Customs Declaration Service (CDS) is the UK government’s new electronic system for handling customs declaration processes. CDS will replace the existing CHIEF system in the future.
HMRC is implementing the system transition from CHIEF to CDS in several stages. The system is currently tested and further developed with a small group of businesses. More businesses will move from CHIEF to CDS when more functionality has been developed.
You can register for HMRC’s e-mail notifications to be updated on the latest implementation status of CDS.
