AICIS announces finalised revisions to Industrial Chemicals Categorisation Guidelines effective September 2026

AICIS published finalised changes to the Industrial Chemicals Categorisation Guidelines that will take effect from September 2026. The changes include: (1) updates to the ‘chemicals with high hazards for categorisation’ list (additions and updates, plus removals and a CAS correction); (2) amendments to Part 6.5.2 (developmental toxicity evidence) to add specified benzotriazole substances and clarify the ‘salt’ check (correcting earlier consultation wording); and (3) a clarified single definition of ‘chemical identity holder’ that affects how certain reporting-related provisions apply. Compliance teams should assess impacts on categorisation of introductions (especially for chemicals not listed on the AIIC), internal hazard list screening, and any reporting/recordkeeping processes that depend on the ‘chemical identity holder’ definition.
