HMRC Support Information; Northern Ireland; Non-EU Trade

Many have submitted questions that require expertise on business-specific matters under HMRC’s remit. I am conscious that we don’t have the level of expertise that will allow us to help you in a timely manner given the urgency of issues that you/your members are dealing with. I have therefore included the following contact information for the support provided by HMRC.

HMRC for customs, international trade and technical support

Customs & International Trade (CIT) Helpline – 0300 322 9434

The helpline is the main route for customers with general customs queries. Capacity on this team has been scaled up following the end of the Transition Period. We have been advised that colleagues on the helpline are able to handle the vast majority of operational queries including general calls about NCTS and GVMS. The helpline opening hours are Mon-Fri 08.00-20.00, weekend 08.00-16.00 and have a Webchat capability access via gov.uk.

Technical support

For support with specific systems we have the following:

  • CDS submission enquiries - You can email HMRC about issues with electronic CDS submissions to cds.operations@hmrc.gov.uk. Emails are monitored Monday to Friday: 9 am to 5 pm.

  • CHIEF Error codes - Not all of the error responses currently have a solution. If you find an error response that doesn’t have a solution or you need clarification then please email chief.operations@hmrc.gov.uk. This will help HM Revenue and Customs to improve the service. You can also email if you need information on CHIEF error code responses that haven’t been included on the trade version of the help text.

  • NCTS Technical questions – Customers with questions around a specific consignment that is already live in transit can contact the NCTS.helpdesk@hmrc.gov.uk. As these queries may be more time-sensitive.

Outside of this, HMRC has also set up a dedicated Technical e-mail account monitored by an expert team and with access to a range of HMRC support if required. This Helpdesk will be monitored during business hours and HMRC colleagues aim to respond to operational technical questions within 48 hours. Please send a request for help to technicalcustomssupport@hmrc.gov.uk 

National Clearance Hub

Across all customer groups, the National Clearance Hub supports border movements and operates 24/7. The email address for NCH is nch@hmrc.gov.uk.
