EU Drafts Update to REACH Annex XVII to Further Regulate CMR Substances

On January 9, 2026, the European Commission released a draft proposal to technically update Annex XVII of the REACH Regulation. This aims to align with the new hazard classifications added under the CLP Regulation in 2024 and 2025. The core amendments involve expanding the list of restricted Carcinogenic, Mutagenic or Toxic for Reproduction (CMR) substances.
