Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, pursuant to the Answer of 5 November 2025 to question 86529, whether divergence between EU and GB mandatory hazard classifications for the same substance will change under HSE proposals for changing GB Classification, Labelling and Packaging.

From 23 June to 18 August 2025, the Health and Safety Executive (HSE) consulted on proposals to reform three pieces of chemicals legislation: Great Britain Biocidal Products Regulation (GB BPR); Great Britain Classification, Labelling and Packaging (GB CLP); and Great Britain Prior Informed Consent for the export and import of hazardous chemicals (GB PIC).

The reform proposals suggest procedural changes to how the GB Classification system operates but do not propose changes to the underlying scientific criteria used for classifying and labelling chemicals. These criteria are set out in Annexes I and II to the GB Classification, Labelling and Packaging Regulation (known as the GB CLP Regulation).

The final proposals for GB CLP will be confirmed as part of HSE’s response to the Chemicals Legislative Reform Proposals consultation. It is expected to be published in early 2026 subject to Ministerial approval.
