On Jan. 21, the German logistics group DB Schenker resumed shipments to the U.K. from the European Union after having suspended them for over a week due to the red tape introduced after the U.K. left the single market on Dec. 31.

The company, which is owned by the German railway company Deutsche Bahn, had suspended shipments on Jan. 13 on the grounds that most orders it received did not respect the new post-Brexit customs rules.

At the time, DB Schenker had indicated that only 10 percent of the orders had complete and correct paperwork. The company explained that incomplete documents delayed shipment and prevented it from accepting other orders. It added that it has worked jointly with its clients to conform to the new regulations and will only accept orders accompanied with a minimum level of correct paperwork.

The U.K. and the EU have reached a trade agreement, but the new paperwork has caused significant problems for companies. There have been complaints about customs data, rules of origin and the introduction of value-added tax on low-value goods exported to the U.K.
