Sulfur (elemental) under IECSC

S8 · 硫磺

Status: Listed. Sulfur is on the IECSC public portion. **On China's Catalog of Hazardous Chemicals at fine-powder grade as Flam. Sol. 2** (verify the specific entry against the most recent MEE Catalog of Hazardous Chemicals before relying; solid block / lump typically not on Catalog). NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **China VAT export rebate** for sulfur (HS 250300) per current inorganic chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing). **China is structurally net-IMPORTER of sulfur for sulfuric-acid + phosphate-fertiliser captive consumption (~30% of global sulfur trade flows into China; verify against ICIS or S&P before quoting); China sources merchant sulfur from Saudi Aramco + Russian gas + Canadian Alberta tar-sands + Qatar QatarEnergy + Iran NIOC + UAE ADNOC + Kazakhstan Tengizchevroil**. Major Chinese sulfur captive sources at Sinopec + CNPC + CNOOC refinery / sour-gas plants (Claus-process recovery); verify each producer-site pair against the producer's public website before relying on a specific plant.

Sulfur is comfortably IECSC-listed but **on Catalog of Hazardous Chemicals at fine-powder grade as Flam. Sol. 2** (Hazardous Chemicals Operation Permit required at fine-powder grade; solid block / lump typically unregulated). NOT on Highly Toxic, NOT on Easily-Made Drugs. **China VAT export rebate** rate per current schedule (verify before invoicing). **China is structurally net-IMPORTER of sulfur** for H2SO4 + phosphate-fertiliser captive consumption; merchant Chinese-origin sulfur exports are rare. Major sources: Saudi Aramco + Russian gas + Canadian Alberta tar-sands + Qatar + Iran + UAE + Kazakhstan.

Listing and threshold

Substance Sulfur (elemental) (CAS 7704-34-9), S8
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. Hazardous Chemicals Operation Permit required at fine-powder grade (verify against the most recent MEE Catalog before relying)

Classifications under this regime

  • On Catalog of Hazardous Chemicals at fine-powder grade as Flam. Sol. 2 (verify against the most recent MEE Catalog before relying; solid block / lump typically not on Catalog)
  • GB 6944-2012 transport: Class 4.1 PG III at fine-powder grade (UN 1350); solid block / lump typically unregulated
  • NOT on Highly Toxic Chemicals Catalog
  • NOT on Easily-Made Drugs Catalog
  • GB/T 17519-2013 Chinese SDS standard
  • GACC HS code: 250300
  • **Pharma-grade compliance with Chinese Pharmacopoeia (ChP)** where placed as pharma-grade sulfur (verify monograph reference against the most recent ChP edition before relying)

Restrictions and conditions of use

  • **Hazardous Chemicals Operation Permit required** at fine-powder grade (verify against the most recent MEE Catalog before relying; solid block / lump typically not requiring Permit)
  • **China VAT export rebate** rate per current inorganic chemicals chapter schedule (verify against the most recent MOF / GACC rebate notice before invoicing)
  • GB/T 17519 Chinese SDS required

Importer obligations

For Chinese-origin sulfur exported abroad, no IECSC obligation falls on the foreign importer; however, **note that China is structurally net-IMPORTER of sulfur** so merchant Chinese exports are rare. Major Chinese captive sources: Sinopec + CNPC + CNOOC refinery / sour-gas plants Claus-process recovery.

Required documents

  • GACC export declaration HS 250300
  • GHS Chinese SDS per GB/T 17519
  • Hazardous Chemicals Operation Permit at fine-powder grade
  • GB 6944-2012 Class 4.1 PG III transport documentation at fine-powder grade
  • Pharma-grade ChP certification where applicable

Common compliance traps

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

  • On Catalog of Hazardous Chemicals at fine-powder grade as Flam. Sol. 2
  • **Hazardous Chemicals Operation Permit required** at fine-powder grade
  • **China VAT export rebate** rate (verify against the most recent MOF / GACC rebate notice before invoicing)
  • NOT on Highly Toxic, NOT on Easily-Made Drugs
  • **China is structurally net-IMPORTER of sulfur (~30% of global trade flows into China for H2SO4 + phosphate-fertiliser captive consumption; sources include Saudi Aramco + Russian gas + Canadian Alberta tar-sands + Qatar + Iran + UAE + Kazakhstan)**
  • Major Chinese captive sources (Claus-process refinery recovery): Sinopec + CNPC + CNOOC
  • **Sulfuric-acid feedstock + phosphate-fertiliser + rubber vulcanisation + fungicide downstream chains** dominate Chinese consumption
