Are you ready for the new CLP hazard classes for ED?

With the latest consolidated version of the CLP Regulation (as of 31 July 2023), new EUH statements and hazard classes for ED are introduced.

New EUH-statements and new hazard classes for ED human health/environment are included in the latest revision of the CLP Regulation. Substances and mixtures shall be classified in accordance with the criteria laid down in the CLP. Transition periods are available to comply with the new hazard classes. 


The public consultation for the revision of the CLP regulation ended the 3rd March 2023. As of 31st July 2023, the latest consolidated version of the CLP Regulation is available which sets out new hazard classes and criteria for the classification, labelling and packaging of substances and mixtures. It applies to all chemical substances and mixtures placed on the EU market under REACH. It also applies to active substances in biocidal products and plant protection products, which are normally prioritised for harmonised classification in the EU.

There are two hazard categories for Endocrine Disruptor (ED) and corresponding EUH-statements: 


  •    ED HH/ENV Cat. 1: Known or presumed endocrine disruptors for human health/environment; EUH380/430: May cause endocrine disruptions in humans/the environment
  •     ED HH/ENV Cat. 2: Suspected endocrine disruptors for human health/the environment; EUH381/431: Suspected of causing endocrine disruptions in humans/the environment
The generic concentration limits for mixtures are ≥ 0.1% for Cat. 1 and ≥ 1% for Cat. 2. 
The new rules are in force from 20 April 2023 but there are transition periods for new/existing substances and mixtures:


  •    New substances: 01/05/2025
  •    Existing substances which were placed on the market before 01/05/2025: 01/11/2026 
  •    New mixtures: 01/05/2026
  •    Existing mixtures which were placed on the market before 01/05/2026: 01/05/2028

Besides the new hazard classes for ED, other classes were also introduced for PBT (persistent, bioaccumulative, toxic), vPvB (very persistent, very bioaccumulative) and PMT (persistent, mobile, toxic), vPvM (very persistent, very mobile).
