The upcoming CDS update, version 5.0.0.2, is scheduled for release on the 8th January 2026. There should be no scheduled downtime during this update.

Changes for both Imports and Exports

Supervising Customs Office ID


DE 5/27 Customs Supervising Office: A correct Supervising Office ID must be declared accordingly.

 

Should DE 5/27 be declared without an actual Supervising Office ID being declared, then the declaration will be rejected.


Document Code Requirement to be enforced

Document code requirements for the following codes

D025, D026, D027, D028, L128, L129, X828, Y257, Y258, Y688, Y689, Y690, Y768, Y769, Y886, Y887, 9EHC.

 

Document codes L128, L129, and X828 will become electronic licences effective as of release. The declarations will be rejected should an electronic document ID be declared with a non-electronic document status code.

 

Document code X001 will reject declarations if completed with an ID other than that of a CAP export licence.

 

For documents such as Export Health Certificates that are incorrectly declared against X001, they must be declared against document code 9EHC, as per the tariff, or omitted from the declaration.


Additional Information Code (AI)

SDSDE has been added to the CDS additional information code list

 

It should only be used when instructed by HMRC.

 

Freeports Location Codes

Changes are being made to the validity of Goods Location Codes that can be declared in DE 5/23 when Authorisation Type Code ‘FP’ is being declared within data element DE 3/39.

 

Should FP be declared in DE 3/39, the following changes apply to the Goods Location Qualifier (fourth character) of the Goods Location Code (GLC):

 

  • ‘U’ is no longer mandated as the fourth character of a Goods Location Code declared in DE 5/23.
  • ‘B’ is no longer prohibited as the fourth character of a Goods Location Code declared in DE 5/23.

 

For Location Codes where ‘B’ is the fourth character, such as those codes that are relating to a Customs Warehouse (CW) or inland location, it will not cause declarations to be rejected when Authorisation Type Code FP is being declared within data element DE 3/39


Goods location codes

New Goods Location Codes have been added to the CDS code list.

 

Appendix 16 will be updated accordingly.



IMPORT DECLARATION UPDATE

 

Country of Dispatch

Document codes N002, N851, 9115, C085, C640, N853, C678, C673, then DE 5/14. The country of dispatch/export must also be declared. If DE 5/14 is not completed, the declaration will be rejected.

 

This is to ensure the country of dispatch is declared on an I1 C&F to support BTMS/CERTEX validation.


The other datasets for import declarations either already mandate DE 5/14 or do not permit use with SPS goods.


Nationality of Means of Transport Crossing the Border

For Northern Ireland H1, H3, H4, H5 declarations, data element DE 7/15, Nationality of the means of transport crossing the border, is mandatory unless DE 7/4, Mode of transport at the border, is coded 2 (Rail), 5 (Mail), or 7 (Fixed Transport Installation).

 

If a Northern Ireland H1, H3, H4, or H5 declaration is submitted with DE 7/15 and DE 7/4 is not coded 2, 5, or 7, the declaration will be rejected.

 

DE 7/15 is no longer required on GB H1, H3, H4 or H5 declarations, regardless of the mode of transport at the border. These changes were delivered as part of the GB declaration simplifications in CDS Release 4.9.0.


The GB declaration simplifications require extensive amendments to the Declaration Completion Instructions, which are currently being compiled.

 

Identity of Means of Transport

For import H1, H3, H4, H5 declarations with Additional Declaration Type Codes A or D

 

If the border transport means mode code declared in DE 7/4 is not 5 (Mail) or 7 (Fixed Transport Installation), then DE 7/9 Identity of the means of transport on arrival is mandatory and must be completed.

 

If a declaration of type A or D (H1, H3, H4, H5) is submitted with a border transport means mode code other than 5 or 7, and DE 7/9 has not been declared, the declaration will be rejected.



EXPORT DECLARATION UPDATE


Statistical value update

Data Element (DE) 8/6 is mandatory on Export declarations unless Additional procedure Code 3NS is declared.

 

This applies to export declarations B1, B2, B4 & B1MOU with Additional Declaration Type Codes A, D, Y & Z


If DE 8/6 is not completed for these Export declarations, the declarations will be rejected.


Export document codes

Document Codes - C651 and C658


When either is declared in DE 2/3 for an item on a declaration, all goods on that declaration must also contain the document code C651 or C658.


The document Codes declared on each goods item do not have to match.

For example, Document Code C651 could be declared against items 1 and 2, and Document Code C658 against item 3 DE 2/3.


If one of the Document Codes C651, C658 is entered in DE 2/3 for a goods item, but any other goods item on the declaration does not contain one of these document codes, the declaration will be rejected.


If a consignment includes items covered by an Electronic Administrative Document/Fallback Document and other items that don’t have either, separate declarations will be required.


Document code 90W8

When Document Code 90W8 is entered in DE 2/3 for an item, it must be present on all items on the declaration.


Should 90W8 be declared on an item, but is not present on any other items on the declaration, the declaration will be rejected.


Separate declarations would be required if some items are covered under 90W8 and others are not. Those not covered would need their own customs declarations.
