Sulfuric acid under IECSC

H2SO4 · 硫酸

Status: Listed. Sulfuric acid is on the IECSC public portion as a foundational industrial chemical. New-substance notification under MEE Decree No. 7 (2010) is NOT required. Sulfuric acid is on China's Catalog of Hazardous Chemicals (2015 edition, entry 1721) and on the more restrictive Easily-Made Drugs Precursor Chemicals Catalog (《易制毒化学品管理条例》 Category 3); domestic distribution requires the corresponding precursor permit chain.

Sulfuric acid is comfortably IECSC-listed but the Easily-Made Drugs Precursor Catalog Category 3 listing adds the Public Security Bureau permit chain on top of the standard hazardous-chemicals permit chain: three permits per handover, not two. Battery-grade (>98% purity) is the lane-defining premium for electronics and EV battery exports; technical-grade is the bulk fertiliser-feed lane. China is the world's largest producer (~85 Mt/yr) so the export side is structural; the documentation gap is usually on the precursor permit, not the SDS.

Import Card

Before you order sulfuric acid from China, see its register listing, the duty, anti dumping cases and a supplier check on one card, each with its source and date.

Listing and threshold

Substance Sulfuric acid (CAS 7664-93-9), H2SO4
Regime China Inventory of Existing Chemical Substances (IECSC), administered by the Ministry of Ecology and Environment (MEE)
Jurisdiction People's Republic of China
Status Listed
Tonnage threshold No new-substance threshold applies. General hazardous-chemical handling permits and the precursor-chemicals registration apply above MIIT / MEE / Public Security Bureau thresholds.

Classifications under this regime

  • Listed in China's Catalog of Hazardous Chemicals (《危险化学品目录》, 2015 version, entry 1721)
  • Hazard category: Class 8 corrosive (UN 1830 / UN 2796 / UN 1832 in domestic GB labelling)
  • GB 30000.5-2013 GHS: Skin Corrosion Cat 1A, Carcinogen Cat 1A (mists)
  • NOT on the China State Council's Highly Toxic Chemicals Catalog (《剧毒化学品名录》)
  • Listed on the Easily-Made Drugs Precursor Chemicals Catalog (《易制毒化学品管理条例》) Category 3: methamphetamine precursor controls

Restrictions and conditions of use

  • Hazardous Chemicals Operation Permit (危险化学品经营许可证) required for distributors and end-users
  • Hazardous Chemicals Storage Approval required for storage above 1 t in single facility
  • Easily-Made Drugs Precursor Permit (易制毒化学品购销备案证明) required for purchase / sale of bulk sulfuric acid; Public Security Bureau handles registration
  • Concentrations >70% trigger additional Public Security Bureau monitoring on transactions
  • No specific export-restriction or quota system applies; 0% VAT export rebate per current bulletin (down from 9% in earlier years)

Importer obligations

For Chinese-origin sulfuric acid exported abroad, no IECSC obligation falls on the foreign importer. For inbound sulfuric-acid imports into China (rare; China is a net exporter, world's largest producer), the Chinese importer must verify IECSC listing (it is listed) and hold the Hazardous Chemicals Import Filing at the destination customs port. Sourzi-side practice: IECSC compliance is verified via GACC databases and built into the export documentation pack; the precursor-permit chain on the Chinese side is the documentation hot-spot.

Required documents

  • GACC export declaration with HS code 280700
  • GHS-compliant SDS in Simplified Chinese per GB/T 17519-2013 (effective 31 January 2014, references UN GHS 4th revised edition; verify against the current version of GB/T 17519 at https://www.codeofchina.com/standard/GBT17519-2013.html)
  • Manufacturer's Hazardous Chemicals Operation Permit copy
  • Easily-Made Drugs Precursor Permit copy from manufacturer (used by export-side broker for verification)
  • Test certificate (合格证) for grade verification (battery, technical, chamber acid)

Common compliance traps

The pitfalls that have bitten importers on this lane in the past. None of these is theoretical.

  • Easily-Made Drugs Precursor Catalog Category 3 listing means the Public Security Bureau is in the chain: manufacturer, distributor, and export-broker handovers all need permit verification
  • Battery-grade and electronic-grade sulfuric acid (>98% purity, low Fe / Cl / heavy-metal spec) commands separate quality-certification audits
  • GACC sometimes blocks shipments if SDS is missing the Chinese-only fields (mainland-China emergency contact, GHS Chinese pictograms)
  • 0% VAT export rebate (down from 9% historically) makes the China-export economics tighter; battery-grade premium reflects the absent rebate
