Customs Declaration Service

This page brings together information about the new Customs Declaration Service (CDS).

About CDS

The Customs Handling of Import and Export Freight (CHIEF) is being replaced by CDS, a modern and flexible system that can handle anticipated future import and export growth.

HMRC began phasing in CDS from August 2018, starting with a group of importers who make certain types of Supplementary Declarations. From November 2018 remaining importers will start to move over to CDS. Exporters will follow when export functionality is delivered in March 2019.

For updates on CDS, register for the HMRC Business Help and Education email service.

The CDS updates will be under the education topic ‘trading with other countries’.

What is changing

If you import or export outside of the European Union (EU), there will be differences in the information you need to provide with your declarations. This is due to changes to the UK Trade Tariff required by the Union Customs Code (UCC).

You will need to refer to the CDS version of the Trade Tariff to make declarations. The exports tariff will be available later in the year. If you use an agent for customs declarations you may need to provide them with more information as a result of changes to the tariff.

CDS will benefit businesses by providing the capacity to include more items per declaration, potentially reducing the number of declarations you need to make. And for the first time you’ll be able to access information about your imports and exports through your Government Gateway ID and password.

There will also be changes to Duty Deferment and Flexible Accounting System accounts, and the process for getting an EORI number. Further information about these changes will be available later this year.

More information will be added to this page as the programme develops.
