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.

ECHA updated the XML-based PCN format to Version 8 (27 April 2026, released with IUCLID 6 version 10), the format used to structure Poison Centre Notifications for hazardous mixtures under CLP Article 45 and Annex VIII. This is a format and validation update, not a new legal obligation by itself — but a 2026 ECHA enforcement pilot found 19% of inspected mixtures had no PCN submitted and 15% of labels were missing the UFI, so companies should treat format and UFI/composition consistency as an active compliance risk, not routine housekeeping.

The EU-wide proposal to restrict per- and polyfluoroalkyl substances (PFAS) under REACH Annex XVII — prepared by Denmark, Germany, the Netherlands, Norway and Sweden, and one of the broadest restriction proposals ever assessed under REACH — is still moving through ECHA's committees. RAC adopted its opinion on 3 March 2026; SEAC's sector-by-sector socio-economic assessment (14 sector modules) is ongoing, with a final opinion expected by the end of 2026. This is not yet an adopted restriction, but companies should not wait for final adoption before mapping PFAS uses and alternatives.

The European Commission then drafts a specific restriction proposal from the RAC/SEAC opinions for the REACH Committee to vote on.
ECHA is advancing a restriction proposal for certain chromium(VI) oxides, oxyacids and salts under REACH Annex XVII, covering electroplating, surface treatment, primers/slurry coatings and related use categories. The SEAC draft-opinion consultation closed on 17 August 2026; SEAC's final opinion is expected before the file goes to the European Commission. This is not yet a binding restriction, but affected companies should start mapping exposure, emissions and substitution options now.

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.
