THE GB MANDATORY CLASSIFICATION PROCESS

This process for generating new MCLs is similar to the one in place in the EU, with the HSE replacing ECHA as the Competent Authority (although there are actually two processes at ECHA which may give rise to a new Harmonised Classification, that is CoRAP and the CLH process).

Details here: https://www.hse.gov.uk/chemical-classification/new-revised-proposal.htm

However, GB-CLP also includes a review process for all EU Harmonised Classifications, to decide whether or not to adopt them into GB-CLP.

UPDATING EXISTING MCLS

THE CURRENT OFFICIAL GB MANDATORY CLASSIFICATION LIST

This is available on the HSE web page here, for download in excel format:

https://www.hse.gov.uk/chemical-classification/classification/harmonised-classification-self-classification.htm

(it can also be downloaded from other MCL pages).

However, this spreadsheet includes the 14th and 15th ATPs as well as the current legal version, the 13th ATP, without any dates of implementation.

This is version 1.1, which has been updated slightly (published in July 2021) to take into account some errors which have been found.  There is no date of application given in the relevant columns, but a new page has been included clarifying the dates of application.

CHANGES DUE TO BE IMPLEMENTED

None that we are aware of.

UNOFFICIAL VERSIONS OF GB-MCL

We have produced a version of the current GB official spreadsheet, with all of the implementation dates included: GB MCL to 15th ATP 01-03-2022 TTE v1.1 25-01-2021

We have also made our own individual versions for you, as an interim measure until the HSE can get their own versions produced:

GB MCL to 13th ATP, in effect 31st December 2020, v1, 25-01-2021

GB MCL to 14th ATP, in effect 1st October 2021, v1, 25-01-2021

GB MCL to 15th ATP, in effect 1st March 2022, v1.1, 25-01-2021

CHANGES IN PIPELINE

  • A total of 82 possible GB-MCLs have been brought into GB from EU legislation such as Plant Protection Products, Biocides etc.
  • One of these is out for comment as a possible Harmonised Classification, see
  • It’s possible that new EU HCs may be brought into GB MCL.  There are currently (July 2021) no signs of this.
