CDSSG11020 - Step-By-Step Guide, Step 6 - Differences between CHIEF and CDS Additional Information Codes

Unlike CHIEF, AI codes on CDS are declared at item level only, with the exception of AI code RRS01.

AI code RRS01 is used for goods being declared at Goods Vehicle Movement System (GVMS) locations (see Appendix 16S for locations that use GVMS). It is the only AI code that may be declared at header level.

Appendices 1 and 2 (for the specific Movement Type) and the full AI code list (in Appendix 4) must be used to identify the 5-digit code to be used to declare the specific Additional Information.

CHIEF code lists must not be used as the code lists for the two systems are different.

  • Some CHIEF codes have not necessarily been carried forward to CDS as they have been replaced by specific data elements, for example CHIEF AI code GRNTR was used to declare a Guarantee Reference Number. Guarantee Reference Numbers in CDS are declared in DE 8/3 instead.
  • Some AI requirements that do still exist in CDS use a different code to CHIEF, for example Single Transport Contract (STC) details were declared using AI code STC99 on CHIEF, Ai code 30500 is used in CDS.
  • Some AI codes that exist on both systems may be used for a different purpose in CDS. For example, GEN24. On CHIEF, GEN24 is used for the name and address of the public or private scientific, teaching or vocational training establishment who will be using the temporarily imported goods. On CDS, GEN24 is used for the name and address of the prospective buyer of the goods temporarily imported for sale on approval.

It is therefore important that the CDS AI code list is used to avoid the incorrect code being declared for the type of additional information being provided.
