Customs Clearance Systems Changing from CHIEF to CDS

customs clearance cds changes

The Customs Procedure for handling Clearances Declarations is changing from (CHIEF) to the new Customs Declarations Service (CDS).

CHIEF, which is the system currently in use and managed the process for over 25 years cannot be adapted to the new CDS requirements and therefore, will be turned off in two stages:

– Imports On the 30th September, 2022 – The option to use this procedure will end.

– Exports On the 31st March, 2023 – The option to use this procedure will end.

Brunel European clients will be migrated to CDS but not without your assistance please. We shall require additional information from you never previously requested due to mandatory changes on CDS that HMRC will require to enable your good to clear customs.

Please action the below requests to help us support you

The Brunel European team will be asking for a different set of data when processing your customs declarations – please note this will be different when compared to what has been previously requested. It is important to point out that all CPC’s (Customs Procedure Codes) will change, and some commodity codes will require additional information, this is driven by the new data requirements associated with CDS.



– You must have a Government Gateway account. You should use this account to access the Customs Declaration Service. You can register for a Government Gateway account if you don’t have one already.

– You must have a valid EORI registration.

– You must be registered to use CDS

– If you have a deferment account a new direct debit will need to be created with HMRC for use with CDS.

– Customs Comprehensive Guarantee number is required on all declarations when a deferment account is being used, if you have a deferment account we will need your CCG number to update our records.

– You will need to authorise Brunel European to use your deferment account on declarations via you Government Gateway account under the deferment options.

– CCG will also be required for Special Authorisations and Procedures, for example CFSP, inward processing relief. Special Authorisation and Procedures will also have a CDS specific authorisation number.

– HMRC have created various online documents to provide details of the changes. A communication pack detailing key differences between CHIEF & CDS can be found at the below link:
