DHL Express, a division of Germany’s Deutsche Post, said it would suspend global business-to-consumer shipments worth over $800 to individuals in the United States from April 21, as U.S. customs regulatory changes have lengthened clearance.

The notice on the company website was not dated, but its metadata showed it was compiled on Saturday.

DHL blamed the halt on new U.S. customs rules which require formal entry processing on all shipments worth over $800. The minimum had been $2,500 until a change on April 5.
