What Is the Plastic Packaging Tax?
The Plastic Packaging Tax (PPT) is a UK environmental tax introduced on 1 April 2022 to encourage the use of recycled plastic in packaging. It is administered by HMRC — not DEFRA — and operates as a standalone tax entirely separate from the Extended Producer Responsibility (EPR) scheme for packaging.
The tax applies to plastic packaging components that are manufactured in or imported to the UK and that do not contain at least 30% recycled plastic content by weight. If your plastic packaging meets or exceeds that 30% threshold, it is exempt from the tax. If it falls below 30%, you owe PPT on the full weight of the component — not just the shortfall.
The policy rationale is straightforward. By making virgin plastic packaging more expensive, the government creates a financial incentive for businesses to incorporate recycled material into their supply chains. This in turn increases demand for recycled plastic feedstock, supports UK reprocessing infrastructure, and reduces the amount of virgin plastic entering the economy.
Key distinction: PPT is a tax, not a fee
Unlike EPR fees (which are paid to a scheme administrator to fund packaging waste management), PPT is a tax paid directly to HMRC. It is reported on quarterly tax returns, falls under HMRC compliance and enforcement, and carries the same legal weight as other UK taxes. Penalties for non-compliance are governed by HMRC's standard penalty regime, including interest on late payments and potential criminal prosecution for fraud. For a full breakdown of enforcement actions and financial consequences across both PPT and EPR, see our guide to packaging compliance penalties and fines.
Since its introduction, the Plastic Packaging Tax has generated over £700 million in revenue for the Treasury and has driven measurable increases in recycled content across UK plastic packaging. Industry data suggests average recycled content in obligated packaging rose from around 10% in 2021 to approximately 20% by 2025 — significant progress, though still below the 30% exemption threshold for many producers.
For businesses handling plastic packaging, understanding PPT is no longer optional. It represents a direct cost that appears on your tax bill, and the rate increases every year. Getting it right — or better, engineering it out entirely — requires a clear understanding of the rules, the thresholds, and the strategies available to you.
Current Rate & Rate History
The Plastic Packaging Tax rate increases annually in line with the Consumer Price Index (CPI). This means the tax becomes more expensive every year, even if your plastic consumption remains unchanged. Planning solely on today's rate will underestimate your future liability.
When the tax launched in April 2022, the rate was set at £200.00 per tonne. It remained at this level through to March 2024. The rate then rose to £210.82 for the 2024–25 period, increased again to £217.85 for 2025–26, and from 1 April 2026 stands at £228.82 per tonne.
To put these numbers in perspective: a business handling 100 tonnes of non-exempt plastic packaging now faces an annual PPT bill of £22,882 — up from £20,000 when the tax launched, an increase of over 14% in four years. For larger producers handling thousands of tonnes, the cumulative increase runs into the hundreds of thousands.
Budget your PPT at future rates, not today's
Assuming CPI inflation of 3–4% per year, the PPT rate could exceed £250 per tonne by 2028 and approach £280 per tonne by 2030. If you are evaluating the business case for increasing recycled content, model your savings at projected future rates rather than today's rate. The return on investment for reformulation only improves over time.
Who Must Register?
You are required to register with HMRC for the Plastic Packaging Tax if, in any rolling 12-month period, you have manufactured or imported 10 or more tonnes of plastic packaging components. You must also register if you reasonably expect to exceed 10 tonnes in the next 30 days.
The 10-tonne threshold is a registration threshold, not an exemption threshold. This is a critical distinction that catches many businesses out. Even if you are below 10 tonnes, you should be tracking your volumes because you must register as soon as you cross the threshold — or as soon as you expect to cross it. Failing to register on time is itself a compliance failure that can attract penalties.
Who is in scope?
- UK manufacturers of plastic packaging components — whether they use those components themselves or sell them to other businesses
- Importers of plastic packaging components — including packaging that arrives already filled with product (for example, bottles of water imported from overseas)
- Importers of empty packaging — such as rolls of film, stacks of trays, or pallets of bottles brought in for filling in the UK
- Business-to-business and business-to-consumer packaging are both in scope
Notably, PPT does not distinguish by company size, turnover, or sector in the way that EPR does. A small importer bringing in 10 tonnes of plastic packaging has the same registration obligation as a multinational manufacturer handling 10,000 tonnes. The only difference is the scale of the tax bill.
Do not confuse PPT thresholds with EPR thresholds
EPR obligations are triggered by turnover (£1 million+ for small producers, £2 million+ for large) and overall packaging tonnage (25 or 50 tonnes across all materials). PPT has a single, simple threshold: 10 tonnes of plastic packaging components in any 12-month period, regardless of turnover. You could be a £500,000-turnover business and still be required to register for PPT.
What Counts as Plastic Packaging?
Under PPT, a packaging component is classified as "plastic" if plastic is the single heaviest material by weight in that component. This is a weight-by-weight comparison of each individual material in the component — not the packaging system as a whole.
Common examples of plastic packaging that falls within PPT scope include:
- PET bottles and containers — drinks bottles, food containers, cosmetics packaging
- Polystyrene trays — EPS meat trays, protective moulded inserts
- Flexible film and wrapping — shrink wrap, stretch film, flow-wrap, bag-in-box liners
- Blister packs — pharmaceutical and consumer electronics packaging
- Plastic crates, pallets, and drums — reusable transit packaging (though some exemptions apply for certain reusable formats)
- Bubble wrap and air pillows — void-fill and protective packaging
- Plastic tubes and cartridges — toothpaste tubes, silicone cartridges, adhesive packaging
- Carrier bags — single-use and bags for life
Multi-material components
For multi-material packaging components, the classification depends on which single material is heaviest. A drinks carton that contains more paperboard by weight than plastic (even if it also contains an aluminium layer) is classified as paper/card, not plastic — and is outside PPT scope. However, a laminated pouch where the plastic layers outweigh the aluminium and paper layers combined is classified as plastic and falls within scope.
Bio-based and compostable plastics are in scope
A common misconception is that "bio-plastics" or "compostable plastics" are exempt from PPT. They are not. HMRC defines plastic as any material that contains a polymer as a primary structural component, regardless of whether it is derived from fossil or bio-based feedstock. PLA (polylactic acid), bio-PE, bio-PET, and all compostable plastics count as plastic for PPT purposes. The only thing that matters for exemption is the recycled content threshold.
What is not plastic packaging?
Certain items are excluded from PPT even though they contain plastic. These include:
- Items that are not packaging — plastic products that serve a primary function other than containing, protecting, or presenting goods (for example, a plastic storage box sold as a product in its own right)
- Immediate packaging of licensed medicinal products — blister packs and vials for licensed human medicines are exempt
- Transport packaging permanently bonded to the goods — specific, narrow exemptions exist for certain permanently affixed components
- Packaging with 30%+ recycled content — this is not an exclusion from scope, but an exemption from the tax itself (the packaging still needs to be reported)
The 30% Recycled Content Threshold
The central mechanism of the Plastic Packaging Tax is the 30% recycled content threshold. If a plastic packaging component contains at least 30% recycled plastic by weight, it is exempt from the tax. If it falls below 30%, the tax is charged on the full weight of the component — not just the virgin plastic portion.
This all-or-nothing structure is deliberate. It creates a clear target for manufacturers and importers: hit 30% recycled content and pay nothing; miss it and pay the full rate on every kilogram. There is no sliding scale or partial credit for, say, 20% recycled content. At 29.9%, you pay the full tax. At 30.0%, you pay nothing.
What counts as "recycled"?
Both mechanical recycling and chemical recycling count towards the 30% threshold. Mechanical recycling involves physically processing waste plastic (washing, shredding, melting, re-pelletising) into secondary raw material. Chemical recycling breaks plastic down to its molecular building blocks through processes like pyrolysis or depolymerisation, then rebuilds new polymer from those building blocks.
The recycled content must be post-consumer or post-industrial waste plastic that has been through a recycling process. Pre-consumer manufacturing scrap that is reused within the same production process does not count. The intent is to incentivise the use of genuinely recycled material drawn from the waste stream, not to reward efficient manufacturing.
Proving your recycled content
HMRC requires you to hold evidence that your plastic packaging meets the 30% threshold. This evidence typically comes from your supply chain and may include:
- Supplier declarations or certificates confirming recycled content percentage
- Mass balance chain-of-custody certificates (particularly for chemical recycling)
- Independent third-party test reports
- Purchase records for recycled resin linked to specific production batches
- Internal quality control records tracking recycled content through manufacturing
You do not need to submit this evidence with every quarterly return, but you must be able to produce it on request. HMRC can and does conduct compliance checks where they ask to see the documentation supporting your recycled content claims. Records should be maintained for at least 6 years.
Get your supplier evidence in order now
The most common compliance issue with PPT exemptions is inadequate evidence. Many businesses claim the 30% exemption based on verbal assurances from suppliers, only to find they cannot produce documentary evidence when HMRC asks. Build recycled content certification into your procurement contracts and request written declarations as standard practice. It is far easier to set up good evidence procedures now than to reconstruct them under audit pressure later.
PPT vs EPR: Understanding Both Obligations
One of the most frequent questions we hear is: "Do I need to pay both Plastic Packaging Tax and EPR fees?" The answer, for most businesses dealing with plastic packaging, is yes. PPT and EPR are entirely separate systems with different purposes, different administrators, different thresholds, and different calculations. Here is a direct comparison.
| Attribute | Plastic Packaging Tax (PPT) | Extended Producer Responsibility (EPR) |
|---|---|---|
| Administrator | HMRC | DEFRA |
| Type | Tax (paid to government) | Fee (paid to scheme administrator) |
| Scope | Plastic packaging only | All packaging materials (plastic, paper, glass, metal, wood) |
| What it targets | Recycled content — does the packaging contain 30%+ recycled plastic? | Recyclability — can the packaging be recycled through UK infrastructure? |
| Registration threshold | 10 tonnes of plastic packaging in any 12-month period | Turnover £1M+ and 25+ tonnes of all packaging (small), or turnover £2M+ and 50+ tonnes (large) |
| Rate | £228.82 per tonne (flat rate, from April 2026) | Variable by material, format, and RAM rating (typically £50–£500+/tonne) |
| Exemption mechanism | 30%+ recycled content = exempt from tax | Green RAM rating = lower fees (but never zero) |
| Reporting frequency | Quarterly returns to HMRC | Twice per year (large) or annually (small) to DEFRA — see EPR deadline calendar |
| Records retention | 6 years | As specified by scheme administrator |
| Enforcement | HMRC (tax penalties, interest, prosecution) | Environment Agency (civil penalties up to £100,000) |
The critical point is that these two systems address different problems. PPT asks: is your plastic packaging made from recycled material? EPR asks: can your packaging be recycled after the consumer is finished with it? Businesses with EPR obligations must also understand Packaging Recovery Notes (PRNs and PERNs), which evidence that packaging waste has been recovered and recycled. A PET bottle made from 100% virgin plastic pays PPT but may score Green on RAM because PET is widely recyclable. Conversely, a pouch made from 50% recycled multi-layer plastic is exempt from PPT but will likely score Red on RAM because multi-layer flexibles cannot be recycled at scale.
Optimise for both, not one
The smartest packaging strategy addresses both obligations simultaneously. Increasing recycled content reduces or eliminates your PPT bill. Improving recyclability reduces your EPR fees. The ideal outcome is packaging that contains 30%+ recycled content (PPT exempt) and is mono-material and widely recyclable (Green RAM rating, lowest EPR fees).

Start Your Free Trial →How to Calculate Your PPT Liability
Calculating your Plastic Packaging Tax liability is more straightforward than EPR fee calculation, but it requires accurate data about your packaging volumes and recycled content. The formula is simple:
Non-exempt tonnage is the total weight of plastic packaging components that contain less than 30% recycled plastic content.
The key to an accurate calculation is correctly identifying which of your plastic packaging is exempt (30%+ recycled content) and which is not. You must also include all plastic packaging you manufacture or import, including packaging that arrives already filled with product.
Worked example
A food manufacturer uses 50 tonnes of plastic packaging per year. Of this, 20 tonnes consists of rPET trays containing 35% recycled content (exempt). The remaining 30 tonnes consists of LDPE film wrapping with no recycled content (taxable).
A drinks importer brings 200 tonnes of PET bottles filled with water into the UK per year. The bottles contain 0% recycled content. All 200 tonnes are taxable.
In the second example, if the importer could switch to bottles containing 30% rPET, the entire £45,764 liability would be eliminated. This illustrates the binary nature of PPT — the incentive to reach the 30% threshold is absolute because the saving is the full tax amount, not a partial reduction.
Registration and Reporting
Once you determine that you need to register — or are likely to need to register — for the Plastic Packaging Tax, the process runs through HMRC's online systems. Here is what you need to know about the practical mechanics.
When to register
You must register within 30 days of the date you first exceed the 10-tonne threshold. Alternatively, if you have not yet reached 10 tonnes but reasonably expect to do so within the next 30 days, you must register immediately. This forward-looking requirement means you cannot wait until you have actually crossed the line — you need to register as soon as you can see it coming.
How to register
Registration is done through the HMRC online portal. You will need your Government Gateway credentials (the same login used for VAT, PAYE, and other HMRC taxes). The registration form requires information about your business, the types of plastic packaging you manufacture or import, and your estimated annual tonnage.
Quarterly returns
Once registered, you must file a PPT return every quarter. Each return covers a standard quarter aligned with the tax year:
- Q1: April to June — return due by the last working day of July
- Q2: July to September — return due by the last working day of October
- Q3: October to December — return due by the last working day of January
- Q4: January to March — return due by the last working day of April
Each return must report the total weight of plastic packaging components you manufactured or imported during the quarter, broken down into exempt (30%+ recycled content) and non-exempt categories. The tax due is calculated on the non-exempt tonnage and must be paid by the return deadline. If you also have EPR obligations, keep our EPR deadline calendar to hand so you do not confuse the two submission timetables.
Record keeping
HMRC requires you to keep comprehensive records for at least 6 years. These records must be sufficient to verify your quarterly returns and should include:
- Weights of all plastic packaging manufactured or imported, by component
- Recycled content percentages for each packaging line
- Supplier evidence supporting recycled content claims
- Details of any exported packaging (which may qualify for credit or relief)
- Invoices, delivery notes, and customs declarations for imported packaging
Export credit
If you manufacture plastic packaging in the UK and export it (either empty or filled), you may be able to claim a credit against your PPT liability. The credit applies because PPT is intended to tax packaging placed on the UK market, not packaging exported for use overseas. Exported packaging should be tracked separately and claimed on your quarterly return. Detailed export records are essential for supporting these claims.
Strategies to Reduce Your PPT Bill
The most effective way to reduce your Plastic Packaging Tax liability is straightforward: increase the recycled content in your plastic packaging to 30% or above. But there are several practical approaches to achieving this, along with other strategies that can reduce your overall exposure.
Reformulate packaging with 30%+ recycled content
The single most impactful action. Work with your packaging suppliers to incorporate recycled resin (rPET, rHDPE, rPP) at 30% or above by weight. Many resin suppliers now offer recycled content blends that maintain the performance characteristics required for food contact, cosmetics, and other applications. The price premium for recycled resin has narrowed significantly since 2022 and is typically far less than the £228.82/tonne tax saving.
Switch to non-plastic alternatives where feasible
If a packaging component cannot practicably incorporate 30% recycled plastic, consider whether it could be replaced with a non-plastic alternative entirely. Paper-based trays, aluminium containers, glass bottles, and fibre-based pouches are all outside PPT scope. This approach may also improve your EPR position if the alternative achieves a better RAM rating. Note that the Deposit Return Scheme launching in 2027 will further reshape the economics of plastic beverage containers, so factor DRS into any material-switch decisions.
Reduce the weight of plastic packaging
PPT is charged per tonne. Lightweighting your plastic packaging directly reduces the taxable weight, even if the recycled content remains below 30%. A 15% weight reduction across your plastic packaging portfolio means a 15% reduction in PPT, independent of any recycled content improvements. Combine lightweighting with recycled content increases for maximum impact.
Consolidate packaging lines to reach 30% threshold
If you have multiple packaging lines using similar plastic formats, consider consolidating them onto a single specification that incorporates 30%+ recycled content. The cost of reformulation may be more justifiable when spread across higher volumes, and you eliminate the administrative burden of tracking and reporting mixed exempt/non-exempt lines.
Negotiate recycled content into supplier contracts
For importers who purchase filled packaging from overseas suppliers, PPT liability falls on the importer, not the manufacturer. This means you are paying the tax for your supplier's material choice. Build recycled content requirements into your procurement specifications and contracts. Many overseas manufacturers can supply 30%+ recycled content packaging at minimal premium — they simply need the contractual requirement to justify the switch.
Explore chemical recycling supply chains
For packaging applications where mechanical recycled content is difficult to achieve (due to food safety, clarity, or performance requirements), chemical recycling may offer a route to 30%. Chemically recycled plastic can be functionally identical to virgin material while counting towards the recycled content threshold. Mass balance allocation allows you to claim recycled content based on certified input volumes even in blended production runs.
The breakeven calculation is simple
If the cost of switching to 30%+ recycled content resin adds less than £228.82 per tonne to your material costs, the switch pays for itself immediately through PPT savings alone. In practice, the recycled content premium for most common polymers (PET, HDPE, PP) is currently in the range of £50–£150 per tonne — well below the tax rate. For many producers, reformulation is already the cheaper option even before considering the reputational and EPR benefits.
Common PPT Mistakes
After several years of the Plastic Packaging Tax being in effect, HMRC compliance activity has identified recurring errors that businesses make. Avoiding these common mistakes can save you from penalties, interest, and the disruption of a compliance investigation.
Not counting imported filled packaging
Many importers fail to account for the packaging that arrives with imported goods. If you import bottled drinks, canned foods in plastic trays, or any product in plastic packaging, the weight of that packaging is within scope of PPT. The tax falls on the importer, not the overseas manufacturer. This is one of the most common sources of under-reporting discovered during HMRC checks.
Ignoring transit and secondary packaging
PPT applies to all plastic packaging, not just primary (consumer-facing) packaging. Plastic stretch wrap used on pallets, plastic strapping, plastic pallet caps, and plastic crates are all in scope if manufactured in or imported to the UK. Businesses that focus only on their product packaging and ignore their logistics packaging often understate their PPT liability significantly.
Assuming bio-based or compostable plastics are exempt
As noted earlier, all plastics are within PPT scope regardless of feedstock origin. PLA, bio-PE, bio-PET, and compostable packaging films all count as plastic. The only route to exemption is 30% recycled content. Businesses that have switched to "bio" or "compostable" packaging expecting PPT savings have found themselves with the same tax bill and often higher material costs.
Not holding adequate recycled content evidence
Claiming the 30% exemption without holding proper documentary evidence is a serious compliance risk. HMRC can disallow exemption claims where evidence is inadequate, resulting in back-dated tax liability plus interest and penalties. Verbal assurances from suppliers are not sufficient. You need written certificates, test reports, or declarations that can withstand audit scrutiny.
Failing to monitor the 10-tonne threshold
The rolling 12-month threshold means your obligation can be triggered at any point during the year, not just at year-end. Businesses with seasonal fluctuations or growing import volumes sometimes cross the threshold mid-year without realising it. By the time they register, they are already late and facing penalties. If you are anywhere near 10 tonnes, implement monthly tracking of your plastic packaging volumes.
Confusing PPT with EPR reporting
PPT and EPR have different definitions, different scopes, and different reporting formats. Data prepared for your DEFRA EPR submission cannot simply be copied into your HMRC PPT return. The tonnage figures may differ (EPR covers all materials; PPT covers only plastic), the categorisation differs, and the administrator differs. Treat them as entirely separate compliance workstreams with their own data collection processes. When your EPR fees arrive, our PackUK invoice guide explains how to read and verify the charges.
