UK Import Tax Calculator | Customs Duty Calculator UK

How do I calculate UK import duty and other taxes?

This UK import tax calculator, developed by the experts at ChamberCustoms and Exabler is quick, easy and free to use. It can work out the different rates of duty available to your business when importing goods. ChamberCustoms helps traders keep trading. You can use our calculator to quickly work out what needs to be paid to HMRC.

How does this customs duty calculator for the UK work?

Step 1. Firstly, we recommend that you consult the HMRC Tariff to ensure you select the correct Commodity Code for the goods you are importing. You’ll find the tariff on HMRC’s Trade Tariff HERE.

Using the example of Avocados from Mexico, you would find that the commodity code is 08044000.

Input the correct commodity code (‘classification’ or ‘HS Code’) in the calculator. 

Step 2. Next, you need to select the origin of the goods, i.e. Mexico in our example. The calculator will now require that you provide the value of the goods delivered to the United Kingdom. 

Step 3. The calculator is now able to work out the different rates of duty available to you. 

In our example, the ChamberCustoms calculator would tell you that there is a preferential rate of 0% for Mexico together with the other rates of duty available for non-originating products.

Assuming the information you provided is correct, and the required supporting documentation is available, the calculator will provide you with an estimated calculation of the duty payable.  

What does the customs duty calculator not do?

This calculator will not help you understand where your goods originate from and what Rules of Origin apply. Furthermore, the calculator will not be able to tell you about quotas or special procedures that could be available to minimise your overall tax bill. You can speak to our Customs Experts for advice and support. 

Fun fact: 

The Latin phrase “Erga Omnes” has been replaced by HMRC with the more friendly expression ‘All third countries’. 

Erga Omnes is a Latin phrase that means "towards everyone in equal measures", indicating a rate applicable to any country with no distinction.

Why has ChamberCustoms created this customs duty calculator for UK imports?

Now that the UK has left the EU Common Market, any goods coming from abroad will most likely attract duty and VAT.

This fact concerns traders, businesses and private individuals buying goods from other countries. 

When comparing prices, you will now need to factor in import taxes.

ChamberCustoms wants to help traders keep trading, simplifying tasks as much as possible. As a starting point, you can use our calculator to quickly work out what needs to be paid to HMRC.  

We believe our calculator can assist anyone importing goods, from a one-man-band to a large corporation. So, whether you are a UK import business, a UK small business, a UK large business or a private individual, we hope you can benefit from our calculator. 

Please note that this calculator only understands the duties payable in the UK. It’s not going to help you work out what duty may be expected in a foreign country to import goods from the UK into other countries.  

  • Yes, you can.

  • Northern Ireland is different from the rest of Great Britain because the territory of Northern Ireland is at the same time part of the United Kingdom and the EU Customs Union. If you're importing goods into Northern Ireland from the rest of the world, there is no difference to goods imported into Great Britain.

    If you're moving goods from the EU27 into Northern Ireland, there is no duty payable because Northern Ireland is considered part of the EU Customs Union.

    However, whenever you move goods from Great Britain (GB) to Northern Ireland (NI), you're moving goods into the EU Customs Union. Since there are no borders between Northern Ireland and the Republic of Ireland, EU duty may become payable at the point of introduction into Northern Ireland.

    ChamberCustoms can assist you with your GB-NI movements.

  • Northern Ireland is part of the EU Customs Union whereas Great Britain is not.
