DHL Express has suspended deliveries to the US for packages over $800 due to increased customs regulations following new tariffs introduced by the Trump administration. This change, effective immediately, aims to address concerns about illicit shipments from China, but packages under $800 will still be accepted until further restrictions are implemented on May 2, impacting companies like Shein and Temu. The new measures are part of efforts to combat the synthetic opioid crisis linked to shipments from abroad, prompting backlash from entities like Hongkong Post.
