A significant change in U.S. tariff regulations has led to the end of the de minimis exemption for low-value packages, which previously allowed goods valued at $800 or less to enter the country duty-free. This has resulted in billions of packages from around the world now facing steep tariffs, raising concerns among U.S. shoppers and businesses. Companies in various countries, including Canada and Mexico, have suspended postal shipments to the U.S. due to the new tariffs, with reports of over 30 nations halting or restricting deliveries. As small businesses grapple with the potential impact on imports and rising costs, shoppers may find their online orders canceled or delayed, further complicating the e-commerce landscape amid a chaotic international shipping environment.
