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.

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
