Proofs of Union status endorsed in Poland can now be presented in the Customs Clearance Service or with the message FI332

Proofs of Union status that have been endorsed and registered in Poland can now be normally presented in the Customs Clearance Service or with a message (FI332). The error in the system has been resolved. 

The MRN of a proof endorsed or registered in Poland has the format “25PLnnnnnnnnnnnnPn”. In Finland, goods with proof of Union status obtained from Poland are to be presented in the Customs Clearance Service or with the message FI332. The presentation notification must no longer be submitted in the EU’s Proof of Union Status (PoUS) system.
