"The European Commission make draft Commission Delegated Regulation amends Regulation (EU) 2019/1021 on persistent organic pollutants to include medium-chain chlorinated paraffins (MCCPs) in Annex I, following Decision SC-12/10 adopted under the Stockholm Convention. The aim is to strengthen protection of human health and the environment by prohibiting or restricting the manufacture, placing on the market and use of MCCPs, while allowing narrowly defined exemptions where immediate substitution is not technically feasible.
- The proposal reflects decisions taken at the twelfth Conference of the Parties (28 April–9 May 2025) and scientific opinions issued by the European Chemicals Agency (ECHA) and its Risk Assessment and Socio-Economic Analysis Committees. A concentration limit of 0.1% by weight (1000 mg/kg) is introduced for MCCPs as unintentional trace contaminants to prevent deliberate use.
- Time-limited exemptions are granted for specific uses considered critical, including heavy-duty metalworking fluids (until 31 December 2036), spare parts for vehicles, machinery, medical and electronic equipment, and aerospace and defence applications (generally until end of service life or 31 December 2041). Additional temporary exemptions apply to medical device cables, adhesives, sealants, paints, coatings and specialised defence applications, typically for a period of five years, with the possibility of extension.
- The proposal requires that emissions to the environment and worker exposure are minimised wherever exemptions apply. It also introduces transparency obligations, requiring manufacturers, importers and suppliers to disclose MCCP content and risk management measures in safety data sheets. "
