ECHA public consultation: call for comments (deadline 3 September 2021)


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 a public consultation on the following proposals for harmonised classification and labelling (CLH):

● Acetone oxime (EC: 204-820-1; CAS: 127-06-0). Chemical registered under REACH.

● Multi-Walled Carbon Tubes (synthetic graphite in tubular shape) with a geometric tube diameter range ≥ 30 nm to < 3 μm and a length ≥ 5 μm and aspect ratio > 3:1, including Multi-Walled Carbon Nanotubes, MWC(N)T (EC: -; CAS: -).

● Propyl 3,4,5-trihydroxybenzoate (EC: 204-498-2; CAS: 121-79-9). Chemical registered under REACH.

● S-metolachlor (ISO) (EC: -; CAS: 87392-12-9). Pesticide active substance.

● Sulfur (EC: 231-722-6; CAS: 7704-34-9). Pesticide active substance.

The details can be viewed here.

UK-based businesses with an interest in the proposals are strongly encouraged to share any relevant information.

Scientific and technical information should be submitted directly to ECHA using their commenting webform by 3 September 2021. 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 any of 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

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.
