EU CLP transition: formulation changes can end your grace period

Regulation (EU) 2024/2865 changed the CLP framework and, together with Delegated Regulation (EU) 2023/707, brought in new hazard classes (ED, PBT/vPvB, PMT/vPvM). Regulation (EU) 2025/2439 ("stop the clock") then postponed the label-format and advertising provisions to 1 January 2028. The classification duties for the new hazard classes were not postponed: substances already on the market are due on 1 November 2026, mixtures already on the market on 1 May 2028. The transition rules are not only about dates — placing a reformulated mixture on the market can end the grace period the original mixture relied on.
