Changes in message exchange

For amendments, use the form 934e “Application for message exchange with Finnish Customs” or the online service “Applying for a message exchange authorisation”. Changes can include:

  • changes in the software your company uses (may require repeating the testing with Customs)
  • your company wants to extend the use of message exchange to include another system
  • your company changes the service provider used in direct message exchange (if the company is a message declarant, you must notify Customs of the change of service provider, and the new service provider must have an authorisation for direct message exchange)
  • change of the operator used
  • your company wishes to give up its status as a message exchange customer due to, for example, corporate arrangements.

A company must submit a new application for message exchange if its Business ID changes.
