Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, which chemical substances have received EU Harmonised Classification and GB Mandatory Classification since 1 January 2021 by (a) chemical name, (b) European Community number, (c) CAS Registry Number, (d) EU harmonised classification (i) hazard class and category code and (ii) hazard statement code and (e) GB Mandatory Classification (i) Hazard class and category code, (ii) Hazard statement code and (iii) date of entry into legal effect.

Since 1 January 2021, the Health and Safety Executive (HSE), as the regulator, has acted as the Agency for the assimilated Regulation (EC) No. 1272/2008 on classification, labelling and packaging of substances and mixtures as amended in Great Britain (or the GB CLP Regulation).

HSE is responsible for the GB mandatory classification and labelling system (GB MCL) and for updating the GB MCL List on the HSE website with new/revised or deleted entries in accordance with a timetable set out in UK law. The GB MCL List entries provide information on chemical substances that have GB MCLs including: a) chemical name, (b) European Community number, (c) CAS Registry Number, (e) GB Mandatory Classification and Labelling (i) Hazard class and category code, (ii) Hazard statement code and (iii) date of entry into legal effect.

The GB MCL List does not include information on the EU harmonised classification and labelling, hazard class and category code and hazard statement code for these chemical substances. This information is available on the European Chemicals Agency website in the unofficial ‘Table of harmonised entries containing all updates to the harmonised classification and labelling of hazardous substances, available in Table 3 of Annex VI to the EU CLP Regulation’.

The GB MCL List includes 4430 entries. Since 1 January 2021, 206 chemical substances have received GB MCLs, following a recommendation by HSE as the Agency and a Ministerial Decision made with the consent of Scottish and Welsh Ministers. The GB MCL entries for the 206 entries, including the requested information, are published in the GB MCL List on the HSE website – please see https://www.hse.gov.uk/chemical-classification/classification/mcl-list.htm.
