The UK has left the EU customs union, single market, and VAT area. The Trade and Cooperation Agreement (PDF 7.44MB) (TCA) sets out the terms of UK trade with the EU from 1 January 2021. Some constituency businesses and individual constituents find dealing with the amended import and export procedures challenging. Below are the main sources of information which may help people dealing with constituency casework questions about customs rules.

This document is intended to be a general overview of some of the issues arising from trade with the EU. It is not a comprehensive guide to all aspects of trading with the EU and does not cover the circumstances of any specific case.

Tariffs and rules of origin

The UK-EU TCA secures zero tariffs and quotas on goods moving between the EU and UK, provided those goods meet the rules of origin (RoO). The RoO determine the “economic nationality” of a good based on where the products or materials (or inputs) used in their production come from. They prevent goods manufactured in third countries being routed through the UK (or the EU) to avoid paying third country tariffs.

To benefit from the TCA zero tariff, businesses must show the origin of their goods. A product qualifies as ‘originating’, if it is ‘wholly obtained’ in the UK and EU, or has been substantially transformed in one or both markets. That is why, as reported by the Financial Times, businesses that re-export goods from third countries with little or no further processing, may still face tariffs when trading with EU Member States.

Rules of origin can be onerous. In some cases, the rules are specific to particular products. Some businesses cannot or do not wish to claim zero tariff because of the complexity or cost of the paperwork. Research by the UK Trade Policy Observatory shows that during the first part of 2021, a substantial number of businesses did not claim zero tariffs when exporting to the EU.

UK-EU customs processes

Customs controls ensure duties are paid on goods moving across the border, and check compliance with safety, security, health and environmental requirements.

The EU has introduced full customs controls from 1 January 2021.

The UK Government has been phasing in border controls for goods imports from the EU over 2021. For example, customs declarations are now required for all goods.  The Government was planning to introduce the remaining controls by July 2022. This would include further health certification and sanitary and phytosanitary (SPS) checks on agri-food products, physical SPS-checks on EU imports at designated Border Control Posts, and a requirement for safety and security declarations. However, on 28 April, the Government announced the remaining import controls on EU goods will not be introduced. It is seeking digital solutions for the border and exploring new technologies “to reduce friction and costs for businesses and consumers.” The new target date for a reassessed import control regime is the end of 2023.

The Government’s Border Operating Model (June 2022) is a comprehensive guide on customs processes, both for imports from and exports to the EU. An Institute for Government explainer contains an overview of customs formalities for UK-EU trade.

Steps for businesses

Businesses need to familiarise themselves with new processes. These include: preparing to make customs declarations, knowing how to classify their goods correctly, and following safety and security requirements for their goods.

Making customs declarations

From 1 January 2022, traders must submit customs declarations for all goods exported from and imported into the UK (excluding those from Ireland). In some cases, a business may submit a simplified declaration.

Classifying goods

Traders are responsible for correct classification of goods and recording of the origin of goods. Incorrect commodity codes or inaccurate recording of origin in customs declarations may mean that the wrong amount of tax or duty will be charged. Traders may classify their goods themselves but HMRC often advises getting help from customs intermediaries to ensure that goods are classified correctly. More information is on GOV.UK: Claiming preferential rates of duty between the UK and EU.

Businesses importing goods can check the applicable UK tariff duties and VAT rates with the help of the HMRC Trade Tariff tool.

Follow safety and security requirements

The EU requires safety and security declarations on imports from and exports to the UK. The UK Government does not currently require these declarations for imports from the EU. When exporting from Great Britain to the EU, a trader generally has to make an exit summary declaration.

Expert help

Submitting customs declarations can be complex. The Government Border Operating Model (PDF 3MB) recommends (p22) that businesses use a customs intermediary who can do this on their customers’ behalf. HMRC has lists of customs agents and fast parcel operators.

Further information

Traders can find information on customs and tax rules through various UK government channels:

The European Commission has a Taxation and Customs information website. In individual cases it is advisable to consult the involved EU Member State’s customs authorities.
