From AGS and G(S)PA to DMS: what will change for you?

You will soon be submitting your import, storage and export declarations, presentation notifications and your additional declarations in DMS. This page explains how this will affect you.

  • Do you file declarations with AGS? From 1 December 2023 at the latest, you will have to file declarations with DMS 4.0, the successor to AGS 3.1. However, you will need to modify your business processes and declaration system according to the modified message specifications for DMS 4.0 and take into account the modified processing of inspection findings.
  • Do you file declarations with Venue? From 1 December 2023 onwards, you will have to file declarations with DMS. Except for export declarations up to €1,000. You can continue to declare this in Venue until further notice. Do you want to use exemptions of Section 23 and/or 25 for e-commerce declarations up to €150? And do these declarations meet the conditions for using the reduced dataset (column H7 of Annex B GVo.DWU)? If so, you can file them in DECO.
  • Do you have an Entry in the Declarant's Records (EIDR, or IIAA in Dutch) authorisation for the customs procedures regarding the release for free circulation, active distribution, temporary importation, end-use or customs warehousing? If so, you must submit application notices and additional declarations via DMS before 1 January 2024.
  • 3 scenarios have been developed for this purpose as discussed in our webinar of 21 April 2021 (only available in Dutch).
    • The data requirements (the data set) for adjusting the declarations. To file declarations, use:
    • the data requirements of Appendix B of the Delegated Regulation of the Union Customs Code (UCC DA)
    • the formats and the codes of Appendix B of the UCC implementation regulation (UCC Implementation Regulation)
    • the national supplements in Appendix VIa of the General Customs Regulations
    Do you have an Entry in the Declarant's Records (EIDR, or IIAA in Dutch), customs warehouse (DE)? Read more on 'DMS: gevolgen voor vergunninghouders IIAA douane-entrepot' (DMS: the implications for a holder of an authorisation for the IIAA customs warehouse, only available in Dutch).

Stock audit file

  • Are you an IIAA holder who places those goods under the directly subsequent customs regulations with IIAA? Under certain conditions, you may be able to use what is referred to as the chain procedure. You only have to present the goods if you place the goods under the 1st customs arrangement. If you place the goods under a subsequent customs arrangement, you must enter that into the same declarant’s records to be able to use the chain procedure.
  • EIDR authorisation holders will have to start using the so-called stock audit file to exchange the inspection information previously included in the GPA. If you choose scenario 3 (chain arrangement), this is mandatory. You can download the specifications for stock audit files at

New Message Implementation Guide (MIG)

The altered message implementation guide (MIG) for DMS 4.0 and 4.1 has been published on the website of the National Helpdesk Customs at the Dutch Customs Support Centre for Software Developers.
