Phosphorus pentoxide (P2O5) under IECSC

P2O5 (P4O10) · 五氧化二磷

Status: Listed. Phosphorus pentoxide is on the IECSC public portion. **On China's Catalog of Hazardous Chemicals at industrial-grade purity** (verify the specific entry against the most recent MEE Catalog of Hazardous Chemicals before relying); GB 6944 Class 8 PG II transport status applies. NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **China VAT export rebate** for P2O5 (HS 280910) per current inorganic chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing). Major Chinese P2O5 producers (typically integrated with phosphorus electric-arc operations): Yunnan Yuntianhua, Guizhou Kailin Phosphate, Hubei Xingfa Group, Hubei Yihua, Wengfu Group; verify each producer-site pair against the producer's public website before relying on a specific plant. **Hazardous Chemicals Operation Permit required** at producer plus distributor sites.

Phosphorus pentoxide is comfortably IECSC-listed but **on Catalog of Hazardous Chemicals at industrial-grade purity** (Hazardous Chemicals Operation Permit required at producer + distributor sites). NOT on Highly Toxic, NOT on Easily-Made Drugs. **China VAT export rebate** rate per current schedule (verify before invoicing). Major Chinese producers integrated with phosphorus electric-arc operations.

Listing and threshold

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

  • On Catalog of Hazardous Chemicals at industrial-grade purity (verify against the most recent MEE Catalog before relying)
  • GB 6944-2012 transport: Class 8 PG II (UN 1807 corrosive)
  • NOT on Highly Toxic Chemicals Catalog
  • NOT on Easily-Made Drugs Catalog
  • GB/T 17519-2013 Chinese SDS standard
  • GACC HS code: 280910
  • IARC: Not classified

Restrictions and conditions of use

  • **Hazardous Chemicals Operation Permit required** at producer plus distributor sites (verify against the most recent MEE Catalog before relying)
  • **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 (Skin Corr. 1A + Eye Dam. 1 + violent water-reaction)
  • GB 6944 Class 8 PG II transport classification applies

Importer obligations

For Chinese-origin P2O5 exported abroad, no IECSC obligation falls on the foreign importer. Major Chinese producers: Yunnan Yuntianhua, Guizhou Kailin, Hubei Xingfa, Hubei Yihua, Wengfu Group.

Required documents

  • GACC export declaration HS 280910
  • GHS Chinese SDS per GB/T 17519
  • Hazardous Chemicals Operation Permit at producer + distributor sites
  • GB 6944-2012 Class 8 PG II transport documentation

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 industrial-grade purity
  • **Hazardous Chemicals Operation Permit required** at producer + distributor sites
  • **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
  • Major Chinese producers (P electric-arc captive): Yunnan Yuntianhua, Guizhou Kailin, Hubei Xingfa, Hubei Yihua, Wengfu Group (verify each producer-site pair)
  • **Drying / dehydrating agent + chemical synthesis + glass / ceramic flux + fire-retardant downstream chains** dominate Chinese consumption
