This Appendix provides details of the codes to be used to provide additional information in Data Element (DE) 2/2 of the customs declaration or clearance request. The completion of codes will be determined by the:
- Procedure or Additional Procedure Codes used in DE 1/10 or 1/11
- commodity code details declared in DE 6/14 to 6/17 or
- CDS Declaration Completion Instructions
The Additional Information (AI) codes which may be used in DE 2/2 are specified below along with the details to be entered on the declaration or customs clearance request.

Where the completion rules for a specific AI Code in Appendix 1: DE 1/10: Requested and Previous Procedure Codes (https://www.gov.uk/government/publications/appendix-1-de-110-requested-and-previous-procedure-codes-of-the-customs-declaration-service-cds) and Appendix 2: DE 1/11: Additional Procedure Codes (https://www.gov.uk/government/publications/appendix-2-de-111-additional-procedure-codes-of-the-customs-declaration-service-cds) specify different rules to the completion instructions shown in this document, the rules specified in Appendices 1 and 2 take precedence.

The Codes are split into:
- Appendix 4A: Union Codes which may be declared on customs declarations or customs clearance requests
- Appendix 4B: National Codes which may be declared on customs declarations or customs clearance requests
Where a single goods item requires both Union and National AI statement codes declared in DE 2/2, any Union Codes (beginning with a number) must be declared first.
