NH4OH (NH3 + H2O) · 氢氧化铵 / 氨水

Status: Listed. Ammonium hydroxide is on the IECSC public portion. **On China's Catalog of Hazardous Chemicals at industrial-grade purity (≥10% NH3)** (verify the specific entry against the most recent MEE Catalog of Hazardous Chemicals before relying); GB 6944 Class 8 PG III (10-35% NH3) or Class 2.2 (>35% NH3) transport status applies. NOT on Highly Toxic Chemicals Catalog. NOT on Easily-Made Drugs Catalog. **China VAT export rebate** for ammonium hydroxide (HS 282814) per current inorganic chemicals chapter rebate schedule (verify the rate against the most recent MOF / GACC rebate notice before invoicing). **Hazardous Chemicals Operation Permit required** at producer plus distributor sites. Major Chinese producers: Sinopec + CNPC ammonia plants, Yara China, Jiangsu Linggu Chemical, Henan Xinlianxin Fertilizer, Hubei Yihua; verify each producer-site pair against the producer's public website before relying.

Ammonium hydroxide is **on Catalog of Hazardous Chemicals at industrial-grade purity ≥10% NH3** (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).
