Negation codes are used to indicate products that are not subject to any import or export restrictions. For example, if an imported toy does not contain cat or dog fur, which are prohibited items, the negation code for the toy is Y922.

Negation codes and other conditional and additional codes can be checked in the EU TARIC database for each commodity code.

The Import Declaration Service can be used by both Customs’ cash and registered credit customers. Using the Service requires a Katso ID, which is granted free of charge by the Tax Administration. 

Detailed information on importing and instructions for different import clearances, can be found on the Import page.

To submit a customs declaration, you need:

  • an arrival notification from the freight carrier with information on the consignment:
    • the date of arrival
    • the weight of the consignment (not always indicated)
  • the arrival ID for a postal consignment
  • in freight consignments, the previous document is generally the MRN of the AREX + the goods item number
  • information on where the goods are located
  • a trade invoice or some other proof of the value of the consignment
  • a possible freight invoice
  • other documents, licenses and certificates connected to the consignment 
  • the commodity code of the product.

A postal consignment has to be cleared and the taxes paid within 20 days. Also note that if you are paying the customs clearance decision by any means other than through the Import Declaration Service, the payment may take up to 2 to 3 days to reach Customs’ bank account. Even though the customs invoice has a 10-day term of payment, taxes need to be paid in such a manner that the payment shows in Customs' bank account before the 20-day storage time ends.

Posti will automatically return the consignments that have not been cleared and paid within the time limit, and will not grant extensions to the storage time.

Regarding other than postal consignments, ask the freight carrier about the time limit for customs clearance if necessary.

You can submit a declaration regarding a freight consignment in advance, if you have the MRN of the previous document (e.g. AREX or transit).

Observe that you cannot submit an advance declaration for a postal consignment.

The declarant, who submits a customs declaration or on whose behalf it is submitted through the Import Declaration Service, must personally archive all documents pertaining to the import.

Yes, if you have provided your email address in your operator’s information. It pays to always provide the email address, since requests for further information and other possible enquiries/notices are sent by email to the customer.

After you have saved it, the draft can be found on the front page under the heading ‘Luonnokset’ (Drafts).

When submitting import customs declarations in the name of a company, you can log into the service using either a Master User ID or a Katso ID created by the master user of the company and to which the role CUSTOMS-Customs clearance has been granted.

If your company needs several Katso IDs for customs transactions by employees other than the master user, do this:

  • The master user of the company has to set up a Katso Sub-ID for another person.
  • The holder of a Katso Sub-ID must upgrade it into a Katso ID. At the same time, this person can also print out a list of one-time passwords.
  • The master user of the company grants an authorisation containing the role CUSTOMS-Customs clearance to the employee’s upgraded Katso ID.
  • Before the ID is enabled, the employee who has been granted an authorisation must accept it by logging into the Katso Management Application with their own identifier.

Taric is the EC’s common customs tariff, which is used e.g. to define Union taxes and payments. The Taric codes are located in the Taric database. It contains a nomenclature, code numbers and additional coded, amounts of customs duties to be implemented, other bases for charges as well as information needed regarding administration or actions to be implemented on import and export.

The Taric database

Please select the appropriate nature of operator. If your company is Finnish, choose company/Finland.

It is a reference number you choose yourself to specify a consignment in your company, for example, a number of a trade invoice.

An item to be cleared are goods declared with one customs declaration.

Incoterms, or delivery terms, are trading conditions of the International Chamber of Commerce (ICC), which define the responsibilities of the buyer and seller regarding the delivery, the goods and costs. Enter the delivery term of the trade invoice to the customs declaration.

The statistical value refers to the price of goods including the additional import costs occurring outside the borders of Finland and in export, the additional cost inside the borders of Finland, such as freight and insurance costs and, when necessary, shipments free of charge that are not included in the price. The price of partly or completely gratuitous goods is determined according to the price that would be acquired upon selling the goods. The statistical value does not include taxes implemented in Finland, such as: customs duties, VAT, excise duty, import costs and other taxes and/or export refunds with similar effect.

The value of the goods is declared as the statistical value of goods imported or exported for processing under contract or to be used for repairs. When re-exporting goods, the costs for wages etc. in accordance with the trade invoice, are added to the value of the goods as well and freight and insurance costs up to the Finnish border.

The information about summary declaration/previous document has to do with the supervision of customs clearance of goods upon arrival in the customs territory.

  • the arrival ID is entered for postal consignments
  • the previous document in freight consignments is generally the MRN of the AREX + the goods item number. The freight carrier notifies you of the previous document to be submitted

When you fill in the customs declaration, you can choose the right code in the drop down list of the section in question.

The country of origin is the country where the goods are from i.e., were they were produced or manufactured. If goods have undergone manufacturing or processing in at least two countries, the country of origin is the country where the last significant and economically motivated manufacturing or processing was performed and which resulted in a new product. For example, packaging, sorting and other comparable small scale handling is not considered manufacturing.

However, the dispatching country is entered as the country of origin in accordance with the statistical directives in the following cases:

  • the country of origin is not known (and cannot be established)
  • returned goods and other goods originating in the Union
  • goods belonging in chapter 97 of the customs tariff
  • after outward processing (nature of transaction stating codes 51, 52 or 53 in box 24) for imported goods.

Add the total value of the goods in the consignment. If the cost of freight and other costs are specified separately, the freight and other costs are specified separately for each goods item.

Please note that you do not need to attach documents to an electronic customs declaration. If necessary, Customs sends a separate request by email to have documents delivered for inspection. If necessary, you can send the requested documents by email to the email address mentioned in the request.

Goods subject to charge and free goods are declared with separate customs declarations.

The EU has a customs union agreement with Turkey which involves the import and trade in most so-called industrial products. Industrial products imported from Turkey are entitled to duty-free treatment if the goods have been in free circulation in Turkey. The country of origin of the products is irrelevant. Justification for duty-free treatment of customs union products upon import, is proven with an A.TR. goods certificate.
