April 20 (UPI) -- DHL Express announced it will suspend deliveries of more than $800 in response to cost increases and U.S. Customs regulations brought on by the Trump administration's tariff plan. "This change has caused a surge in formal customs clearances, which we are handling around the clock," the company said in a release . DHL said the deliveries will stop temporarily on Monday "until further notice," it said, adding that business-to-business shipments will continue but may face delays.
