Submitting declarations without electronic identification


You may submit entry summary declarations or exit summary declarations for goods carried by road without any electronic identification. Other declarations can only be submitted using or KATSO ID.
Create a declaration by clicking the “Create an entry summary declaration” button or the “Create an exit summary declaration” button.
After your have successfully submitted the declaration to Customs, the movement will be allocated an MRN. This MRN must be provided to a customs officer when arriving in the country. The MRN can be printed out in the form of a barcode when submitting the declaration. It is not possible to print out the MRN at a later stage.

Submitting declarations using or KATSO ID

The identified user logs in to the Customs service using identification or mandate from the Digital and Population Data Services Agency or with Katso ID issued by the Finnish Tax Administration (a Master User ID or a Katso ID to which the role CUSTOMS-Customs clearance has been granted). For the time being, the Katso ID will remain in use in companies that cannot use identification yet. Identified users can follow the progress of the processing of the declarations at Customs. Users can also save declarations as drafts if the processing is interrupted for some reason. Older declarations can be used as templates for new entry summary declarations.
Identified users log in to the service by clicking “Log in using identification” or “Log in using Katso ID” at the top of this page.

Certain declarations require that the goods description be given with sufficient accuracy. The description is to be given either by entering the commodity code with an accuracy of at least four digits to indicate the goods heading or by providing a goods description of the corresponding heading level. The European Commission has published instructions on the correct way to submit the goods description (TAXUD/1402/2007).
Submitting web declarations is made easier if the declarant has found out in advance the appropriate goods description and heading for the goods, for example by using the TARIC database of the EU. The commodity codes can also be found in the Combined Nomenclature (CN) on the Finnish Customs website.
