 per leg over a standard dry container.

EU chemical regulation requiring importers and manufacturers to register every substance manufactured or imported into the EU above 1 tonne per year. Registration is identity-based and dossier-based, not inventory-lookup-based, which makes it stricter than TSCA in the US.

The exact moment in a shipment at which the risk of loss or damage to the goods passes from seller to buyer. The risk transfer point is fixed by the chosen Incoterm and is often different from the point at which freight cost transfers.

An international treaty that operates a Prior Informed Consent (PIC) procedure for trade in certain hazardous chemicals and pesticides. Adopted in 1998 and entered into force in 2004, the convention currently lists 55 chemicals across pesticide, severely hazardous pesticide, and industrial categories. Parties to the convention must give explicit prior consent before any listed chemical is exported into their territory.

The criteria used to determine the country of origin of a good for tariff and trade-defence purposes. Two main types: non-preferential rules (used to apply MFN tariff, anti-dumping, and other measures) and preferential rules (used to qualify goods for FTA preferential tariffs). Different FTAs use different rules of origin tests, which is why a good qualifying for one FTA preference may not qualify for another.

The Chinese state-owned export credit insurance agency, providing credit insurance to Chinese exporters covering buyer non-payment, political risk, and certain commercial risks. Coverage signals creditworthiness, a Chinese supplier whose buyer is Sinosure-coverable has stronger commercial standing than one whose buyer is not. Sinosure exposure data is a recurring proxy for buyer risk in Chinese supplier evaluation.

A bill of exchange (draft) drawn by the seller on the buyer requiring payment immediately on presentation. The seller presents the draft along with shipping documents to the buyer's bank; the buyer's bank releases the documents to the buyer only on payment. A standard structure under documentary collection arrangements and a common payment mode in Chinese chemical trade for established buyer-seller relationships.

The 16-section document that communicates the hazards, handling, storage, and emergency response information for a chemical product. Required at destination customs for any classified hazardous chemical and at the buyer's site for worker safety. SDS is the GHS-aligned successor to the older MSDS format.

Additional tariffs imposed by the United States on Chinese-origin goods under Section 301 of the Trade Act of 1974. The current List 1, 2, 3, and 4A tariffs add 7.5 to 25 percent on top of the standard MFN duty rate, applied at HS-code level.

A pre-manufacture filing required under TSCA Section 5 when a US manufacturer or importer intends to introduce a new chemical substance not on the TSCA Inventory. The EPA has 90 days to review and may impose use restrictions, testing requirements, or outright prohibition.

The 9-by-9 IMDG matrix specifying how each dangerous goods class must be stowed in relation to each other class on a vessel. Codes range from '1' (away from) to '4' (separated longitudinally by an intervening complete compartment or hold) to 'X' (no general requirement, see specific entries). The reference any forwarder uses to confirm whether a mixed-DG shipment is stowable in the same container or vessel.

Independent third-party inspection conducted by SGS (Société Générale de Surveillance), or comparable bodies like Bureau Veritas and Intertek, at the factory before a chemical or industrial cargo is loaded for export. Verifies quantity, packaging, labelling, and conformity to the agreed specification.

The single word on a chemical label indicating the relative severity of the hazard under the UN Globally Harmonized System. Two signal words are defined: 'Danger' for the most severe hazard categories, 'Warning' for less severe categories. The signal word is language-translated for each destination market and appears in bold uppercase below the pictograms.

An open chemical notation that represents the structure of a molecule as an ASCII string. Developed in the late 1980s by David Weininger and now maintained as a public specification, SMILES uses letters for atoms, digits for ring closures, and a small set of symbols for bonds and stereochemistry. SMILES is human-readable, compact, and the de facto input format for cheminformatics software. A SMILES string converts losslessly to and from a chemical structure.

A bank-issued instrument under which the issuing bank promises to pay a beneficiary upon presentation of specified documents evidencing default by the bank's customer. SBLC functions as a payment guarantee rather than a primary payment mechanism, it pays only if the underlying transaction fails. Used in international chemical trade for performance guarantees, advance-payment guarantees, and as backstop credit support for ongoing supply contracts.

An international treaty that targets Persistent Organic Pollutants (POPs) for global elimination, restriction, or unintentional-release reduction. Adopted in 2001 and entered into force in 2004, the convention currently lists 34 POPs across three annexes. Annex A (elimination), Annex B (restriction), and Annex C (unintentional production). Unlike the Rotterdam Convention, Stockholm phases chemicals out of trade rather than enabling informed consent for trade.

A substance identified by ECHA under EU REACH Article 57 as having serious effects on human health or the environment. Once a substance is added to the SVHC Candidate List, immediate downstream-user notification obligations apply. Substances on the Candidate List can subsequently be moved to the REACH Authorisation List, requiring EU customers to obtain authorisation to use them.

The Integrated Tariff of the European Union, the EU customs tariff database with 10-digit codes built on the international 6-digit HS and the EU 8-digit Combined Nomenclature. TARIC integrates duty rates, anti-dumping orders, suspensions, quotas, restrictions, and trade-defence measures applicable to each tariff line for imports into the EU.

Document published by the manufacturer specifying the typical performance, physical, and chemical properties of a chemical product. Used by buyers for product selection and formulation. Distinct from the COA, which certifies actual values for a specific batch, and the SDS, which covers safety and handling.

Chemical grade designations indicating purity tier. Technical grade is the industrial-use grade, typically 90-99% pure with trace impurities acceptable for most industrial processing applications. Pure grade (also called reagent grade, ACS grade, or analytical grade) is 99.5%+ pure with controlled impurity profiles, used in laboratory analysis, electronics manufacturing, and pharmaceutical applications. Pharmaceutical and food grades are stricter still. The grade designation drives a 2-10x price differential and determines which manufacturing applications the chemical is suitable for.

International wire transfer between bank accounts, the dominant payment method for Chinese chemical exports. Standard terms are 30 percent T/T advance against the proforma invoice and 70 percent T/T against the bill of lading copy before vessel sailing.

Charges levied by container terminals for the loading, unloading, and handling of containers at the port. THC is charged at both ends, at the origin port (origin THC, billed to the consignor on FOB / FCA shipments) and at the destination port (destination THC, billed to the consignee on CIF / CFR / FOB shipments). THC rates vary by terminal, container size, and DG/non-DG status, typically running USD 100-400 per 20'GP and USD 150-550 per 40'GP.

An independent inspection of cargo by a non-affiliated firm, typically conducted before the cargo ships from China to verify quantity, quality, packaging, marking, and document conformance against the contract. Pre-shipment inspection (PSI) is the most common form. The dominant providers are SGS, Bureau Veritas, TUV Rheinland, TUV SUD, Intertek, and Cotecna. A typical pre-shipment inspection costs USD 300-1,500 per shipment depending on cargo complexity, with the report delivered before vessel loading.

US federal law that gives the EPA authority to track and restrict the manufacture, import, processing, distribution, and disposal of industrial chemicals.

The transfer of cargo from one vessel to another at an intermediate port en route to the final destination. Transhipment lets carriers consolidate cargo at hub ports (Singapore, Busan, Tanjung Pelepas, Algeciras) and run smaller feeder vessels to spoke ports. Transhipment routes are typically 5-15 days slower than direct vessel routes and add at least one extra cargo-handling event, but rates are usually 10-30% lower. Direct vessel routing is the alternative, a single vessel sails POL to POD without offloading the cargo.

A four-digit identifier assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods to identify a hazardous substance for international transport. Required on the DG Declaration, the package marking, the placards on the container, and Section 14 of the MSDS.

A letter of credit under which payment is deferred to a specified date after presentation of compliant documents, typically 30, 60, 90, 120, or 180 days. Also called a deferred-payment L/C or term L/C. The seller receives a bank's payment commitment at presentation but receives funds at the maturity date. The buyer obtains a financing window, the cargo is in hand and may have been resold before the L/C matures. Usance L/Cs are common on bulk commodity trades from China where buyers need working-capital flexibility.

The Chinese government refund of value-added tax paid on inputs used to produce goods for export. Set as a percentage of the export FOB value, varying by HS code and adjusted by the State Administration of Taxation. Rebates of 13%, 9%, 6%, or 0% are typical for chemical exports. The rebate is the single largest policy lever the Chinese government uses to influence which chemicals are exported and at what scale.
