AICIS preview: upcoming 2026 Categorisation Guidelines changes (high-hazard list updates and other guideline revisions)

AICIS published a preview of upcoming changes to the 2026 Industrial Chemicals Categorisation Guidelines, including updates to the list of chemicals with high hazards for categorisation (new entries and updates to existing entries) and other guideline changes (as described on the preview page). Compliance impact: introducers should monitor and prepare for guideline revisions affecting categorisation decisions and potential eligibility for exempted/reported pathways, and review whether any introduced chemicals will fall into newly added or updated high-hazard entries once the updated guidelines apply.
