Nitrogen (N2) under AICIS

N2 · 氮气

Status: Listed. Nitrogen 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 nitrogen. Australia has substantial domestic industrial-N2 production from cryogenic ASU operations (BOC Australia / Linde + Air Liquide Australia + Coregas, on-site supply at refineries + steel mills + petrochemical sites); structurally domestic-supplied. ChAFTA preferential zero-duty applies for any Chinese-origin imports (rare). **FSANZ Standard 1.2.4 (food additives) recognises N2 as E941** for food use (verify against https://www.foodstandards.gov.au/ before relying). **TGA listing or registration** required for medical-gas N2 (verify against https://www.tga.gov.au/).

AICIS treats nitrogen as a routine listed industrial chemical with low hazard profile (Press. Gas + simple-asphyxiant). **FSANZ Standard 1.2.4 E941 for food plus TGA for medical-gas**. NO active Australian AD/CVD case. ChAFTA preferential zero-duty. Australia domestic-supplied (BOC Australia / Linde + Air Liquide Australia + Coregas).

Listing and threshold

Status Listed
Tonnage threshold AICIS introducer registration required for >100 kg/year

Classifications under this regime

  • Listed Industrial Chemical on AICIS Inventory
  • Australian GHS classification: Press. Gas (compressed) or Press. Gas (refrigerated liquefied) + simple-asphyxiant
  • 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: UN 1066 Class 2.2 (compressed) or UN 1977 Class 2.2 (refrigerated liquefied)
  • Safe Work Australia: simple-asphyxiant; no specific WES typically established (verify against the current Safe Work Australia Workplace Exposure Standards at https://www.safeworkaustralia.gov.au/exposure-standards before relying)
  • **FSANZ Standard 1.2.4 E941** food additive (verify against https://www.foodstandards.gov.au/)
  • **TGA listing or registration** required for medical-gas N2 use
  • IARC: Not classified

Restrictions and conditions of use

  • NO active Australian AD/CVD case on Chinese nitrogen currently
  • WHS Regulation 2011 (Press. Gas + simple-asphyxiant)
  • ChAFTA preferential zero-duty applies (HS 280430)
  • FSANZ Standard 1.2.4 compliance for food-grade use
  • TGA registration for medical-gas N2

Importer obligations

AICIS registration required. **Australia is structurally domestic-supplied for industrial N2 (BOC Australia / Linde + Air Liquide Australia + Coregas captive ASU)**; Chinese-origin imports rare due to low value-density and shipping logistics.

Required documents

  • AICIS registration certificate (annual)
  • WHS-compliant SDS (Press. Gas + simple-asphyxiant)
  • Customs entry (ICS / ABF) with HS 280430
  • ChAFTA Form CO
  • ADG 7.7 documentation for UN 1066 / UN 1977 Class 2.2
  • FSANZ / TGA certifications for food and medical-gas 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 E941 for food use plus TGA for medical-gas use
  • Australia structurally domestic-supplied for industrial N2 (BOC Australia / Linde + Air Liquide Australia + Coregas captive ASU)
