Customs will set up a transition period until 16 June 2025 for message declarants in deploying new exit messages

Customs will start using the new exit declarations on 24 May 2025

If a message exchange customer is not able to complete the testing of declarations by 24 May 2025, message declarants will have until 16 June 2025 to deploy exit declarations. The transition period is different to the one announced previously. You do not need to apply for separate authorisation regarding the transition period. Instead, the transition period applies automatically to all message exchange customers who submit exit declarations. 

Message exchange customers are required to inform the customer testing official at Customs about the date when their companies will start using the declaration messages. If a message exchange customer uses an IT service provider in message communications, such a company must notify Customs about the date of deployment by email to UCC@tulli.fi.
