You can enquire about the matter by contacting the Customs registry office by email to kirjaamo(at), or by phoning 0295 527 000. The registry office will tell you the date when Customs received your claim for a revised decision, that is, the date when the application became pending.

Please note that the processing of your application takes about three months.

You can make a new (replacement) customs clearance for the right customer. Use the same tax determination date in the replacement clearance as in the original customs clearance. Send a request for repayment or remission of customs duties concerning the incorrect customs clearance to the Customs Registry Office

You can lodge an express claim if the customs invoice relating to the incorrect customs clearance decision has not yet been paid and there is at least seven days until the invoice is due. If the due date has already passed, both invoices have to be paid and a repayment can be applied for retrospectively.
