Calcium oxide (quicklime) under AICIS

CaO · 氧化钙

Status: Listed. Calcium oxide is on the AICIS Inventory of Industrial Chemicals as a Listed Industrial Chemical. **SUSMP scheduling** for retail mixtures (verify against the current SUSMP / Poisons Standard before relying; not typically scheduled at industrial-grade bulk). NOT on Australian Drug Control Act precursor list. NO active Australian AD/CVD case on Chinese-origin calcium oxide. Australia has substantial domestic lime capacity (Adbri Limited Munster Western Australia plus regional operations, plus Cockburn Cement Western Australia; verify current operational status against the producers' public reporting before relying); structurally balanced. ChAFTA preferential zero-duty applies for Chinese-origin imports.

AICIS treats calcium oxide as a routine listed industrial chemical with **slaking-reaction moisture-control warning critical**. SUSMP scheduling for retail mixtures (verify before relying). NO active Australian AD/CVD case. ChAFTA preferential zero-duty. Australia has substantial domestic lime capacity (Adbri Limited Munster Western Australia plus regional operations, plus Cockburn Cement Western Australia; verify current status before relying).

Classifications under this regime

  • Listed Industrial Chemical on AICIS Inventory
  • Australian GHS classification: Skin Irrit. 2 (H315), Eye Dam. 1 (H318), STOT SE 3 (H335)
  • Signal word: DANGER. GHS pictograms: GHS05 + GHS07
  • SUSMP scheduling for retail mixtures (verify against the current SUSMP / Poisons Standard at https://www.tga.gov.au/products/scheduling-poisons-standard before relying)
  • NOT on Australian Drug Control Act precursor list
  • ADG 7.7: NOT typically regulated for industrial-grade CaO; UN 1910 listed but exemption applies (verify against the most recent ADG before relying)

Restrictions and conditions of use

  • SUSMP scheduling for retail mixtures (verify against the current SUSMP / Poisons Standard at https://www.tga.gov.au/products/scheduling-poisons-standard before relying)
  • NO active Australian AD/CVD case on Chinese calcium oxide currently
  • WHS Regulation 2011 hazardous-chemicals handling plus moisture-control warnings
  • ChAFTA preferential zero-duty applies (HS 252210)
  • AS/NZS 4020 certification typically required for water-treatment grade

Importer obligations

AICIS registration required. Australia has substantial domestic lime capacity (Adbri Limited Munster Western Australia plus regional operations, plus Cockburn Cement Western Australia; verify current status before relying); structurally balanced.

Required documents

  • AICIS registration certificate (annual)
  • WHS-compliant SDS reflecting H315 / H318 / H335 plus moisture-control warnings
  • Customs entry (ICS / ABF) with HS 252210
  • ChAFTA Form CO
  • AS/NZS 4020 certification for water-treatment grade where applicable

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 scheduling for retail mixtures (verify against the current SUSMP / Poisons Standard at https://www.tga.gov.au/products/scheduling-poisons-standard before relying)
  • NO active Australian AD/CVD case
  • ChAFTA preferential zero-duty applies
  • **Slaking-reaction moisture-control warning critical**
  • Australia has substantial domestic lime capacity (Adbri Limited Munster Western Australia plus regional operations, plus Cockburn Cement Western Australia; verify current status before relying)
