The de minimis exemption, allowing duty-free import of low-value shipments under $800, has been terminated by President Trump's executive order, impacting global supply chains and increasing costs for consumers and businesses alike. This abrupt change has created operational challenges for retailers, particularly small companies reliant on e-commerce, with potential price hikes leading to an estimated $10.9 billion cost to U.S. consumers. The measure aims to enhance scrutiny on imports and combat issues like illegal goods entering the country.
