How to submit arrival and exit declarations
Arrival and exit declarations can be submitted electronically, either as message declarations or via the Safety and Security Declaration Service (AREX). To submit message declarations, you need an authorisation from Customs.
You do not need an authorisation to use the customs online declaration service. An entry or exit summary declaration for road traffic, can be filled in as an unidentified user, in that case the declaration is not saved. Submitting other declarations require that you log in with a Katso ID.
