All member states are faced with many legal changes, which come our way as a result of the implementation of the UCC. The Netherlands is no exception. AGS will make way for DMS. In the meantime, plans have been shifted around quite a bit, but it is now clear that before the end of 2023, all declarants will have to submit their declarations via DMS.

Stream Software is pulling out all the stops to transition its Dutch customers to the new procedures. The transition to DMS is being rolled out in phases. Below is the latest state of affairs officially communicated by Dutch Customs:

  • Starting no later than Dec. 1, 2023, you must file returns using DMS, and AGS will no longer be supported for new returns.
  • Do you currently file declarations through Venue? As of December 1, 2023 at the latest, Venue will no longer be supported and you will have to file declarations using DMS.
    Do you want to use the exemptions of Article 23 and/or 25 for e-commerce declarations up to €150? If these declarations also meet the conditions for using the reduced dataset (H7), you can submit them in DECO. Stream Software supports e-Commerce shipments in DECO within our separate cloud application!  
  • If you are an authorization holder Registration in the Declarant's Administration (IIAA - DMS4.1) for the customs procedures of release for free circulation, active distribution, temporary importation, end-use or customs warehouse, the way of making declarations to Customs is going to change. The current declaration systems and procedures GPA and SPA will be implemented in phases and must be completed by January 1, 2024.
  • The audit file has been separated from the DMS4.1 process. Stream Software has signed up to co-develop this new procedure as a pilot. We are committed to informing everyone as best we can.

Backgroundand modifications

As in Belgium and Luxembourg, the UCC (Union Customs Code) is behind these changes. The new procedure is built from a new European data model. Because of this, Stream Software will develop a completely new module, to make anyone who prepares Dutch declarations compliant.

As in other European countries, the paper declaration, currently known as the Single Document, is disappearing in the Netherlands. In order to guarantee some grip, Stream Software developed its own layout which is made available within the application.

The terminology regarding the various procedures and customs documents will also change. The EUAH, IMAJ or other known documents will cease to exist. Here again an overview of the new customs procedures:

  • H1: Declaration for release for free circulation and Special procedure -- specific use -- declaration for end-use 
  • H2: Special procedure -- storage -- declaration for customs warehousing 
  • H3: Special procedure -- specific use -- declaration for temporary admission 
  • H4: Special procedure -- processing -- declaration for inward processing 
  • H5: Declaration for the introduction of goods in the context of trade with special fiscal territories 
  • H6: Customs declaration in postal traffic for release for free circulation 
  • I1: Import Simplified declaration 
  • I2: Presentation of goods to customs in case of entry in the declarant's records or in the context of customs declarations lodged prior to the presentation of the goods at import 

More information on this can be found at the following TAXUD website, among others: https: //

An additional change is found in audit findings. Control findings are processed differently with DMS. In AGS, Customs always 'corrected' the declaration. With DMS4.0, the declarant must deliver the corrections himself, after he has received a message with the control results from DMS. Goods are not released until the 'corrected' declaration has been fully processed by Customs.

Impact on Customs Streamliner®

Behind the scenes, all tables were rebuilt based on the European data model. DMS is built from the UCC (Union Customs Code). Because a new module had to be built completely, Stream Software developed new screens, of course in the well-known pragmatic structure. Note a higher resolution and a more logical structure of the different fields.

Within the declaration systems, the documents are split up. Whereas in the past Vak44 was often used as a summary of all documents to be declared, within DMS4.0 these must be split up (transport, additional, authorizations, previous, supporting). This split is very well explained in earlier documentation prepared by Customs Netherlands. Also, the DV1 fields have been replaced by new terms. For example, transport insurance & other are now in 1 field.

Stream Software will later communicate further about the changes within DMS4.0, including the new fields that will be introduced. In any case, multiple relationships (buyer, seller, exporter,...) will have to be entered.

Status update

Meanwhile, the entire Stream Software team is working diligently to get the new modules ready on time. Stream Software is also part of a working group to discuss the tests in the BTO. Together with some pilot customers we continue to fine tune the changes in the application through several test sessions.

After consultation with Dutch Customs, Stream Software will map the phases classified by Customs for all customers, in order to compile a planning to go-live from there. Users of Customs Streamliner® therefore do not need to complete the planning tool. Stream Software communicates target dates to everyone as soon as possible.

Stream Software will continue to communicate in detail around further changes within the DMS pathway.
