The UK government has published a new Statutory Instrument (SI) amending the Great Britain Classification, Labelling and Packaging (GB CLP) Regulation, with the measures entering into force on 21 May 2026. The amendments form part of the UK Chemicals Legislative Reform programme and introduce changes designed to modernise chemical hazard communication and align Great Britain more closely with evolving international standards under the United Nations Globally Harmonized System (GHS). According to the Cosmetic, Toiletry and Perfumery Association, the revised rules will also impact related legislation, including the GB Biocidal Products Regulation and the GB Prior Informed Consent framework. Key updates include revised hazard classification criteria, new provisions for chemical labelling, and changes to information requirements for substances and mixtures placed on the GB market. The amendments are intended to improve clarity for users, strengthen protection for human health and the environment, and ensure the regulatory framework keeps pace with scientific and technical progress. The changes are expected to affect manufacturers, importers, distributors, and downstream users across multiple sectors, including cosmetics, household products, and industrial chemicals. Companies operating in Great Britain may need to reassess classifications, update safety data sheets, revise packaging labels, and review supply chain compliance processes ahead of implementation.
