Posti’s tips for businesses: With the United Kingdom due to leave the EU on January 1, 2021, otherwise knows as Brexit, what should you take into account with regard to sending and receiving letters and parcels containing goods?


From January 1, 2021, the UK will no longer be part of the EU’s customs tax treaty applicable to trading. When it comes to the UK, the procedure will follow that of countries such as China or Russia, which are not part of the EU. The change will also have an effect on how letters and parcels containing goods are sent and received, so it’s a good idea to familiarize yourself with it in advance.

When sending or receiving goods as a business (contract customer), please take the following tips into account from January 1, 2021 onward

  1. All items containing goods sent from Finland to the UK must be cleared through customs.
    • The letter and parcel items that must be cleared include: Priority and EMS parcels as well as international letter items containing goods.
  2. Please make sure that you know the full details of a recipient residing in the UK as well as all of the information required for an invoice/pro forma invoice.
  3. Contact Customs to request an EORI number (Economic Operators Registration and Identification System) if you don’t have one already.
  4. Apply for a VAT account (SPRN/HMRC) from the UK’s Inland Revenue if you are selling to a private person.
  5. You can find further information and instructions on the Finnish Customs’ website
  6. You can find further information and instructions on the Finnish Tax Administration’s website
  7. Parcel items and tracked goods letter items: provide Posti with the sender and recipient information as well as the information required for the CN22 or CN23 customs clearance using the sending channels (e.g., SmartShip) or using an EDI message, depending on the value of the item. Attach the customs clearance slip on the item. Attach 3 commercial/pro forma invoices to the item. Date and sign the customs clearance form to confirm the information or approve the information online.
