HMRC - Alerting traders about using CDS

Businesses that import or export goods outside the EU will need to prepare for the new service for declaring these.

HM Revenue and Customs (HMRC) will begin a phased launch of the Customs Declaration Service (CDS) in August 2018. CDS will replace the existing Customs Handling of Import and Export Freight (CHIEF) system, with all declarations taking place on CDS from early 2019.

CHIEF currently processes declarations to facilitate the international movement of goods between the UK and non-EU countries. CHIEF will continue to run for a time to aid the transition to CDS.

Why CDS is replacing CHIEF

CHIEF is one of the world’s largest and most sophisticated electronic services for managing customs declaration processes, but it’s nearly 25 years old and can’t be easily adapted to new requirements.

The decision to replace CHIEF with CDS was made before the EU referendum, however CDS will be scaled to handle any potential increases in the volume of declarations that may result from the UK’s exit from the EU.

Alerting importers and exporters about using CDS

HMRC is currently building and testing CDS with industry, software providers and Community System Providers (CSPs). CSPs operate computerised inventory systems that control the physical movement of import and export freight at UK ports and airports.

CDS will be phased in between August and early 2019, with CHIEF continuing to run during this time to aid the transition. Importers, exporters or their agents will be informed by their software provider when they need to provide the additional information in order to start making declarations on CDS.

To keep informed about CDS, please send your name and email address to communications.cds@hmrc.gsi.gov.uk to register for email updates.

The updates will provide regular information on CDS and any preparations you may need to make ahead of CDS going live.

There will also be regular updates about CDS on GOV.UK and through trade associations.
