Magnesium oxide (magnesia) under AICIS

MgO · 氧化镁

Status: Listed. Magnesium oxide is on the AICIS Inventory of Industrial Chemicals as a Listed Industrial Chemical. **NOT typically scheduled under SUSMP / Poisons Standard** at retail-grade (verify against the current SUSMP / Poisons Standard before relying). NOT on Australian Drug Control Act precursor list. NO active Australian AD/CVD case on Chinese-origin magnesium oxide. Australia has domestic magnesite mining (e.g. Queensland Magnesia Pty Ltd Kunwarara Queensland operations; verify against producer's public website before relying); imports occur from China for refractory + industrial grades. ChAFTA preferential zero-duty applies for Chinese-origin imports. **FSANZ Standard 1.2.4 (food additives) recognises magnesium oxide as E530** for food use (verify against https://www.foodstandards.gov.au/ before relying). **TGA listing or registration** required for products placed as therapeutic antacid / laxative / magnesium supplement (verify against https://www.tga.gov.au/).

AICIS treats magnesium oxide as a routine listed industrial chemical with low hazard profile beyond respirable dust handling. **FSANZ Standard 1.2.4 E530 for food plus TGA for therapeutic antacid / laxative / Mg supplement**. NO active Australian AD/CVD case. ChAFTA preferential zero-duty. Australia has domestic magnesite mining at Queensland Magnesia Kunwarara Queensland with parallel Chinese imports.

Import Card

Before you order magnesium oxide (magnesia) from China, see its register listing, the duty, anti dumping cases and a supplier check on one card, each with its source and date.

Classifications under this regime

  • Listed Industrial Chemical on AICIS Inventory
  • Australian GHS classification: NOT typically classified as hazardous beyond particulate dust
  • NOT typically scheduled under SUSMP / Poisons Standard at retail-grade (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 regulated
  • Safe Work Australia: WES for inspirable / respirable particulate dust applies (verify against the current Safe Work Australia Workplace Exposure Standards at https://www.safeworkaustralia.gov.au/exposure-standards before relying on specific limit)
  • **FSANZ Standard 1.2.4 E530** food additive (verify against https://www.foodstandards.gov.au/)
  • **TGA listing or registration** required for therapeutic antacid / laxative / magnesium supplement use
  • IARC: Not classified

Restrictions and conditions of use

  • NO active Australian AD/CVD case on Chinese magnesium oxide currently
  • WHS Regulation 2011 (low-hazard handling, respirable dust applies)
  • ChAFTA preferential zero-duty applies (HS 251990)
  • FSANZ Standard 1.2.4 compliance for food-grade use
  • TGA registration for therapeutic antacid / laxative / magnesium supplement use

Importer obligations

AICIS registration required. Australia has domestic magnesite mining (Queensland Magnesia Kunwarara Queensland operations); imports occur from China for refractory and industrial grades.

Required documents

  • AICIS registration certificate (annual)
  • WHS-compliant SDS (with respirable particulate dust / fume handling notes)
  • Customs entry (ICS / ABF) with HS 251990
  • ChAFTA Form CO
  • FSANZ / TGA certifications for food and therapeutic grades

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
  • NOT typically scheduled under SUSMP / Poisons Standard
  • NO active Australian AD/CVD case
  • ChAFTA preferential zero-duty applies
  • FSANZ Standard 1.2.4 E530 for food use plus TGA for therapeutic antacid / laxative / Mg supplement
  • Australia has domestic magnesite mining (Queensland Magnesia Kunwarara Queensland operations); imports occur from China
  • Safe Work Australia respirable particulate dust WES applies (verify limit before relying)
