US postal traffic plummeted 81% after the Trump administration ended a trade exemption on August 29th, 2025. This rule, allowing small packages under $800 to avoid tariffs, was suspended. The Universal Postal Union (UPU) reports a near halt in postal traffic to the US, with 88 operators suspending services. The UPU is working on a solution, while the White House hasn't commented. The administration justified the move as a way to combat illegal imports.
