ECHA ad hoc targeted public consultations: call for comments

Deadline: 21 November 2023

The Great Britain Mandatory Classification and Labelling (GB MCL) process includes the consideration of information gathered from public consultations, conducted by HSE or international bodies such as the European Chemicals Agency (ECHA).


ECHA has announced targeted consultations on the harmonised classification and labelling (CLH) of:


  • lithium carbonate [1] lithium chloride [2] lithium hydroxide [3] (EC 209-062-5 [1]; 231-212-3 [2]; 215-183-4 [3]); CAS 554-13-2[1] 7447-41-8 [2] 1310-65-2 [3]), chemicals registered under REACH

  • methyl methacrylate; methyl 2-methylprop-2-enoate; methyl 2-methylpropenoate (EC 201-297-1; CAS 80-62-6), a chemical registered under REACH


These ad-hoc consultations seek comments on health hazard classes. The original ECHA public consultation on the lithium substances ended on the 2 October 2020 and for methyl methacrylate on the 5 July 2019.  


The detailed consultation is available 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 November 2023. 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 proposal and 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 GBCLP.GBMCL@hse.gov.uk


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.
