Sodium hypochlorite under IECSC

NaClO · 次氯酸钠

Status: Listed. Sodium hypochlorite is on the IECSC public portion. **Sodium hypochlorite 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 sodium hypochlorite (HS 282890) per current inorganic chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing). China dominates global sodium hypochlorite chlor-alkali capacity (verify against ICIS or S&P Commodity Insights before quoting) led by Sinopec multi-site, Wanhua Chemical Yantai, Hengli Petrochemical Dalian, China National Salt Industry Corporation (CNSIC), Befar Group Shandong.

Sodium hypochlorite 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). **Disinfectant Hygiene Permit** where placed as disinfectant product. China dominates global chlor-alkali capacity. Production: chlor-alkali co-product (Cl2 absorption in NaOH).
