The purpose of this draft proposal for a Commission Delegated Regulation under Article 53(1) of the CLP Regulation is to amend Part 1, section 1.1.3, of Annex VI to introduce notes clarifying the application of certain harmonised classifications introduced pursuant to Article 37(7) of the CLP Regulation, in particular as regards the classification of mixtures containing substances covered by the same Annex VI entry for ED, PBT and vPvB hazard classes and differentiations, including through additivity rules applicable to specific groups of substances. This notification should be read in conjunction with the complementary notification concerning the harmonised classification and labelling of certain substances (26 pages including Annex, in English), which establishes the underlying harmonised classifications for approximately 107 substances identified as ED, PBT or vPvB under REACH, the Plant Protection Products Regulation and the Biocidal Products Regulation, to which the notes introduced by this act apply.
