Brexit for businesses 

From 1 January 2021, goods imported or exported between Finland and the UK must be declared to Customs. Businesses now observe the same rules, restrictions and customs formalities in their trade with the UK as with other countries outside the EU, that is, so-called third countries.

  1. identification and authorisations. You should reserve time to apply for these. 
  2. An EORI number. You need the number for most customs declarations and when applying for authorisations.

  • If Union goods arrive in the customs territory of the EU after this time, and their transfer from the UK has started on 31 December 2020 by 00:00 CET (01:00 Finnish time), they will be treated as Union goods. Customs must be presented with proof of the starting time of the transfer of goods (for example, a transport contract). Read in more detail about differences between modes of transport here:

Preferential tariff treatment can be granted for your goods if they are UK-originating products complying with the rules of origin in the trade agreement between the EU and the UK. 

Preferential treatment is applied for in connection with the customs declaration, and requires that the origin of the goods is verified. In the goods trade between the EU and the UK, the origin of the goods can be verified

  • with a statement on origin in a specified format drawn up by the exporter, applying to one or more consignments, or 
  • through the importer’s own statement about the origin, the so called “importer’s knowledge”. 

Importer’s knowledge does not require any separate statement or certificate, but the request for preferential treatment must be based on information and documentation about the origin of the goods that has been received from the exporter and that is in the possession of the importer. If necessary, the importer must be able to prove to Customs that the goods meet the criteria for preferential treatment in accordance with the rules of origin.
