UK: United Kingdom updates POPs regulations
MARCH 2025 - ELECTRICAL AND ELECTRONICS, HARDLINES, SOFTLINES, TOYS AND CHILDREN'S PRODUCTS
The United Kingdom (UK) has published amendments to its Persistent Organic Pollutants (POPs) Regulations1,2 to align the existing regulations with the Stockholm Convention. These amendments aim to enhance environmental protection by updating concentration limits for certain pollutants, adding new substances to waste management lists, and specifying exemptions for specific uses. The amendments will take effect on 1 April 2025.
The amendments to Annex 1 of the UK POPs Regulations include updated unintentional trace contaminant (UTC) limits for hexachlorobenzene (HCB) and pentachlorophenol (PCP), revised requirements for perfluorooctanoic acid (PFOA), and the addition of dechlorane plus, methoxychlor, and UV-328. Table A summarizes these updates to Annex 1. Additionally, Annexes 4 and 5 of the POPs Regulations, which relate to the handling and management of POPs-containing waste, have also been amended accordingly.
Table A: Key changes to Annex 1
