HMRC provides a number of resources to help companies trading with the EU.
If you move goods between Great Britain (GB) and countries in the European Union (EU), you might be affected when full customs controls come into effect on 1 January 2022.
If you have a specific question about importing, exporting or customs reliefs, call the Customs and International Trade Helpline on 0300 322 9434. The helpline is open from 8 am to 10 pm Monday to Friday and from 8 am to 4 pm at weekends. You can also send questions or make contact by webchat.
The Export Support Service is a new helpline for UK businesses to get answers to practical questions about exporting to Europe. The service is a 'one-stop shop' and brings together UK government information, making it easier for exporters to access advice and support.
