TDI mixed isomers (toluene diisocyanate, 80:20 + 65:35 blends) under AICIS

C9H6N2O2 · 甲苯二异氰酸酯

Status: Listed. TDI is on the AICIS Inventory of Industrial Chemicals as a Listed Industrial Chemical. Australia adopted the GHS classification matching REACH (Carc 2 + Acute Tox. 2 inhalation + Resp. Sens. 1 + Skin Sens. 1 + STOT SE 3 + STOT RE 2). **SUSMP Schedule 7 (Dangerous Poison) applies for industrial-grade TDI above concentration cutoffs** (heavier than MDI batch 30 SUSMP Schedule 6; same as aniline batch 26 + EO batch 28 + PO batch 29). NOT on Australian Drug Control Act precursor list. NO active Australian AD/CVD case. Australia has limited domestic TDI production capacity; imports primarily flow to flexible PU foam (mattress + furniture + automotive seat) industries. ChAFTA preferential zero-duty applies for Chinese-origin imports.

AICIS treats TDI as a routine listed industrial chemical with **SUSMP Schedule 7 (Dangerous Poison) scheduling for industrial-grade above concentration cutoffs** (heavier than MDI batch 30 Schedule 6 due to TDI Acute Tox. 2 inhalation). The operational compliance work is substantial (annual AICIS registration, WHS-compliant SDS, ADG 7.7 Class 6.1 transport, ventilated storage for bulk, Schedule 7 labelling, occupational asthma surveillance for Resp. Sens. 1). NO active Australian AD/CVD case. ChAFTA preferential zero-duty makes Chinese-origin TDI competitive. Australia has **limited domestic TDI production**; imports primarily flow to flexible PU foam (mattress + furniture + automotive seat) industries.

Listing and threshold

Substance TDI mixed isomers (toluene diisocyanate, 80:20 + 65:35 blends) (CAS 26471-62-5), C9H6N2O2
Regime Australian Industrial Chemicals Introduction Scheme (AICIS), administered by the Department of Health
Jurisdiction Australia
Status Listed
Tonnage threshold AICIS introducer registration required for any business introducing >100 kg/year of any industrial chemical

Classifications under this regime

  • Listed Industrial Chemical on AICIS Inventory
  • Australian GHS classification: Carc. 2 (H351), Acute Tox. 2 inhalation (H330), Skin Irrit. 2 (H315), Eye Irrit. 2 (H319), Resp. Sens. 1 (H334), Skin Sens. 1 (H317), STOT SE 3 (H335), STOT RE 2 (H373), Aquatic Chronic 3 (H412)
  • Signal word: DANGER. GHS pictograms: GHS06 + GHS08
  • **SUSMP Schedule 7 (Dangerous Poison)** applies for industrial-grade TDI above concentration cutoffs (heavier than MDI batch 30 Schedule 6)
  • NOT on Australian Drug Control Act precursor list
  • Australian Dangerous Goods Code (ADG 7.7): Class 6.1 (toxic substance), UN 2078, Packing Group II
  • Safe Work Australia workplace exposure standard: 0.02 ppm 8-hr TWA
  • **IARC: Group 2B (possibly carcinogenic to humans)**

Restrictions and conditions of use

  • No AICIS-specific use restrictions for industrial-grade TDI above concentration cutoffs
  • SUSMP Schedule 7 retail packaging rules apply for industrial-grade above cutoffs
  • NO active Australian AD/CVD case on Chinese-origin TDI currently
  • WHS Regulation 2011 hazardous-chemicals handling requirements apply
  • NFPA-equivalent toxic substance storage requirements apply for bulk; ventilated storage
  • ChAFTA preferential zero-duty applies to Chinese-origin TDI (HS 292910)
  • **Workplace exposure-control + occupational asthma surveillance + medical surveillance** required for Resp. Sens. 1 substances + Acute Tox. 2 inhalation

Importer obligations

The Australian importer of record must be registered with AICIS. **SUSMP Schedule 7 (Dangerous Poison) compliance + workplace exposure-control + occupational asthma surveillance + medical surveillance is the dominant practitioner overhead** (heavier than MDI batch 30 SUSMP Schedule 6 due to TDI Acute Tox. 2 inhalation). Workplace handling SDS drives WHS hazardous-chemicals register entry; ventilated storage for bulk receipt. Australia has limited domestic TDI production; imports primarily flow to flexible PU foam (mattress + furniture + automotive seat) industries. Major Australian downstream consumers: Sealy Australia + Sleepmaker Australia (mattress flexible PU foam), Dunlop Foams Australia (general flexible foam), Australian automotive sector (seat foam).

Required documents

  • AICIS introducer registration certificate (annual)
  • WHS-compliant Safety Data Sheet (Safe Work Australia model code format) reflecting H315 / H317 / H319 / H330 / H334 / H335 / H351 / H373 / H412 classification
  • Customs entry (ICS / ABF) with HS code 292910
  • **SUSMP Schedule 7 (Dangerous Poison) labelling compliance** for industrial-grade above cutoffs
  • ChAFTA Form CO certificate of origin for preferential treatment
  • Industrial-grade specification certificate
  • ADG 7.7 Class 6.1 dangerous-goods transport documentation

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
  • WHS hazardous-chemicals register entry required at handling facilities; ventilated storage for bulk
  • **SUSMP Schedule 7 (Dangerous Poison) compliance is the dominant practitioner overhead** for industrial-grade above cutoffs (heavier than MDI batch 30 SUSMP Schedule 6 due to TDI Acute Tox. 2 inhalation)
  • Carc 2 + Acute Tox. 2 inhalation + Resp. Sens. 1 hazard profile drives heavier WHS workplace exposure-control overhead than MDI batch 30
  • NOT on Australian Drug Control Act precursor list
  • NO active Australian AD/CVD case on Chinese TDI currently
  • ChAFTA preferential zero-duty makes Chinese-origin TDI competitive vs Korean (Hyosung Chemicals + Kumho Mitsui), Japanese (Mitsui Chemicals + Sumitomo Chemical) alternatives
  • Australian end-use is dominated by flexible PU foam (mattress + furniture + automotive seat) industries
