Calculators · Import duty

Import duty & VAT calculator.

Duty is charged on the goods plus freight. Import VAT is then charged on all of it, including the duty. See what actually lands as a cost — talk to Buzz about postponed VAT accounting.

Business paperwork and figures
Your duty rate depends on the commodity code and country of origin. There is no general rate — it is set by the specific commodity code and where the goods were substantially produced, and a trade agreement can take it to zero. Check the UK Integrated Online Tariff before relying on any estimate. Clearance fees, port charges and excise duty are not included here.

The basics

How import charges stack

Importing has two separate charges and they stack. Customs duty comes first, calculated on the value of the goods plus the cost of getting them here. Import VAT then applies to that total — including the duty you have just paid.

That compounding is the part that catches people budgeting from a supplier invoice. On £10,000 of goods with £800 freight and 4% duty, the VAT is charged on £11,232, not £10,000.

If you are VAT registered you can normally reclaim the import VAT on your return, so the genuine cost is the duty. Postponed VAT accounting lets you declare and reclaim it on the same return rather than paying it out and waiting for it back — which is worth setting up if you import regularly.

The commodity code is the bit you have to look up. It determines the duty rate and any licences or restrictions, and similar-sounding goods often sit under different codes. Getting it wrong is the most common and most expensive import mistake. If a shipment is large or repeating, paying a customs agent to confirm the code once is cheap by comparison.

Origin is not where it shipped from. A trade agreement can reduce duty to zero, but only if the goods meet the rules of origin — and buying Chinese-made goods through an EU distributor does not make them EU origin.

Frequently asked questions

Common questions about import duty and VAT

Is import VAT the same as the VAT on my sales?

It is the same tax at the same rate, charged at a different point. Import VAT is levied when the goods enter the UK, on the value of the goods plus freight plus any duty. If you are VAT registered and the goods are for your business, you reclaim it on your VAT return like any other input tax — so the genuine cost of importing is normally the duty, not the VAT. If you are not registered, the import VAT is a real and unrecoverable cost.

What is postponed VAT accounting and should I use it?

It lets you declare and reclaim import VAT on the same VAT return rather than paying it at the border and waiting to recover it. There is no application — you or your freight agent simply indicate it on the customs declaration, then download the monthly statement from your customs declaration service account. For anyone importing regularly it is straightforward and materially better for cash flow. The one thing that goes wrong is nobody downloading the statements, which leaves the return unsupported.

How do I find my commodity code?

The UK Integrated Online Tariff on gov.uk. It determines the duty rate, the import VAT rate, and any licences or restrictions, and similar-sounding goods routinely sit under different codes with different rates. Getting it wrong is the most common and most expensive import mistake. If a shipment is large or repeating, paying a customs agent to confirm the code once is cheap against years of the wrong rate — in either direction, because underpaying is a liability and overpaying is your own money.

What is the difference between origin and where it shipped from?

Origin is where the goods were produced or last substantially transformed. Where they shipped from is just logistics. A trade agreement can cut duty to zero, but only if the goods meet its rules of origin and you hold the right proof. Buying Chinese-manufactured goods from a warehouse in Rotterdam does not make them EU origin, and claiming preference you cannot evidence is the sort of error that surfaces years later with interest attached.

Who is responsible if the paperwork is wrong — me or my freight agent?

You are. The importer of record is legally responsible for the accuracy of the declaration even when an agent files it. Agents work from the information you give them and generally will not second-guess a commodity code or a valuation you supplied. Check what is being declared on your behalf rather than assuming the agent has verified it.

Do I pay duty on samples or replacements?

Often not, but only if declared correctly. There are reliefs for commercial samples of negligible value, returned goods, and replacements for faulty items under warranty. They all depend on the right customs procedure code at the time of import. A free-of-charge shipment declared as a normal import is fully dutiable, and "it was free" is not a defence — a value still has to be declared.

What else lands on top of duty and VAT?

Clearance and brokerage fees from your freight agent, port and handling charges, storage if the goods sit while a query is resolved, and excise duty on alcohol, tobacco and certain fuels — which is charged separately and often dwarfs customs duty. This calculator covers duty and import VAT only, so treat its figure as the floor rather than the landed cost.

Does anything change for Northern Ireland?

Yes. Northern Ireland operates under the Windsor Framework, and goods moving there can face different treatment depending on whether they are considered at risk of onward movement into the EU. Schemes exist to avoid EU duty on goods staying in Northern Ireland, but they require registration in advance. If you move goods into or through NI, this is worth establishing before the first shipment rather than during it.

A worked example

Why the VAT is bigger than you budgeted

You buy £10,000 of goods from a supplier outside the UK. Freight and insurance cost £800, and the commodity code carries 4% duty.

  • Goods£10,000
  • Freight and insurance£800
  • Customs value — duty is charged on this£10,800
  • Duty at 4%£432
  • Value for import VAT — including the duty£11,232
  • Import VAT at 20%£2,246
  • Total payable at the border£2,678

The compounding is the part that catches people budgeting from a supplier invoice. VAT is charged on £11,232, not on the £10,000 you paid for the goods — so it is £2,246 rather than £2,000.

If you are VAT registered, the £2,246 comes back on your return, and with postponed VAT accounting it never leaves in the first place. The real cost of the shipment is the £432 of duty plus your agent's clearance fee. If you are not VAT registered, the whole £2,678 is a cost — which is one of the clearer arguments for voluntary registration when you import.

What to do with the answer

Before your next shipment

  • Confirm the commodity code. It sets the duty rate and the licensing position, and similar goods sit under different codes. On a repeating import, paying once to have it verified is the cheapest thing on this list.
  • Turn on postponed VAT accounting. No application needed — it goes on the customs declaration. Then actually download the monthly statements, because that is where it falls over.
  • Budget on the landed cost, not the invoice. Duty compounds into the VAT, and clearance fees, port charges and any excise duty sit on top of both.
  • Check what your agent is declaring. You are the importer of record and the liability is yours, whoever filled in the form.
  • Evidence any preferential origin before you claim it. Shipped-from is not origin, and a preference you cannot prove becomes a debt with interest.
