More than 30 nations have suspended some parcel shipments to the United States in preparation of new tariff rules going into effect this week.

A UN agency responsible for the postal sector said Aug. 26 more than two dozen of its member states had suspended goods consignments to the United States, citing uncertainties over new tariff policies starting on Friday, Aug. 29, and their potential effects on transit services.

The pauses are in response to President Donald Trump's decision in July to sunset the "de minimis" trade agreement, an exemption that for years allowed packages worth less than $800 to enter the U.S. duty-free. In 2024, de minimis shipments coming into the United States were valued at more than $1.36 billion, according to Customs and Border Protection.

De minimis: Key trade loophole ends this week. What it means for shoppers.

The UN's Universal Postal Union, which promotes cooperation between postal services of its 192 member countries, said the changes "will entail considerable operational changes for postal operators around the world."
