You can submit T-transits and TIR transits in the Transit Declaration Service.
When you’ve made a declaration in the Transit Declaration Service, you receive a reference number specific to the transit declaration. Present it at the customs office. Customs will fill in its own sections of the declaration.
Submitting a transit declaration requires the lodging of a guarantee. If you don’t have a comprehensive transit guarantee you will have to provide a cash deposit as guarantee to covers the taxes. The goods to be transited must also be presented at the customs office. At the customs office, you receive a Transit Accompanying Document (TAD), which shows that the goods have been released for the transit procedure. Only then, can the transport to the customs office of destination begin.
When the transit is discharged, Customs returns the guarantee you deposited to your bank account or you can use the comprehensive guarantee again. Read more: Guarantees
You can create a declaration either as an unidentified or as an identified user.
Unidentified users receive a declaration-specific reference number generated by the system.
Identified users can also browse their previous declarations, use previous declarations as templates for new ones and edit declarations, before the declaration is processed at Customs. Read more: How to identify yourself and grant authorisations
