description: Produces one dated packaging file for a UK hospitality business - whether the packaging rules oblige you personally or only reach you through your suppliers' prices, which of your packaging lines are banned outright, what the published per tonne fees are for the materials you actually buy, where the plastic packaging tax threshold sits, and the questions to put to each supplier in writing. Use before you renew a packaging supply contract, when a supplier raises prices and blames the regulations, or when you have been told you need to register and do not know whether that is true.

# Find out what your packaging actually costs you now, and whether the rules are yours or your supplier's

You give this your packaging lines, what you get through in a year, your turnover band and your supplier invoices. You get back one dated file: whether the extended producer responsibility duties fall on you or reach you only as a price rise, your packaging priced at the published rates by material, the lines that are banned outright with the wording that bans them, where the plastic packaging tax threshold sits relative to you, and a numbered list of what you cannot answer without your suppliers. It does not tell you that you are or are not obligated. That is a determination for the regulator and your accountant, and this file is built so both can see the working.

## What it does

1. **Answer the obligation question first with the two thresholds, because most independent venues fail one of them and everything downstream changes.** GOV.UK sets three conditions that must all be met, and lists them as three bullets: "established in the UK", "supplied or imported more than 25 tonnes of packaging in the UK in the previous year", and "annual turnover worldwide was £1 million or more". Twenty five tonnes is a great deal of packaging for a single site, so a venue over the turnover line very often sits under the tonnage line. Write both numbers into the file with the working, because "we think we're too small" is not a record and a supplier or a landlord will eventually ask for one. Charities have a separate answer: "Charities that supply or import filled or unfilled packaging in the UK are exempt from EPR for packaging requirements."

2. **Work out which packaging activities you actually perform, because the activity decides whose tonnage it is.** The scheme allocates packaging to whoever does the named thing to it, and a hospitality business usually does more than one. You are selling filled packaging to an end user when you hand over a takeaway box. You may be the brand owner if your name is printed on the cup. You may be an importer if you buy direct from outside the UK. You are none of these for a case of wine you serve by the glass, because that packaging was placed on the market by somebody else. GOV.UK's phrasing for the seller activity is "selling filled packaging to an end user (consumer or business)". List each line against the activity and the holder of the obligation. This is the step that turns "we use a lot of packaging" into a tonnage that is legally yours and a larger tonnage that is not.

3. **If both thresholds are met, settle small against large, because the duties differ by more than the label suggests.** The table is exact, and the top right cell surprises people: under 25 tonnes is no obligation at any turnover; 25 to 50 tonnes is a small producer at any turnover above £1 million; and over 50 tonnes is a small producer between £1 million and £2 million turnover but a large producer above £2 million. A small producer must register with the environmental regulator, "report packaging data every year", and keep the data for seven years. A large producer must do all of that, "report packaging data every 6 months", obtain recycling notes, submit compliance certificates annually, and "pay a waste disposal fee for any household packaging to PackUK each year". The fee is the large producer's cost. A small producer reports and does not pay it.

4. **Price your packaging at the published rates whichever side of the line you are on, because that is the number moving inside your supplier invoices.** The confirmed base fees for 2025 to 2026, in pounds per tonne, are: aluminium £266, fibre-based composite £461, glass £192, paper and card £196, plastic £423, steel £259, wood £280, and other £259. Those fees "will cover PackUK costs and provide local authorities with additional income to cover the cost of recycling and disposal of waste packaging materials". Multiply your annual tonnage per material by that rate and you have the sum sitting inside your supply chain whether or not it appears on your bill. Fibre-based composite is worth looking at twice: at £461 a tonne it is the dearest material in the table, and a coffee counter usually holds more of it than anyone realised.

5. **Sort the same lines by recyclability rating, because from the 2026 to 2027 financial year the rating multiplies the fee.** Under the Recyclability Assessment Methodology each item is rated, with "red being the least recyclable and green being the most recyclable". PackUK's modulation statement is careful about what this does and does not do: "The modulation of household packaging waste disposal fees will not increase the total of all household packaging waste disposal fees paid. Instead, it will affect how these costs are allocated by material." The red multiplier escalates over three years, 1.2 in 2026 to 2027, 1.6 in 2027 to 2028 and 2.0 in 2028 to 2029. The illustrative Year 2 figures show the spread inside one material: plastic at £415 green, £455 amber and £545 red per tonne. Those are illustrative and must be labelled as such, because the page says "The fees are subject to change as more information becomes available" and that "Confirmed fees for Year 2 are expected to be published in June 2026". Check whether the confirmed figures have since appeared before you quote any of them.

6. **Check the plastic packaging tax separately, because it is a different tax with a different threshold and people conflate the two.** You need to register if you "expect to import into the UK or manufacture in the UK 10 tonnes or more of finished plastic packaging components in the next 30 days" or "have imported into the UK or manufactured in the UK 10 tonnes or more of finished plastic packaging components in the last 12 months". The tax bites on components that "contain less than 30% recycled plastic", and the rate is "£228.82 per tonne from 1 April 2026". A restaurant buying boxes from a UK supplier is neither importing nor manufacturing them, so the tax is the supplier's to register for and yours to see in the price. A venue importing its own branded packaging from overseas is in a different position and should put that volume in front of its accountant.

7. **Check the single-use plastics ban, which applies to you at any size and has no turnover test at all.** In England four things are banned with no exemptions: "drinks stirrers", "balloon sticks", "cutlery", and "food and drink containers made of expanded and extruded polystyrene". Plates, bowls and trays are banned for supply to the public but permitted where "the items are packaging, pre-filled or filled at the point of sale", and the published example is exactly a hospitality one: "a plate filled at the counter of an establishment selling ready-to-consume food, such as a takeaway, bakery, canteen or public house". So the same plastic plate is lawful filled at your counter and unlawful handed over empty. Enforcement is local and physical: "Local authorities will carry out inspections to make sure the rules are being followed", including test purchases, and "If you break the law, you could be fined and ordered to cover the cost of the investigation."

8. **Ask your suppliers the three questions in writing, because your own data is worthless without theirs.** For each packaging line: what does one unit weigh, what material is it under the scheme's own categories, and what recyclability rating does it carry. Without unit weights you cannot convert cases into tonnes and every figure in steps 4 and 5 is a guess. Without the material category you will price a fibre-based composite cup as paper and card and understate it by £265 a tonne at the Year 1 rates. Record who you asked, when, and what came back. A supplier who cannot answer the weight question is telling you something about whether their own reporting is real.

9. **Build the register, date it, and diary the dates that will change it.** One row per packaging line: description, supplier, material category, unit weight, annual units, annual tonnage, the fee rate applied and its source, the recyclability rating if known, and whether the line is banned, exempt or unaffected. Date the file and record when each source was read. Three dates go in the diary: the confirmed Year 2 fees, the 1.6 red multiplier from the 2027 to 2028 year, and your own next reporting deadline if you turn out to be obligated. Fee schedules here are reissued every year, and a packaging register with no date on it will be quoted with confidence eighteen months after it stopped being true.

## Then it checks

1. The file states the annual packaging tonnage and the worldwide turnover as separate numbers with the working behind each, and reaches the obligation question through both rather than through one.
2. Every packaging line is assigned to a named activity with the holder of the obligation identified, and no line is left without one.
3. Every fee rate in the file is labelled either confirmed or illustrative, carries the year it applies to, and names the page it was read from with the date of reading.
4. No illustrative Year 2 figure is presented as a confirmed fee, and the file records whether confirmed Year 2 fees had been published at the time it was built.
5. The plastic packaging tax section states whether the business imports or manufactures finished plastic packaging components at all, and does not apply the 10 tonne threshold to packaging merely bought from a UK supplier.
6. Every banned item on the premises is listed with the wording that bans it and the exemption tested against it, and the file states nowhere that the business is compliant, obligated or exempt as a matter of law.

Any check fails: name it, redo that step once. Failed twice: say what is wrong and stop.

## Rules
- Public information only.
- Never invent a fact, a number or a quote.
- Anything sent in someone's name says whose name it is. A letter asking a supplier for unit weights goes out over the name of the person who will have to read the reply.
- Never tell an owner they are an obligated producer, that they are exempt, or that they need to register. Those are determinations for the environmental regulator and the owner's accountant, and an owner told "you are fine" stops asking the people who could actually tell them.
- Refuse to present an illustrative fee as a confirmed one, and refuse to carry any fee figure forward into a later file without re-reading the page it came from. Every rate in this area has been reissued at least once.
- Never estimate a unit weight in order to complete a tonnage. A missing weight is a gap with a supplier's name against it, not a number with a shrug behind it.
- Never state a benchmark for how much packaging a venue of a given size uses, a typical annual fee, or a percentage saving from changing material. No published figure exists for a single independent UK venue, and an owner who budgets from a borrowed number will conclude their own site is failing.
- Never treat a supplier's statement that fees are "included" or "already covered" as established. Record who said it and on what date, and leave it as an open question until an invoice line or a written confirmation arrives.
- This output is a working document prepared for the owner to check with their accountant, their packaging suppliers and their environmental regulator or local authority trading standards team before it is relied on. It gathers published thresholds and fee rates, records what the site buys and names the gaps. It is not tax advice and it does not certify compliance with anything.

# packaging-check

## You are given
One UK hospitality business's packaging position, already judged by Claude. Specifically: the business name, its legal form and whether it is a charity; its worldwide annual turnover for the stated year with the source of that figure; a line by line list of every packaging item it buys or supplies, each carrying a description, the supplier, the pack or case size, the units bought in the stated year, the unit weight in grams where a supplier has given one, the material category, and the recyclability rating where one has been supplied; Claude's judgement for each line of which packaging activity applies and who holds the obligation; Claude's judgement of whether the business imports or manufactures finished plastic packaging components at all; the published fee rates Claude is applying, each labelled confirmed or illustrative with its year and source URL; the recyclability modulation factors and their years; the list of banned single-use plastic items and the exemption wording; and every supplier question asked with the date asked and the answer received. Where a judgement or a figure is missing it arrives as the words `not supplied`.

## Produce

6. `supplier-questions.csv` with columns: `supplier`, `line_refs`, `question`, `date_asked`, `asked_by`, `date_answered`, `answer_verbatim`, `status`. `question` is exactly one of `unit weight in grams`, `material category under the scheme`, `recyclability rating`. `status` is exactly one of `answered`, `asked and not answered`, `not yet asked`.
7. `gaps.md` - a numbered list of: every line with no supplied unit weight and the supplier it belongs to; every line with `not supplied` in any judgement column; every fee rate used that is `illustrative`, naming the date confirmed figures are expected; every banned item with outcome `needs a decision by the owner`; every supplier question with status `asked and not answered` and how many days have passed; any missing source URL or read date; and the three diary dates.

## Rules
- Codex measures, converts, prices and records. It never invents, never assigns a packaging activity that was not supplied, never rewords a supplier's description or a published fee, and never makes the obligated producer judgement that was supplied to it.
- Never estimate, infer or substitute a unit weight. A line with no supplied weight has an empty `annual_tonnes` and an empty `exposure_gbp`, and appears in `gaps.md`. Filling the gap with an assumption is the one thing that would make every figure in `fee-exposure.csv` wrong at once.
- Never write `confirmed` into `fee_status` for a rate the input labelled illustrative, and never write an illustrative figure into any summary sentence without the word illustrative beside it.
- Never state that the business is an obligated producer, is exempt, must register, or complies with anything. None of these goes into any file.
- Never apply the plastic packaging tax threshold to packaging the business merely buys from a UK supplier. Where both `imports_finished_components` and `manufactures_finished_components` are `no`, the tonnage columns are left empty and `registration_question_open` is `no`.
- Never write a benchmark, an industry average, a typical annual packaging spend or tonnage, or a percentage saving from switching material. No such figure exists for a single independent UK venue and none is to appear in any file.
- Never record a threshold, a rate or a ban without its source URL and the date that source was read, both copied from the input.
- A rule or a rate that has not yet commenced is recorded with its start date and is never applied to a current year figure.
- Use British English, GBP for money and DD Month YYYY for every date. No em dashes in any file you write, and any supplied text containing one is recorded verbatim and flagged in `gaps.md`.
- Every file ends with this line: this is a working document prepared for the owner to check with their accountant, their packaging suppliers and their regulator before it is relied on; it is not tax advice and it does not certify compliance.

## Return
The absolute path of each file written, the row count of each CSV, the worldwide turnover and annual packaging tonnage as recorded with the tonnage method, the producer class as supplied, the number of lines with a supplied unit weight against those without with the suppliers named, the total fee exposure by material split into confirmed and illustrative subtotals, the single largest material by exposure, the count of lines by recyclability rating including `not supplied`, whether the plastic packaging tax registration question is open and why, every banned item found with its outcome, the number of supplier questions answered against those outstanding with the oldest date asked, and the `gaps.md` item count.

Built from the best public work on this

Sources for packaging-check

Everything below was opened and read on 16 September 2026. Nothing is cited that could not be loaded.

1. GOV.UK, "Extended producer responsibility for packaging: who is affected and what to do"

https://www.gov.uk/guidance/extended-producer-responsibility-for-packaging-who-is-affected-and-what-to-do, published 7 June 2022, last updated 19 August 2026, read 16 September 2026.

The gateway page, and the only one that answers the question an owner actually has, which is whether any of this is theirs. Three conditions have to be met together, and the page puts them as three bullets: "established in the UK", "supplied or imported more than 25 tonnes of packaging in the UK in the previous year", and "annual turnover worldwide was £1 million or more". Step 1 keeps them as two separate numbers rather than one verdict, because they fail independently and an owner who only ever hears "you're too small" has no idea which of the two is doing the work, or how close they are to crossing it.

The classification table is quoted in step 3 because its shape is not the shape people expect. Reading across, "Less than 25 tonnes" is "No obligation" at every turnover band including above £2 million. "From 25 tonnes to 50 tonnes" is "Small producer" both between £1 million and £2 million and above £2 million. Only "More than 50 tonnes" combined with "More than £2 million" produces a large producer. So a high turnover business with modest packaging volumes is a small producer, and the cost consequence is large: a large producer must "pay a waste disposal fee for any household packaging to PackUK each year" while a small producer's duty is to register, "report packaging data every year" and keep the data for seven years.

The activity language in step 2 comes from the same page, including "selling filled packaging to an end user (consumer or business)", which is the activity a takeaway performs every time it fills a box at the counter. The charity position is stated flatly and is worth knowing in a sector full of social enterprises: "Charities that supply or import filled or unfilled packaging in the UK are exempt from EPR for packaging requirements."

Where the skill departs: the page carries a good deal on nation data reporting, recycling notes, compliance schemes and the mechanics of registering with the environmental regulator. None of that is written into the skill, because it only applies once the thresholds have been crossed, and a venue that has crossed them has an accountant and probably a compliance scheme already. The skill stops at the determination and hands over. It also does not state deadlines for submitting data, because the page gives the frequency without giving the dates and inventing them would be the exact failure the skill is built to avoid.

2. GOV.UK and PackUK, "Extended Producer Responsibility for Packaging: 2025 base fees"

https://www.gov.uk/government/publications/extended-producer-responsibility-for-packaging-2025-base-fees/extended-producer-responsibility-for-packaging-2025-base-fees, updated 30 June 2025, read 16 September 2026.

The only confirmed per tonne figures in the set, and therefore the only ones the skill lets anybody multiply without a caveat: aluminium £266, fibre-based composite £461, glass £192, paper and card £196, plastic £423, steel £259, wood £280 and other £259. The page also says what the money is for: "The fees paid by producers will cover PackUK costs and provide local authorities with additional income to cover the cost of recycling and disposal of waste packaging materials."

Step 4 makes a venue price its own packaging at these rates even when it is not obligated to pay them, and that is the most useful thing in the skill. The fees sit inside the price of every box, cup and case the venue buys, invisibly, and a supplier attributing a price rise to "the new regulations" can then be tested against a number rather than believed. The gap between fibre-based composite at £461 and paper and card at £196 is the one that most often surprises a coffee counter, because the cup and the sleeve look like the same material and are not.

Where the skill departs: the base fees document sits behind a larger methodology about how local authority payments are calculated and how household packaging is distinguished from non-household. The skill does not teach that distinction, because it is a determination that affects what an obligated producer pays rather than what a non-obligated venue is charged in its supply prices, and getting it wrong in a self-built file would produce a confident number with no basis.

3. GOV.UK and PackUK, "Year 2 illustrative waste disposal fees"

https://www.gov.uk/government/publications/year-2-illustrative-waste-disposal-fees-extended-producer-responsibility-for-packaging/year-2-illustrative-waste-disposal-fees-extended-producer-responsibility-for-packaging, updated 19 December 2025, read 16 September 2026.

Cited for two reasons, and the second matters more than the first. The first is the figures themselves, which show the spread that recyclability now creates inside a single material: plastic at £415 green, £455 amber and £545 red per tonne, fibre-based composite at £475, £525 and £630, glass at £185, £205 and £245.

The second is the health warning, which the skill quotes rather than paraphrases because it governs how every one of those numbers may be used: "The fees are subject to change as more information becomes available" and "These fees are intended to help with planning but are likely to change significantly as producers submit more data and compliance is monitored by regulators." The page states that "Confirmed fees for Year 2 are expected to be published in June 2026, following the reporting deadline of 1 April 2026 for packaging supplied by registered producers in 2025." That expectation is now in the past, so the skill instructs the user to check whether confirmed figures have appeared before quoting any illustrative one, and the CODEX file carries a hard `fee_status` column so that an illustrative figure cannot quietly become a confirmed one when the spreadsheet is copied.

Where the skill departs: the page invites planning against these numbers. The skill allows the arithmetic and refuses the framing, because a venue budgeting against a figure the publisher itself expects to "change significantly" will treat the variance as a failure of its own forecasting. Every derived total in the output is split into confirmed and illustrative subtotals for exactly that reason.

4. GOV.UK and PackUK, "Producer disposal fees modulation statement"

https://www.gov.uk/government/publications/extended-producer-responsibility-for-packaging-modulated-disposal-fees/packuk-extended-producer-responsibility-epr-for-packaging-producer-disposal-fees-modulation-statement, published 28 June 2025, last updated 17 February 2026, read 16 September 2026.

This is the document that turns packaging choice into a price signal. Under the Recyclability Assessment Methodology every item is rated, with "red being the least recyclable and green being the most recyclable", and the red multiplier escalates over three consecutive years, 1.2 in 2026 to 2027, 1.6 in 2027 to 2028 and 2.0 in 2028 to 2029.

The sentence the skill leans on hardest is the one that sets expectations correctly: "The modulation of household packaging waste disposal fees will not increase the total of all household packaging waste disposal fees paid. Instead, it will affect how these costs are allocated by material." That is the difference between a tax rise and a redistribution, and it is why step 5 sorts lines by rating rather than treating modulation as a general inflation. A venue that moves a red line to amber is moving its own cost, not reducing a national total, and that is a perfectly good reason to do it.

Where the skill departs: the statement includes specific treatment for medical packaging, where red-rated items are modulated only where it is not possible to use more recyclable packaging because of legal rules. That has no application in hospitality and is left out rather than carried along as decoration. The skill also does not attempt to rate any packaging item itself. The rating is an assessment made under a published methodology, and a guess dressed as a rating would corrupt the whole fee calculation, so the rating arrives from the supplier or the column reads `not supplied`.

5. HMRC and GOV.UK, "Check if you need to register for Plastic Packaging Tax"

https://www.gov.uk/guidance/check-if-you-need-to-register-for-plastic-packaging-tax, published 4 November 2021, last updated 12 February 2026, read 16 September 2026.

A separate tax with a separate threshold, quoted in step 6 so that the two regimes stop being confused with each other. Registration is triggered where you "expect to import into the UK or manufacture in the UK 10 tonnes or more of finished plastic packaging components in the next 30 days" or "have imported into the UK or manufactured in the UK 10 tonnes or more of finished plastic packaging components in the last 12 months". The tax applies to components that "contain less than 30% recycled plastic", at "£228.82 per tonne from 1 April 2026".

The load-bearing words are "import" and "manufacture". A restaurant buying takeaway boxes from a UK wholesaler does neither, so the tax is the wholesaler's registration and the venue's price. A venue ordering its own branded packaging direct from a factory abroad is importing, and that is the case the skill flags for the accountant rather than deciding.

Where the skill departs: the guidance runs on into registration mechanics, accounting periods, deferral, credits and the tax's interaction with exported goods. The skill takes the threshold test and the rate and stops. It also refuses to apply the 10 tonne threshold to packaging bought domestically, which is the single most common misreading of this page, and enforces that refusal in the CODEX rules rather than trusting it to be remembered.

6. GOV.UK, "Single-use plastics ban: plates, bowls, trays, containers, cutlery and balloon sticks"

https://www.gov.uk/guidance/single-use-plastics-ban-plates-bowls-trays-containers-cutlery-and-balloon-sticks, published 22 January 2024, last updated 7 October 2024, read 16 September 2026.

The only source in the set with no size threshold at all, which is why step 7 exists and why it is written for every venue rather than only for the obligated ones. Four categories have no exemptions: "drinks stirrers", "balloon sticks", "cutlery", and "food and drink containers made of expanded and extruded polystyrene".

Plates, bowls and trays have an exemption that reads oddly until you see the example. They may still be supplied where "the items are packaging, pre-filled or filled at the point of sale", and the page's illustration is "a plate filled at the counter of an establishment selling ready-to-consume food, such as a takeaway, bakery, canteen or public house". So the lawfulness of the identical item depends on whether it leaves your counter with food on it. A stack of empty plastic plates handed to a customer at a self-service buffet and the same plate plated up behind the counter are two different legal positions, and that is the distinction the skill forces into `banned-items.csv` rather than leaving it to judgement on the day.

Enforcement is local and physical rather than paper based: "Local authorities will carry out inspections to make sure the rules are being followed", inspectors "may visit your premises, make test purchases, speak to staff and request records", and "If you break the law, you could be fined and ordered to cover the cost of the investigation." The costs clause is the part owners have not usually heard.

Where the skill departs: this page is England only. Scotland, Wales and Northern Ireland have their own bans with their own scope and dates, which the skill does not describe because it has not read them, and it says so rather than implying the English list travels. A venue outside England should treat step 7 as unverified for its nation.

Best public prompt we found for this job

There is no public prompt or skill for UK packaging producer responsibility. The closest public artefact for the shape of the job, which is a threshold determination feeding a costed file that somebody else signs off, is the `tax-prep` skill in Anthropic's `knowledge-work-plugins` repository, raw source at https://raw.githubusercontent.com/anthropics/knowledge-work-plugins/main/small-business/skills/tax-prep/SKILL.md. The repository has 24,124 stars, read from api.github.com on 16 September 2026. Its best instinct is the gate:

Do not calculate anything until the books in scope are settled. If items are still open, say what they are and what they do to the tax number

That is exactly the failure mode here. A packaging fee exposure calculated with half the unit weights missing looks like a number and is not one, so this skill will not fill a missing weight with an assumption, leaves `annual_tonnes` empty, and puts the supplier's name in `gaps.md`. The same skill opens every deliverable with a framing line, "Prepared for review by your accountant", followed by a flat statement that it is not tax advice. That is the ancestor of the closing line on every file here.

What we did not copy. Its tax arithmetic is US federal and its output is an estimated payment, which is a number the owner sends to a revenue authority. Nothing in this skill produces a figure anybody submits anywhere, and saying so plainly matters more than the calculation does. We also dropped its habit of proceeding on a stated assumption when the owner insists: it offers to calculate anyway and record the assumption, which is reasonable for an estimate that will be revised, and wrong here, because a packaging tonnage built on guessed weights would be quoted to a regulator or a supplier as though it were measured. The gap stays a gap. And we did not adopt its ledger-connector model at all, because the data this skill needs, unit weights and material categories, does not live in any accounting system and only ever arrives from a supplier who has been asked in writing.

This is a working document prepared for the owner to check with their accountant, their packaging suppliers and their regulator before it is relied on. It is not tax advice and it does not certify compliance.
