Attachment Upload

The Attachment Upload service (previously Web Liitu) is used by customers of operator-based and direct message exchange within import, export and transit as well as by users of the Export Declaration Service, the Transit Declaration Service and the Customs Warehousing Declaration Service. Attachment Upload is not intended for users of the Import Declaration Service, as they should still submit their attachments to Customs via the Import Declaration Service itself.  

When Customs requests additional information, users can also, in addition to Attachment Upload, submit attachments via the VYVI secure mail service or by e-mail.

You can speed up your transactions by sending documents in advance

Using Attachement Upload, customers can send attachments to Customs in advance, thus speeding up the processing of their transactions. The attachments should pertain to electronic customs declarations submitted to Customs.

Customers can also use Attachment Upload to submit attachments requested by Customs.

Service disruptions and user support

If Attachment Upload is not available, attachments requested by Customs can be sent to the Electronic Service Centre by e-mail or using the VYVI secure e-mail service. During maintenance downtime and disruptions it is not possible to send attachments in advance. Only attachments that have been requested by Customs may be sent by e-mail or VYVI secure e-mail. When sending attachments by e-mail or VYVI secure e-mail, a unique identifier is to be provided for the declaration, such as the MRN or import transaction identifier. (Suomeksi tässä typo: ‘lmoituksen yksilöivä tunniste’)

In case of disruptions, we ask you to primarily contact the service number or e-mail address which you would normally contact in matters concerning completion of declarations.
