A GB MCL technical report is an independent scientific evaluation of the information submitted under the stand-alone GB MCL process or as part of the EU harmonised classification and labelling process. It sets out whether there is adequate scientific evidence to support a new or revised GB MCL of a substance and what that GB MCL should be. The next batch of GB MCL technical reports is now available for download at the end of the GB MCL publication table (.xlsx). These GB MCL technical reports relate to substances for which the Committee for Risk Assessment (RAC) published a RAC Opinion under Article 37(4) of EU CLP during 2023, based on information submitted under the EU CLP Regulation. The scientific information supporting the RAC Opinion is evaluated under the GB MCL system. At the time of publication, the classification and labelling proposed in these technical reports has not been agreed and/or adopted in Great Britain. For information on the next steps in the process, please see our webpage on the GB MCL system. We expect to publish our next batch of technical reports in January 2024. CLP ebulletin alerts will be issued when technical reports are published on the HSE website. If you have any questions or feedback on the GB MCL technical reports, please contact us at: GBCLP.GBMCL@hse.gov.uk Journalists should contact HSEs press office for further information. A GB MCL Agency Opinion formally proposes the GB mandatory classification and labelling 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. The next batch of 4 GB MCL Agency Opinions are now available for download in the GB MCL publication table (.xlsx). 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 December 2022. At the time of publication, the classification and labelling proposed in this Agency Opinion has not been agreed and/or adopted in Great Britain. For information on the next steps in the process, please see our webpage on the GB MCL system. We expect to publish our next batch of Agency Opinions in February 2024. CLP ebulletin alerts will be issued when Agency Opinions are published on the HSE website.
