You may also put your questions to your umbrella organisation, which also provides support in respect of communications about the coming changes.

National Committee on Trade Facilitation (NCTF, ODB in Dutch)

A feedback group with representatives of the business community has been set up with the aim of properly implementing all the changes. The changes for the business community as a result of the arrival of DMS are the subject of discussion in this group.

Check the agendas and meeting documents of all NCTF meetings (only available in Dutch)

More information about providing data

The transition form AGS and/or G(S)PA to DMS means that declarants must provide different data. You can read the announcement in the Staatscourant (Government Gazette, only available in Dutch).
