Vinyl chloride monomer (VCM, chloroethene) under IECSC

C2H3Cl · 氯乙烯

Status: Listed. VCM is on the IECSC public portion. **VCM IS on China's Catalog of Hazardous Chemicals** (Carc 1A + Muta 1B + Flam. Gas 1A + Press. Gas classification matching EU REACH harmonised). Hazardous Chemicals Operation Permit IS required. **VCM IS on China's Highly Toxic Chemicals Catalog**: Public Security Bureau supervision required. NOT on Easily-Made Drugs Catalog. **0% China VAT export rebate** for VCM (HS 290321). **VCM is structurally NOT internationally traded as bulk**; intra-complex captive consumption dominates for downstream PVC batch 10 production. China dominates global VCM capacity (verify percent-of-global share against ICIS or S&P Commodity Insights before quoting; prior reports cited approximately 50 percent at ~25 to 30 Mt/yr with substantial calcium-carbide-route legacy capacity).

VCM is comfortably IECSC-listed but IS on **BOTH the Catalog of Hazardous Chemicals AND the Highly Toxic Chemicals Catalog**. **0% China VAT export rebate**. **VCM is structurally NOT internationally traded as bulk**. China dominates global VCM capacity with substantial calcium-carbide-mercury-catalyst legacy capacity in Inner Mongolia + Xinjiang + Qinghai + Sichuan + Shanxi inland coal cluster. **MEE 2024-2025 policy mandates conversion to non-mercury catalyst by 2032 per Minamata Convention compliance**.

Listing and threshold

Substance Vinyl chloride monomer (VCM, chloroethene) (CAS 75-01-4), C2H3Cl
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

Classifications under this regime

  • Listed in China's Catalog of Hazardous Chemicals
  • **Listed in China's Highly Toxic Chemicals Catalog** (Public Security Bureau supervision)
  • NOT on Easily-Made Drugs Catalog
  • GB/T 17519-2013 Chinese SDS standard
  • GACC HS code: 290321
  • GB 6944-2012 Class 2.1, UN 1086, refrigerated liquefied or compressed

Restrictions and conditions of use

  • **Hazardous Chemicals Operation Permit IS required**
  • **Highly Toxic Chemicals Public Security Bureau permit chain** required
  • **0% China VAT export rebate**
  • GB/T 17519 Chinese SDS required
  • **MEE 2024-2025 policy guidance** restricts new calcium-carbide-mercury-catalyst capacity and mandates conversion to non-mercury catalyst by 2032 (Minamata Convention compliance; verify current MEE policy notice before relying)

Importer obligations

For Chinese-origin VCM exported abroad, no IECSC obligation falls on the foreign importer. **Highly Toxic Chemicals + Hazardous Chemicals dual-permit chain**. **VCM is structurally NOT internationally traded as bulk**; captive PVC chain consumption dominates. Major Chinese producers: chlor-alkali batch 45 ethylene-route multi-site (Sinopec Qilu Shandong, LG Chem Daya Bay Guangdong, Sumitomo Chemical Tianjin) plus calcium-carbide-acetylene legacy inland route (~50 percent of Chinese capacity, concentrated in Inner Mongolia, Xinjiang, Qinghai, Sichuan, Shanxi).

Required documents

  • GACC export declaration HS 290321
  • GHS Chinese SDS per GB/T 17519
  • Hazardous Chemicals Operation Permit chain
  • **Highly Toxic Chemicals Public Security Bureau permit chain documentation**
  • GB 6944-2012 transport doc

Common compliance traps

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

  • **Highly Toxic Chemicals + Hazardous Chemicals dual-permit chain is the heaviest IECSC compliance overhead**
  • **0% China VAT export rebate**
  • **VCM is structurally NOT internationally traded as bulk**; captive PVC chain consumption dominates
  • Major Chinese producers: chlor-alkali batch 45 ethylene-route multi-site (~50 percent), calcium-carbide-acetylene legacy route (~50 percent in Inner Mongolia + Xinjiang + Qinghai + Sichuan + Shanxi)
  • **Calcium-carbide-mercury-catalyst legacy route** raises Minamata Convention compliance concern; MEE 2024-2025 policy mandates conversion to non-mercury catalyst by 2032
  • Production: EDC batch 76 thermal cracking (~95 percent globally; ethylene route in chlor-alkali integrated complexes), calcium-carbide-acetylene-mercury-catalyst (~5 percent globally; predominantly Chinese inland coal cluster)
