Phosphoric acid under IECSC

H3PO4 · 磷酸

Status: Listed. Phosphoric acid is on the IECSC public portion. **Phosphoric acid IS on China's Catalog of Hazardous Chemicals** (Skin Corr. 1B classification). Hazardous Chemicals Operation Permit required. NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **China VAT export rebate** for phosphoric acid (HS 280920) per current inorganic chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing; phosphate-chain rebates have been adjusted multiple times to manage domestic fertiliser supply). China dominates global wet-process phosphoric acid capacity (verify percent-of-global share against IFA or ICIS before quoting; prior reports cited China at well above 40 percent of global ~50 Mt/yr P2O5 capacity) led by Yunnan Yuntianhua, Hubei Xingfa Chemicals Yichang, Hubei Yihua Group, Wengfu Group Guizhou, Guizhou Phosphate Chemical.

Phosphoric acid is comfortably IECSC-listed but IS on Catalog of Hazardous Chemicals. NOT on Highly Toxic, NOT on Easily-Made Drugs. **China VAT export rebate** rate per current inorganic chemicals chapter schedule (verify before invoicing). **China has periodically applied phosphate export controls** (verify against the most recent GACC / MOFCOM notice before relying). China dominates global wet-process phosphoric acid capacity. Production: wet-process via sulfuric acid plus phosphate rock (~95 percent of global capacity).

Restrictions and conditions of use

  • **Hazardous Chemicals Operation Permit IS required**
  • **China VAT export rebate** rate per current inorganic chemicals chapter schedule (verify against the most recent MOF / GACC rebate notice before invoicing; phosphate-chain rebates have been adjusted multiple times to manage domestic fertiliser supply)
  • **China has periodically applied phosphate export controls** (export licence requirement, additional export tax, or rebate cancellation) to manage domestic fertiliser availability (verify against the most recent GACC / MOFCOM notice before relying on a specific export-tax or rebate position)
  • GB/T 17519 Chinese SDS required

Importer obligations

For Chinese-origin phosphoric acid exported abroad, no IECSC obligation falls on the foreign importer. Major Chinese producers: Yunnan Yuntianhua, Hubei Xingfa Chemicals Yichang, Hubei Yihua Group, Wengfu Group Guizhou, Guizhou Phosphate Chemical.

Required documents

  • GACC export declaration HS 280920
  • GHS Chinese SDS per GB/T 17519
  • Hazardous Chemicals Operation Permit chain
  • GB 6944-2012 Class 8 transport doc
  • **Phosphate export licence where applicable** (verify against the most recent GACC / MOFCOM notice before relying)
