Customs Declaration Completion Requirements for The Northern Ireland Protocol


Last updated 8 April 2024

All businesses can now move their export declarations to the Customs Declaration Service (CDS), HM Revenue and Customs (HMRC) has confirmed.

Businesses who have yet to move their export declarations to CDS will have a transition period to move across, until 4 June 2024. After this date, customs declarations cannot be submitted through the Customs Handling of Import and Export Freight (CHIEF) service.

Remember: If you’re moving goods to or from Northern Ireland, including moving goods from Great Britain to Northern Ireland, you can use the free to use Trader Support Service (TSS) which is available to support with your declarations and provide further training and guidance. Alternatively, you can get a specialist to do your declarations for you, by using an intermediary.

If you do not wish to use TSS or an intermediary, the Customs Declaration Service can be used for your declarations.
