Guidance on new CLP criteria released

The long-awaited update of the CLP Guidance is available on the ECHA website since November 2024. Instead of finding all the information in one document as before, the integration of the new hazard classes (endocrine disruptors with an effect on human or environmental health; persistent substances - PBT/vPvB and PMT/vPvM) has made it necessary to split it into five individual documents. This means that ECHA has provided the necessary guidelines for classification shortly before the May 1, 2025 deadline for substances newly placed on the market from then on. We are still waiting for important revisions of the sections on already existing hazard classes, such as the inclusion of the OECD Guideline No. 497 “Defined Approaches on Skin Sensitization”.
