Ammonium hydroxide (ammonia solution) under AICIS

NH4OH (NH3 + H2O) · 氢氧化铵 / 氨水

Status: Listed. Ammonium hydroxide is on the AICIS Inventory of Industrial Chemicals as a Listed Industrial Chemical. **SUSMP / Poisons Standard Schedule 5 or 6 applies at concentrated industrial-grade ≥10% NH3** (verify the current Schedule entry against https://www.tga.gov.au/access-and-supply/poisons-standard before relying); household-grade (typically <5% NH3) is unscheduled. NOT on Australian Drug Control Act precursor list. NO active Australian AD/CVD case on Chinese-origin ammonium hydroxide. Australia has substantial domestic ammonia production (Incitec Pivot Phosphate Hill Queensland + Yara Pilbara Western Australia + Orica Kooragang Island NSW Haber-Bosch ammonia plants) with downstream NH4OH solution preparation; structurally domestic-supplied. ChAFTA preferential zero-duty applies for Chinese-origin imports.

AICIS treats ammonium hydroxide as a routine listed industrial chemical with **moderate hazard profile** (Skin Corr. 1B + Eye Dam. 1 + STOT SE 3 + Aquatic Acute 1; SUSMP Schedule 5 or 6 at industrial-grade). NO active Australian AD/CVD case. ChAFTA preferential zero-duty. Australia domestic-supplied (Incitec Pivot + Yara Pilbara + Orica Kooragang Island).

Restrictions and conditions of use

  • NO active Australian AD/CVD case on Chinese ammonium hydroxide currently
  • WHS Regulation 2011 (Skin Corr. 1B + Eye Dam. 1 + STOT SE 3 + Aquatic Acute 1)
  • ChAFTA preferential zero-duty applies (HS 282814)
  • SUSMP Schedule 5 or 6 at concentrated industrial-grade

Importer obligations

AICIS registration required. **Australia has substantial domestic ammonia production (Incitec Pivot Phosphate Hill QLD + Yara Pilbara WA + Orica Kooragang Island NSW Haber-Bosch ammonia plants) with downstream NH4OH solution preparation; structurally domestic-supplied.**

Required documents

  • AICIS registration certificate (annual)
  • WHS-compliant SDS (Skin Corr. 1B + Eye Dam. 1 + Aquatic Acute 1)
  • Customs entry (ICS / ABF) with HS 282814

  • ADG 7.7 documentation for UN 2672 Class 8 PG III or UN 2073 Class 2.2

Common compliance traps

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

  • AICIS registration must be CURRENT at customs clearance
  • SUSMP Schedule 5 or 6 at concentrated industrial-grade
  • NO active Australian AD/CVD case
  • ChAFTA preferential zero-duty applies
  • Australia structurally domestic-supplied (Incitec Pivot QLD + Yara Pilbara WA + Orica Kooragang Island NSW)
