Difficulties with customs documentation since the UK’s exit from the European Union have pushed some road freight onto shortsea container routes, according to a freight forwarder with expertise in Eastern Europe and Russia.

FSM Logistics started a direct container shipping service to ­Tallinn in Estonia in the spring to give its usual road freight customers another option for exporting to Eastern Europe and beyond after the introduction of the T1 declaration for carrying non-EU goods via the EU.
