The UK Plastic Packaging Tax has been in force since April 2022 and the rate has increased since introduction. As of April 2024 it sits at £217.85 per tonne of plastic packaging that doesn't meet the 30% recycled content threshold. Most businesses importing or manufacturing plastic packaging have a real liability here, and a meaningful proportion haven't properly assessed whether they do.
What the tax applies to and the 30% threshold that eliminates the liability
PPT applies to plastic packaging components: products made predominantly of plastic by weight, designed for use in supplying or packaging goods. The scope is broad: bottles, containers, bags, pouches, trays, pots, film, wrapping, caps, lids, closures, and composite items where plastic is the majority material.
The key exemption is the 30% recycled content threshold. A plastic packaging component containing at least 30% recycled plastic content is exempt from the tax, regardless of total plastic content or plastic type. That exemption drives the practical compliance strategy for most businesses: not eliminating plastic packaging, but switching to components that meet the threshold.
The tax applies to UK manufacturers of finished plastic packaging components and to UK importers, whether importing empty components, packaging pre-filled with product, or packaging materials for their own manufacturing. If you import goods that arrive in plastic packaging, your position needs assessment.
The 10-tonne threshold provides a de minimis: businesses manufacturing or importing less than 10 tonnes of plastic packaging annually have no tax liability, though registration requirements may still apply close to the threshold.
The per-unit impact is real at scale
At £217.85 per tonne, the tax on a single item looks trivial. A 20-gram plastic tray carries a PPT liability of around 0.4p. The calculation changes quickly at volume.
A business importing 50 tonnes of non-exempt plastic packaging annually faces a liability of approximately £10,900. At 100 tonnes, roughly £21,800 per year. These costs should be visible in your packaging economics and reflected in your supplier decisions.
The more useful framing: what would it cost to switch your highest-volume non-exempt items to compliant 30% recycled content alternatives, and how does that premium compare to the PPT saving?
Where the economics of recycled content often work
RPET (recycled PET from collected bottles) and rHDPE (recycled high-density polyethylene) are the most widely available options. Most plastic packaging manufacturers now offer recycled content variants with manageable lead times.
Recycled plastic content typically costs 5-15% more per tonne than virgin equivalent, depending on material type and market conditions. At £217.85 per tonne PPT rate, the premium for recycled content often costs less than the tax saving, particularly for higher-density packaging items.
The switch isn't always straightforward. Some recycled content performs slightly differently in processing, with different melt flow characteristics and tolerances. Your manufacturer needs to confirm compatibility with existing tooling before you commit to a specification change.
You also need to evidence compliance. Certificates of recycled content from your supplier, retained in your records, form your compliance documentation. HMRC specifies what adequate evidence looks like. If your supplier can't provide documentation that meets that standard, the exemption won't hold up to scrutiny.
How PPT and EPR interact
PPT and EPR are separate obligations under different legislation, administered by different bodies: HMRC for PPT, the Environment Agency for EPR. Both apply in parallel with their own reporting requirements and fee structures.
The underlying data largely overlaps: weight, type and composition of plastic packaging supplied or imported. If you're tracking packaging data for EPR, much of the groundwork for PPT reporting is already done.
If you're approaching both together, build a single packaging inventory capturing material type, recycled content percentage, weight per unit and annual volume. That data serves both frameworks and clarifies where your highest-cost exposures sit.
