The US has introduced additional tariffs on goods imported from outside of the USA. This includes on goods from the UK and the EU. Imports into the USA from UK will be subject to a 10% tariff and EU will be subject to a 15% tariff.
What is a Tariff?
A tariff is a tax imposed by a government on goods that are imported into a country. This tax is typically a percentage of the value of the imported goods. Tariffs are used by countries to regulate trade, protect domestic industries, and generate government revenue. When goods are imported, the company responsible for bringing those goods into the country must pay the tariff at the time of importation.
Tariffs are determined by the commodity code and country of origin of the goods.
What does this mean for Northern Ireland exports?
Under the terms of the Withdrawal Agreement between the UK and EU Northern Ireland continues to remain part of the UK customs territory. This means that Northern Ireland exports to the United States will be subject to the 10% tariff alongside the rest of the UK.
For more information on NI Exports please see this Research Briefing on US Trade Tariffs from the House of Commons Library.
What does this mean for Ireland exports?
Irish goods that are in the impacted classifications being exported to the USA will be subject to the 15% duty being introduced on the European Union.
For more information on Irish exports please see this European Commission explainer.
What does this mean for imports from the USA?
At this stage there are no changes regarding requirements for importing into either Northern Ireland or Ireland from the USA. Should either the UK or EU decide to introduce retaliatory measures this may change.
Are there any sector specific requirements?
Whilst most products are subject to the additional tariffs, the below outlines further sector specific changes:
- 25% tariff on UK origin aluminium and steel
- A 50% tariff on EU origin steel and aluminium imports to the US
- Tariff exemption on UK origin aerospace goods.

Where can I find more information on tariffs?
