What is the Customs Declaration Service (CDS)?

The Customs Declaration Service (CDS) is a new system introduced to replace CHIEF (Customs Handling Import and Export Freight). CDS will affect the way you create import and export declarations as its introduction looks to streamline the customs process, bringing a more modern approach to international trade through a digitised customs platform.

Since 4 June 2024, declarants must now be using the CDS system to complete and submit their declarations. Therefore, it is critical that businesses are up-to-date and knowledgeable on the new systems operation and requirements.
