The next batch of GB mandatory classification and labelling (GB MCL) Agency Opinions are now available for download A GB MCL Agency Opinion formally proposes the GB MCL for chemical substances, based on the scientific and technical assessment of the scientific data in line with the GB CLP Regulation, together with an assessment of the policy and socio-economic impacts on the UK. It sets out whether there is adequate scientific evidence to support a new or revised GB MCL of a substance and what the potential impact of the proposed GB MCL may be. Download the Agency Opinions These GB MCL Agency Opinions relate to substances for which HSE (as the GB CLP Agency) published an Agency Technical Report under Article 37 of the GB CLP Regulation in 2023. At the time of publication, the classification and labelling proposed in this Agency Opinion has not been agreed and/or adopted in GB. Visit HSEâs website for information on the next steps in the process We expect to publish our next batch of Agency Opinions in March 2025. CLP ebulletin alerts will be issued when Agency Opinions are published on the HSE website. If you have any questions or feedback on the GB MCL Agency Opinions, please contact us at: [email protected] Journalists should contact HSEâs press office for further information.

View the consultations on the ECHA website.
UK-based businesses with an interest in the proposal are strongly encouraged to share any relevant information. Scientific and technical information should be submitted directly to ECHA using their commenting webform by 21 March 2025 or 28 March 2025. Comments will be published on ECHA's website. If your business is affected by the GB CLP Regulation, please also consider if you are likely to be affected by the classification and labelling proposals. Let us know at an early stage if you anticipate any significant impacts or benefits. Information on wider policy and impact considerations can be submitted to HSE at [email protected]. Under the GB CLP Regulation, HSE will consider all published opinions of the Committee of Risk Assessment of ECHA (RAC) before publishing its own Agency Technical Reports and Agency Opinions, so any information you provide will be important in any final GB MCL decision.  More information on the new GB MCL system is available on the HSE website. |
