(Bloomberg) -- DB Schenker, a major logistics company owned by German rail giant Deutsche Bahn AG, suspended deliveries to the U.K. due to “significant” problems caused by post-Brexit red tape.

The company, which has about 76,000 employees in 2,100 locations, “has been forced to put a temporarily hold on the acceptance of new consignments for shipment” to the U.K., it said in an e-mailed statement. DB Schenker said only about 10% of goods it had been commissioned to ship were accompanied with accurate customs forms.

DB Schenker’s decision is the latest example of disruption to cross-border trade following Britain’s exit from the EU’s single market and customs union. On Jan. 8, parcel delivery firm DPD also temporarily suspended deliveries into the EU due to high error rates with new customs forms.

Trouble with clearing customs has been one of the major early issues of Brexit, with some companies facing days-long delays to move their goods. Deliveries into the EU from Britain now require customs declarations, and DB Schenker said customers should submit documents such as compliant invoices, proof of origin of their goods and their commodity codes.

Firms are also grappling with new restrictions such as having to register to pay VAT in the EU, and filing health certificates to export animal products. Exports of fish have been badly affected by the extra bureaucracy.
