The Persistent Organic Pollutants (Amendment) Regulations 2026; (7 page(s), in English)

The UK is intending to amend Annex I of Regulation (EU) 2019/1021 of the European Parliament and of the Council on persistent organic pollutants ("POPs") (recast) ["the assimilated POPs Regulation"].

The proposed changes are derived from the commitments and guidance set out by the Stockholm Convention, to which the UK is a Party.

In brief, the United Kingdom is proposing:

1.    The prohibition from use, manufacture and placing on the market of five chemicals, UV-328 (a plastics and coatings additive which protects from sun damage), Dechlorane Plus (a flame retardant), Chlorpyrifos (pesticide), MCCPs (plasticizer and flame retardant), and LC-PFCAs (PFAS with a number of applications, including surface treatments and consumer products).

2.    These prohibitions are subject to some specific exemptions allowing the continued use of the substances. These exemptions align with the exemptions available under the Stockholm Convention. All exemptions are time-limited and are set out in detail in the accompanying statutory instrument.

3.    In addition to these specific exemptions, the SI will introduce an unintentional trace contaminant (UTC) level for the five POPs mentioned in point (a).

The SI will also make amendments to the UTC limits for the existing POP, PFOS, and will remove an out-dated reference to the European Committee for Standardisation (CEN) for this POP.
