# UK Weighs Recycled-Plastic Certification

The UK is considering requiring independent certification of mechanically recycled plastic used to demonstrate compliance with the Plastic Packaging Tax’s 30% recycled-content threshold. HM Revenue & Customs has not decided whether to adopt the proposal, and no implementation date has been set. Separately, confirmed changes to the tax take effect on 1 April 2027. Importers and packaging suppliers serving the UK market may need to account for potential certification and traceability requirements across recyclers, polymer suppliers, and converters.

- The certification proposal is not yet mandatory; businesses should not treat it as an established requirement. Importers and packaging suppliers can review existing chain-of-custody records and supplier documentation in light of the potential proposal.
- Confirmed Plastic Packaging Tax changes take effect on **1 April 2027**. Procurement and sourcing teams can incorporate that date into planning for affected packaging purchases and supplier arrangements.
