The UK Plastic Packaging Tax (PPT) has quietly become one of the most predictable — and yet most frequently underestimated — compliance costs for importers and domestic manufacturers. Since it came into force on 1 April 2022, the tax has risen every year in line with inflation, expanded its scope through Budget announcements, and is now on the brink of its most significant operational change yet: mandatory third-party certification for recycled-content claims, plus a mass-balance approach for chemically recycled plastic.
If you import or manufacture plastic packaging in the UK, the 2026 rate change and the 2027 rules will affect your cost base, your supplier conversations, and your evidence trail. This article explains where the tax stands today, what changes on 1 April 2027, and how importers should prepare before the new certification regime arrives.

What Is the Plastic Packaging Tax?
The Plastic Packaging Tax applies to plastic packaging components manufactured in, or imported into, the UK that contain less than 30% recycled plastic. It is an environmental tax designed to encourage the use of recycled material by making virgin-heavy packaging more expensive.
Key points from the start:
- It applies to filled and unfilled plastic packaging components.
- It is payable by the manufacturer or importer, not the end brand owner.
- Cost usually flows through the supply chain and appears as a line item on supplier invoices.
- All liable businesses must register with HMRC and submit quarterly returns.
- The de minimis threshold is 10 tonnes of finished plastic packaging components in any rolling 12-month period.
The 30% threshold has not changed since launch. What has changed — and keeps changing — is the rate, the record-keeping burden, and the evidence required to claim exemption.
The 2026 Rate Change: £228.82 Per Tonne
From 1 April 2026, the Plastic Packaging Tax rate increased to £228.82 per tonne. That is up from £223.69 per tonne in 2025, a rise of roughly 2.3% in line with CPI.
| Year | PPT Rate per Tonne |
|---|---|
| 2022 | £200.00 |
| 2023 | £210.82 |
| 2024 | £217.85 |
| 2025 | £223.69 |
| 2026 | £228.82 |
The annual uplift is now baked into the regime. For businesses that move hundreds or thousands of tonnes of plastic packaging each year, even a small percentage increase adds up quickly. A company importing 500 tonnes of non-exempt plastic packaging in 2026 will pay roughly £114,410 in PPT — about £2,565 more than in 2025.
Because suppliers often pass the tax through as a separate invoice line, procurement teams sometimes treat PPT as a supplier charge rather than a direct tax. It is both. Understanding the calculation protects you from being double-charged or from accepting unverified recycled-content claims.
Registration and the 10-Tonne Threshold
You must register for PPT within 30 days of crossing the 10-tonne threshold of finished plastic packaging components in any rolling 12-month period. The threshold applies regardless of whether you expect to pay any tax.
That last point catches people out. Even if all your packaging contains more than 30% recycled plastic and you owe no tax, you must still register once you exceed 10 tonnes in a 12-month window. The logic is that HMRC wants visibility over the market and a way to audit exemption claims.
Registration is done through HMRC. Once registered, you must:
- Submit quarterly PPT returns.
- Keep records of all plastic packaging handled, including exempt and non-exempt categories.
- Retain evidence of recycled content where exemption is claimed.
- Pay any tax due by the quarterly deadline.
The 10-tonne threshold has not changed since 2022, but the evidence required to support exemption claims is about to tighten significantly.
How the Tax Hits Importers
Importers face the same liability as UK manufacturers, but with added complexity. If you import plastic packaging — whether filled, unfilled, or as part of a finished product — you are the importer of record and therefore responsible for PPT if the packaging falls below the 30% recycled threshold. That liability sits alongside normal customs controls, so teams should align it with the data discipline already needed for UK customs clearance.
Practical implications for importers include:
- Cost visibility: PPT often appears as a pass-through on your supplier invoice. You need to verify the basis of the calculation and the recycled-content claim behind it.
- Supplier evidence: If your supplier claims 30%+ recycled content to avoid PPT, you need documentation that will stand up to HMRC scrutiny.
- Classification detail: Plastic packaging comes in many forms — bottles, films, trays, shrink wrap, caps, labels. Each component must be considered separately.
- Multipack exposure: Shrink-wrapped multipacks are a common pain point. A 24-bottle multipack might use 18–24 grams of film. At scale, that can push annual PPT bills into six figures for fast-moving consumer goods importers.
- Customs interaction: PPT is separate from customs duty and VAT, but it sits alongside them. Importers already managing HS codes, origin, and duty rates must add recycled-content verification to their workflow.
The tax also creates friction in supplier negotiations. A supplier quoting “PPT included” without evidence of recycled content may simply be absorbing the tax themselves, or passing it on. Either way, the importer remains liable if the paperwork is wrong.
The 2027 Changes: Mass Balance, Pre-Consumer Waste, and Mandatory Certification
The most important developments are not the 2026 rate change. They are the changes announced at Budget 2025 that take effect on 1 April 2027.
Mass Balance Approach for Chemical Recycling
From April 2027, chemically recycled plastic will count toward the 30% recycled content threshold, but only if it is certified under an approved mass balance approach (MBA). This is significant because chemical recycling produces plastic that is chemically identical to virgin material and cannot be physically traced back to recycled feedstock. A mass balance system allows recycled content to be attributed across a production process based on verified inputs.
For importers, this means:
- You can no longer rely on a supplier statement alone for chemically recycled content.
- You will need evidence from an approved certification scheme.
- The paperwork must follow the mass balance chain of custody from recycler to converter to finished packaging.
Removal of Pre-Consumer Waste
Also from April 2027, pre-consumer plastic waste will no longer count as recycled plastic for PPT purposes. Only post-consumer recycled plastic will qualify toward the 30% threshold.
Pre-consumer waste is scrap or offcuts generated during manufacturing, before the product reaches the consumer. It has historically counted as recycled content under PPT. Removing it tightens the definition and aligns the UK regime more closely with consumer-facing sustainability expectations. For manufacturers who relied on in-house regrind or industrial scrap to hit the 30% mark, this is a material change.
Mandatory Third-Party Certification
Perhaps the biggest shift is the introduction of mandatory third-party certification for recycled-content claims. The current rules allow businesses to self-certify recycled content with supporting evidence. From 2027, both mechanically and chemically recycled plastic claims will need certification from an approved third-party scheme.
HMRC ran a consultation on mandatory certification for mechanically recycled plastic from 18 May 2026 to 10 August 2026. The consultation was driven by industry concerns about fraudulent or inaccurate recycled-content claims, particularly for imported packaging where verification is harder.
What this means in practice:
- Suppliers will need to obtain certification for their recycled plastic claims.
- Importers will need to collect and retain that certification.
- Claims without approved certification will not support the 30% exemption.
- The compliance burden moves upstream, but the liability still rests with the importer or manufacturer.
The 2026 Consultation and What It Signals
The HMRC consultation that closed on 10 August 2026 asked for views on:
- The prevalence of fraud and error in recycled-content claims.
- The impact of mandatory certification on businesses.
- How certification should operate.
- Implementation timing.
The direction of travel is clear. HMRC wants a more robust, auditable system for recycled-content claims. The consultation outcome is expected to shape the detailed rules for mechanical recycling certification, while the chemical recycling and pre-consumer waste changes are already locked in for April 2027.
For businesses that have not yet reviewed their supplier evidence, the consultation deadline should be treated as a wake-up call. The era of informal recycled-content declarations is ending.
Practical Steps for Importers
Here is a practical checklist for importers preparing for the 2026 rate and the 2027 rules:
-
Map your plastic packaging exposure. Identify every plastic packaging component you import, by type, weight, and supplier. Do not rely on supplier estimates.
-
Verify recycled-content claims now. Ask suppliers for existing evidence of recycled content. If they cannot provide robust documentation, assume the 30% exemption may not hold under the 2027 certification rules.
-
Check whether pre-consumer waste is part of the claim. If a supplier currently hits 30% using industrial scrap or in-house regrind, that path closes in April 2027.
-
Understand mass balance if you use chemically recycled plastic. If your supply chain includes chemical recycling, start conversations now about approved certification schemes and chain-of-custody documentation.
-
Review PPT costs in your pricing. With the rate now £228.82 per tonne, update landed-cost models and supplier negotiations. Verify that pass-through charges are correctly calculated. Our landed-cost calculation guide shows where to place packaging tax alongside freight, duty, VAT and broker fees.
-
Register if you are close to the threshold. If your rolling 12-month tonnage is approaching 10 tonnes, register before you cross it. Registration is required even if all your packaging is exempt.
-
Prepare for quarterly returns. Ensure your record-keeping captures weight, recycled content, exemption basis, and supporting evidence by component.
-
Watch for the consultation outcome. HMRC will publish guidance on the certification regime for mechanical recycling. Build time into your compliance calendar to adapt.
Looking Ahead: More Than a Rate Rise
The 2026 Plastic Packaging Tax rate change is important for budgeting, but it is not the main story. The real shift is the move from self-certified recycled-content claims to a third-party certification system, combined with tighter definitions of what counts as recycled plastic.
Importers who treat PPT as a static line item risk being caught out when the 2027 rules take effect. Those who audit their packaging exposure, verify supplier claims, and align their record-keeping with the new certification requirements will be in a much stronger position — both for compliance and for cost control.
The Plastic Packaging Tax is becoming more like other HMRC regimes: precise, evidence-based, and increasingly unforgiving of weak documentation. The businesses that adapt early will avoid the disruption that usually follows a deadline.
