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.

A new batch of 11 GB MCL technical reports is now available for download at the end of the GB MCL publication table.

These GB MCL technical reports relate to substances for which the Committee for Risk Assessment (RAC) published RAC Opinions under Article 37(4) of EU CLP during 2021, 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 classifications and labelling proposed in these technical reports have 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 September 2021. CLP e-Bulletin alerts will be issued when technical reports are published on the HSE website.
