This is the 13th adaptation to technical and scientific progress (ATP).

It amends the CLP by adding Echa’s Risk Assessment Committee’s (Rac) 2017 opinions on harmonised classification of several substances to Annex VI. The ATP includes 18 updated and 16 new entries.

Substances added to the list include the preservative methylisothiazolinone (MIT), which has been assigned a 15ppm specific concentration limit. This is significantly lower than the 0.1% concentration limit used for general category 1A skin sensitisers.

The paint and cleaning products industry has voiced concern that the classification, and an expected restriction under the biocidal products Regulation (BPR) would push MIT off the market as the substance is no longer effective at 15ppm concentration.

The 13th ATP was published in the EU Official Journal on 4 October. It will enter into force 20 days after publication and the changes will apply from 1 May 2020.

The 11th ATP was published in May and added the chemical names of substances subject to harmonised classification and labelling listed in Table 3 of Annex VI in all languages.

The ATPs are not necessarily published and adopted in order due to time required for drafting, discussing and agreeing a legal act. The 12th ATP constitutes the alignment of CLP to revision numbers 6 and 7 of the Globally Harmonised System for the classification and labelling of chemicals. It received a positive vote during the September REACH Committee meeting and is now in the process of adoption.
