On 10 December 2024, revised EU rules on the classification, labelling, and packaging (CLP) of chemicals officially entered into force. These updates mark a significant step in the European Commission’s ongoing efforts to strengthen chemical safety, increase transparency, and better protect both human health and the environment. The new regulation introduces clearer requirements for hazard communication and lays out specific obligations for manufacturers, importers, and downstream users of chemicals within the EU. By making labels easier to understand and aligning hazard classification rules with scientific progress, the revised CLP Regulation supports the safe use of chemical substances throughout their life cycle. Additionally, it includes new provisions on refillable chemical products, ensuring safer handling in line with circular economy goals. The changes are expected to benefit not only consumers, but also industry actors by harmonising standards and reducing legal uncertainty. The revision is part of the broader Chemicals Strategy for Sustainability under the European Green Deal, which aims to achieve a toxic-free environment and foster innovation in the sector. The European Commission has committed to providing guidance and support to ensure smooth implementation of the new rules across the single market.
