Industrial Bases from China
Sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, ammonia solutions, and other industrial bases.
Industrial bases are the alkaline workhorses of industrial chemistry, caustic soda (sodium hydroxide) for pulp and paper, soap and detergent, alumina production, and chemical synthesis; potassium hydroxide for biodiesel, soft soap, and battery electrolytes; soda ash (sodium carbonate) for glass, detergent, and chemical manufacturing; sodium bicarbonate for food, pharmaceuticals, and animal feed; ammonia solutions for refrigeration, fertilizer chemistry, and water treatment.
Most industrial bases are Class 8 DG corrosive cargo. Caustic soda in flake or pearl form (50% NaOH equivalent in solid) and in 32 to 50 percent aqueous solution are both Class 8 PG II, strict UN packaging requirements (Y-coded drums or IBCs), full DG documentation chain, careful loading supervision. Soda ash and sodium bicarbonate are non-DG and ship in 25 kg paper bags or 1 MT jumbo bags.
China is the dominant global producer of caustic soda and soda ash, with the major factory clusters in Shandong, Jiangsu, Tianjin, and Hebei. Producer selection drives quality consistency, caustic soda spec parameters (NaOH content, sodium chloride impurity, iron content, sodium chlorate residue) vary materially between producers, and certain end uses (rayon production, alumina precipitation, food-grade applications) need producer-specific qualification.

Documentation chain
Terms that come up on every industrial bases shipment
-
IMDG Code, International Maritime Dangerous Goods Code
The international rulebook for shipping dangerous goods by sea. Defines classification, packaging, labelling, documentation, and segregation requirements for hazardous cargo on container vessels.
-
PG I / II / III, Packing Group
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.
-
MSDS / SDS, Material Safety Data Sheet
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.
-
FOB, Free On Board
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.
-
SGS, SGS Pre-Shipment Inspection
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.
