As communicated by Dutch Customs, the final effective date for the new Temporary Storage Declaration (TSD) has been postponed to 16 November 2026 at 12:00.

If you use a system connection

Changes to the message specifications remain required and additional data must be included in the declaration.

Before going live, successful testing must have taken place in the test environment, followed by a successful pilot in production.

If this has not been completed before 1 November, we cannot guarantee a timely go-live.

If you use web screens

We will contact you to agree on the exact date for the switch to the new web screens for Cargo Declaration Import.
