We have bought goods from a British supplier but the goods arrived in Finland under T1 status, why?

European customs legislation does not allow the delivery of export goods on irregular vessels. This type of shipment is not considered to be normal European freight (status C) if the shipment’s final destination is outside of the EU. The export declaration closes in the port of departure and the shipment arrives in Finland under T1 status. This situation typically happens with a shipment going from Great Britain and Ireland to a final destination in Russia. For the end consignee, this status change creates some additional transit costs.
What to do to avoid it?
Please ask us to organize delivery from Great Britain or Ireland or ask your transport company if they can deliver goods in C-status.
