Import declarations must now be made through the Customs Declaration Service (CDS).

While most export declarations can move to the Customs Declaration Service by Saturday 30 March 2024, we understand not all customers may be able to migrate by then. For this reason, you will have up to three months to migrate from when the Customs Declaration Service becomes available for your exports.

This guidance supplements the Customs Handling of Import and Export Freight (CHIEF) and Customs Declaration Service trade tariffs when making declarations. It should be read in conjunction with the current versions of the UK Trade Tariff: Volume 3 for CHIEF and the CDS Declaration and Customs Clearance Request Instructions (UK Trade Tariff: volume 3 for CDS).

It provides high level information on the customs requirements and includes the specific changes and declaration completion requirements where they differ to the current published Tariff instructions.

You should make sure that the instructions specific to the declaration system being used are read.
