SG 43/23

The EU has issued a revision to its Regulation on classification, labeling and packaging of substances and mixtures (CLP Regulation). The amendment will enter into force on April 20, 2023.

In March 2022, the European Union (EU) issued Commission Delegation Regulation (EU) 2023/707 to revise Regulation (EU) No. 1272/2008 on classification, labeling and packaging of substances and mixtures (CLP Regulation, consolidated version to December 2022).

The latest amendment contains several important changes to the CLP Regulation. It:

  • Adds new requirements to Annex I ‘Classification and labeling requirements for hazardous substances and mixtures’ for the classification, assessment and labeling of substances and mixtures that are:
    • Endocrine disruptors (ED)
    • Persistent, bioaccumulative and toxic (PBT) or very persistent or very bioaccumulative (vPvB)
    • Persistent, mobile and toxic (PMT) and very persistent, very mobile (vPvM)
  • Revises Annex II ‘Special rules for labeling and packaging of certain substances and mixtures’ in relation to the concentration of a substance classified as an ED for human health category 2 or environmental category 2
  • Amends hazard statements falling under Annex III ‘List of hazard statements, supplemental hazard information and supplementary label elements’
  • Inserts new hazard codes and category codes for ED, PBT, vPvB, PMT and vPvM to Annex VI ‘Harmonized classification and labeling for certain hazardous substances’

Highlights of the aforementioned new requirements for Annex I to the CLP Regulation are summarized in Table 1.
