New CLP hazard classes: the next important deadline is approaching

Commission Delegated Regulation (EU) 2023/707 introduced four new CLP hazard classes — endocrine disruption (human health and environment), PBT/vPvB and PMT/vPvM. They already apply to new substances and mixtures placed on the market. The next deadline is 1 November 2026, when substances already on the EU market before 1 May 2025 must meet the new criteria; mixtures already on the market follow on 1 May 2028.

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.
