The Minister for Social Mobility, Youth and Progression (MfSMYP), with the consent of Scottish and Welsh Ministers, has made a decision with regards to theGB mandatory classification and labelling (GB MCL)of 98 chemical substances.

The GB MCL list has been updated with these new and revised GB MCLs, under Article 37 of the GB CLP Regulation.

The Ministerial decision, with consent from the Devolved Governments, made under Article 37 of the GB CLP Regulation, is an administrative process of updating the GB MCL list with new and revised GB MCLs. Summaries of these GB MCLs have now been published in the GB CLP publication table (.xlsx), together with the entry into force date (20 October 2023) and the compliance date (20 April 2025).

The reasons for the decision were the identification of the intrinsic hazards of the 98 substances resulting from the scientific and technical assessment of the available information (as set out in the Agency Technical Reports), with no significant impacts being identified by the impact and policy assessments, as set out in the Agency Opinions.
