Three new hazard classes for classifying, labelling and packaging (CLP) substances and mixtures entered into force on 20 April 2023. ECHA has published information on the application dates and related guidance.

The European Commission updated the Classification, Labelling and Packaging Regulation with the following hazard classes:

• endocrine disruptors (ED) for human health or the environment;
• persistent, bioaccumulative and toxic (PBT); very persistent and very bioaccumulative (vPvB); and
• persistent, mobile and toxic (PMT); very persistent and very mobile (vPvM)

Companies and Member State authorities can use current guidance on identifying endocrine disruptors and on PBT (persistence, bioaccumulation, toxicity) assessment until the guidance on applying the CLP criteria has been updated. It is expected to be ready in 2024.
