Message exchange

Message exchange between a business and Customs refers to electronic transfer of data using messages of a specified format.  Message exchange is the declaration method of choice if the business has a large number of declarations that contain several goods items.

Message exchange can be used in import (import customs declarations), in export (export customs declarations), in declaring the entry and exit of goods, in transit (T1 and T2 transit declarations and electronic TIR Carnet declarations), in Åland tax border declarations and in statistics declarations concerning intra-EU trade.

Requirements for message exchange:

  • Data communication links for transmitting messages.
  • Software for creating and sending declarations to the various systems of Customs.
  • Authorisation for message exchange granted by Customs.
  • Testing the applications and data communication links with Customs.

Direct message exchange 

Direct message exchange is web service through which businesses can send messages in XML format to Customs directly from their own data systems.  

The benefits of and requirements for direct message exchange: 

  • Direct message exchange is a fast, reliable and economical service channel through which customs declarations can be sent without enlisting the services of a separate operator as a go-between.
  • Direct message exchange requires that a server certificate be obtained from the Population Register Centre for generating and transmitting messages.     

Message exchange via an operator

In a few years, Customs will no longer be providing the option of sending messages via an operator.

In this form of message exchange, businesses can send messages to Customs in the data communication network via certain operator companies approved by Customs.

The messages used in operator-mediated message exchange can be in EDIFACT or XML format. Using this method of lodging declarations requires that the business enter into an agreement with the data communications operator. The operator is responsible for ensuring that the communications that it provides are reliable both in terms of data security and availability. The operator has the task of identifying the customer and checking that the customer has an authorisation to use direct message exchange with Customs.
