HM Revenue & Customs (HMRC) has released preliminary guidance detailing how chemically recycled plastics must be accounted for under the UK Plastic Packaging Tax (PPT). From 1 April 2027, chemically recycled content will only contribute towards the 30% recycled threshold if it is tracked through a qualifying, certified mass-balance supply chain.
Currently, the PPT applies a levy to plastic packaging manufactured in or imported into the UK that contains less than 30% recycled plastic. While mechanically recycled materials have straightforward traceability, chemical recycling—which breaks down polymers into molecular feedstocks—requires a mass-balance approach to attribute recycled content to final products. HMRC’s new minimum certification requirements aim to standardise this process, ensuring environmental claims are verifiable and preventing double-counting.
For UK packaging converters and waste management firms, this announcement provides long-overdue regulatory clarity. It establishes a clear timeline to adapt procurement strategies and audit trails before the 2027 deadline. However, it also means businesses must prepare for more rigorous third-party auditing and chain-of-custody documentation.
Implications for UK–Türkiye Trade
This regulatory update has significant ramifications for Turkish recyclers exporting to the UK. As UK converters look to secure compliant recycled polymers, Turkish suppliers must ensure their certification schemes align with HMRC’s approved frameworks. While mechanical recycling remains the dominant route for Turkish exporters of rPET and rHDPE, those investing in chemical recycling technologies must prepare for strict mass-balance audits to remain competitive in the UK market. Conversely, the clear rules may boost demand for certified imports that can help UK buyers avoid the PPT.
Practical Takeaway
Packaging converters and importers should immediately review their supply chains and consult with their polymer suppliers. Ensuring that any chemically recycled resins purchased are certified under recognised schemes, such as ISCC PLUS, will be essential to avoid unexpected PPT liabilities when the rules take effect in 2027.
