EU CLP Regulation 22nd revision takes effect on May 1

The 22nd revision of the EU CLP Regulation (EU 2024/2564) officially took effect on May 1, 2026. The revision adds 27 substances with harmonized classification, updates the hazard classification of 16 existing substances, and deletes 7 entries that are no longer applicable. The new regulation requires all chemicals and mixtures sold in the EU market to be relabeled with updated hazard labels and to have safety data sheets (SDS) updated to ensure accurate identification of hazardous properties throughout the supply chain. The changes directly affect Chinese chemical exporters to the EU across base chemicals, fine chemicals, pesticides, coatings, and other categories.
