View the consultation 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 12May 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 classification and labelling proposals 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 systemis available on the HSE website. |
