• A delegated regulation published by the European Commission revising the CLP Regulation establishes new hazard classes and criteria for the classification, labelling, and packaging of chemicals and mixtures.
• It applies to every chemical compound and mixture put on the EU market in accordance with REACH. Additionally, it applies to the active ingredients found in plant protection and biocidal preparations, which are typically given priority in the EU for a unified categorization.
• Manufacturers, importers, downstream consumers, and distributors who sell chemicals on the EU market are subject to this legislation. Member States will also refer to the new hazard classes and standards when submitting proposals for standardized labelling and classification.
• The new hazard classes are:

1. ED HH in Category 1 and Category 2 (endocrine disruption for human health)
2. ED ENV in Category 1 and Category 2 (endocrine disruption for the environment)
3. PBT (persistent, bioaccumulative, toxic), vPvB (very persistent, very bioaccumulative)
4. PMT (persistent, mobile, toxic); vPvM (very persistent, very mobile).

• As of April 20, 2023, the new regulations are in effect. Manufacturers, importers, downstream users, and distributors can now self-classify their chemicals and mixtures in accordance with the proposed Harmonized Classification and Labelling (CLH) with the new danger classes made by the Member States.
• From the time the Delegated Regulation enters effect, there are transitional periods during which producers, importers, downstream users, and distributors are not yet compelled to categorize their substances or mixtures in accordance with the new danger classes. These times allow for the voluntary application of the new danger classes.
