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.  

To lodge customs declarations, your business needs   

  1. Suomi.fi 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. 

Guidance on how to start lodging customs declarations  

Goods moving at the turn of the year   

  • If Union goods arrive from the UK in the territory of the EU before 1 January 2021, 00:00 CET (1 January 2021, 01:00 Finnish time), they will keep their Union status.
  • 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:
