The end of an exemption on tariff duties for low-value packages coming into the United States is causing multiple international postal services to pause shipping as they await more clarity on the rule.

The exemption, known as the " de minimis" exemption, allows packages worth less than $800 to come into the U.S. duty free. A total of 1.36 billion packages were sent in 2024 under this exemption, for goods worth $64.6 billion, according to data from the U.S. Customs and Border Patrol Agency.
