Publication of GB mandatory classification and labelling (GB MCL) technical reports

A GB MCL technical report is an independent scientific evaluation of the information submitted under the stand-alone GB MCL process or as part of the EU harmonised classification and labelling process.

It sets out whether there is adequate scientific evidence to support a new or revised GB MCL of a substance and what that GB MCL should be.


The next batch of GB MCL technical reports is now available for download at the end of the GB MCL publication table (.xlsx).


These GB MCL technical reports relate to substances for which the Committee for Risk Assessment (RAC) published a RAC Opinion under Article 37(4) of EU CLP during 2022, based on information submitted under the EU CLP Regulation. The scientific information supporting the RAC Opinion is evaluated under the GB MCL system. 


At the time of publication, the classification and labelling proposed in these technical reports has not been agreed and/or adopted in Great Britain.


For information on the next steps in the process, please see our webpage on the GB MCL system.


We expect to publish our next batch of technical reports in May 2023. CLP ebulletin alerts will be issued when technical reports are published on the HSE website. 


If you have any questions or feedback on the GB MCL technical reports, please contact us at: GBCLP.GBMCL@hse.gov.uk


Journalists should contact HSE’s press office for further information.

ECHA public consultation: call for comments

Deadline: 26 May 2023

The GB MCL process includes the consideration of information gathered from public consultations, conducted by HSE or international bodies such as the ECHA.


ECHA has announced a public consultation on the following proposal for CLH:

  • 4-phenylbenzophenone (EC: 218-345-2; CAS: 2128-93-0). Chemical registered under REACH. Human health hazard classes open for commenting

Details on the consultation are 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 26 May 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 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.
