In order to comply with the Multi-Annual Strategic Plan (MASP) and the accompanying Union Customs Code (UCC) legal requirements, Dutch Customs is developing a new declaration system, DMS 4.0, which will replace the existing AGS declaration system. This change will require technology-driven processes that can cope with the new, highly automated, real-time declarations and will be accompanied with a release of DMS 4.1, which will replace the GPA and SPA processes. C4T is aligned with Dutch Customs to ensure CAS is fully integrated with DMS by the time it will launch.

The schedule of implementing DMS 4.0 has been delayed several times due to a connection issue which was not allowing Customs to send certain duty payment information to the European Commission. But as of December 2022 it was announced that DMS 4.0 (for declarants who make import and export declarations according to the normal procedure) and DMS 4.1 (for Permit Holders IIAA) will be ready by 1 January 2024 at the latest. 

There are certain Special Procedure authorisations that are particularly helpful when trading in the Netherlands, one where you can see a significant return is the Customs or Bonded Warehouse (CWH) authorisation. This authorisation allows either a reduction or complete relief from customs duty and taxes in applicable circumstances.
