Two importers bring in the same product, under the same commodity code, in the same month. One pays the full rate of duty, the other pays a reduced rate. The difference is not a secret discount: it is a tariff rate quota, and the second importer simply claimed it on the declaration. This guide explains how tariff rate quotas in the UK work, how to claim one, and what can go wrong.
What is a tariff rate quota?
HMRC describes tariff quotas as a way to import limited amounts of specific goods, sometimes only from specific countries, at a rate of duty lower than would otherwise apply. Once the quota volume for a period has been used up, the normal rate applies again until the quota reopens.
Three features matter in practice:
- Limited volume – each quota covers a fixed quantity for a set period.
- Specific goods – the quota is linked to particular commodity codes, so correct classification comes first.
- Sometimes a specific origin – some quotas are open only to goods from named countries, which means you must be able to show where the goods come from.
Every quota has a 6-digit order number. That number is what you put on the customs declaration to make the claim.
First come first served vs licensed quotas
According to HMRC guidance, most tariff quotas in the UK operate on a first come first served basis. You do not apply in advance; you claim the quota on the import declaration when the goods are released into free circulation. Because allocations follow the order of claims, submitting early gives you a better chance of success.
Other quotas are licence based: access depends on getting an import licence before the goods are imported. HMRC notes that quotas whose order numbers begin with 054 are administered by the Rural Payments Agency (RPA). These typically concern agricultural products, and without the licence the quota rate is simply not available.
A third, less common category covers quotas tied to authorised use, where prior written authorisation from HMRC is needed and its reference must appear on the declaration.
How to claim a tariff rate quota on your declaration
The claim is made on the import declaration in the Customs Declaration Service (CDS) – either by you or by the customs agent handling the entry. According to gov.uk:
- Classify the goods and confirm the commodity code in the UK Trade Tariff.
- Check whether that code is covered by a quota and note the 6-digit order number (the Trade Tariff has a quota search).
- Enter the order number in Data Element 8/1 of the declaration.
- Declare the supporting documents (for example proof of origin or a licence) in Data Element 2/3.
- Keep the evidence on file – HMRC can ask for it after clearance.
If you work with a customs agent, send them the order number and supporting documents together with the invoice. A missing order number means the full rate is charged, even when the quota was open. The Easy Clearance UK import duty and VAT calculator helps you estimate the full-rate scenario, so you can see how much the quota is worth before the goods ship.
Open, critical and exhausted: reading the quota status
The Trade Tariff shows a status for each quota, and gov.uk explains what each means for your claim:
- Open – valid claims receive the reduced rate.
- Critical – the balance is running low and there is no guarantee your claim will succeed. You must provide security equal to the full rate of duty before the claim is registered.
- Exhausted – the volume is used up and the full rate of duty applies.
Balances are updated in the Trade Tariff after each allocation, so the figure you see is not a live counter. Treat a low balance as a signal to budget for the full rate.
Late claims: the 3-year window
If the quota was not claimed at import, all is not necessarily lost. HMRC guidance states that you may be able to make a claim up to 3 years after the goods were imported, if the tariff quota is still available. In practice that last condition matters: for popular quotas the volume may be gone long before you notice the missed claim. The better habit is to check quota eligibility during classification, not after the duty bill arrives.
Quotas, origin and other duties
Quotas limited to specific countries sit alongside the UK’s trade agreements. For goods moving between the EU and GB, the Trade and Cooperation Agreement already offers zero duty for originating goods, so a quota is usually relevant for non-originating goods or goods from other partners. Our overview of the UK–EU Trade and Cooperation Agreement explains the origin side. Easy Clearance also covers zero-tariff rules of origin under the TCA in more detail.
A quota reduces customs duty only. It does not remove import VAT, excise or any trade remedy measure that applies to the goods. For a step-by-step view of how the reduced rate interacts with the rest of the entry, see the Easy Clearance guide to using UK tariff rate quotas in practice.
Checklist before you import quota goods

- ☐ Quota order number identified (6 digits)
- ☐ Quota type checked: first come first served, licence (054 – RPA) or authorised use
- ☐ Licence or HMRC authorisation in hand, if required
- ☐ Origin evidence ready, if the quota is country-specific
- ☐ Quota status checked: open, critical or exhausted
- ☐ Security budgeted if the status is critical
- ☐ Order number and documents passed to your customs agent
Mini-FAQ
Do I need to apply in advance for a first come first served quota?
No. You claim it on the import declaration by entering the order number in Data Element 8/1 when the goods enter free circulation.
What happens if the quota is critical when my goods arrive?
You must provide security equal to the full rate of duty before HMRC registers the claim, because there is no guarantee the claim will be allowed.
Can I claim a quota after the goods have been imported?
Possibly. gov.uk says a claim can be made up to 3 years after import, but only if the quota is still available.
Who handles licensed quotas?
Quotas with order numbers starting 054 are administered by the Rural Payments Agency, and you need the licence before importing.
Unsure whether your goods qualify? Easy Clearance, a customs agency registered in CDS with a UK EORI number, can check the classification and quota before your shipment leaves.
