Arrival and exit fallback procedure

When there is a disruption in Customs' or the customer's system, part of the declarations to be submitted via the AREX system can exceptionally be submitted in paper format. In addition to the fallback procedure document, an electronic declaration is submitted retrospectively.

Customs informs the customer if there is a service interruption in Customs’ systems. Subsequently, Customs informs whether or not a fallback procedure can be used. If there is a service interruption in the customer’s system, the customer must request permission from the Customs Electronic Service Centre to use the fallback procedure: spake.arex(at)

Message declarants can use online declarations as the fallback procedure without any separate authorisation.
