AICIS opens public consultation on 2026 revisions to the Industrial Chemicals Categorisation Guidelines (incl. Sept 2026 high-hazard list update preview)

AICIS opened consultation on proposed revisions to the Industrial Chemicals Categorisation Guidelines for 2026, including two specific proposals: (1) add 5 more chemicals to Part 6.5.2 (salts/esters with potential developmental toxicity) and invite suggestions for other chemicals; and (2) replace the current dual definition of “chemical identity holder” with a single new definition. The notice also previews the September 2026 annual update to the “list of chemicals with high hazards for categorisation,” indicating it will add 294 chemicals, update 121 entries, remove 2 chemicals, and correct one CAS number. Compliance teams should monitor and, where relevant, submit comments and begin impact screening for categorisation changes and potential re-categorisation impacts in Sept 2026 once finalised.
