Postal services worldwide, including Australia, Japan, and numerous European countries, are pausing shipments to the United States due to the impending end of the de minimis tariff exemption. This regulation change is expected to significantly impact small businesses and online shoppers, as it eliminates duty-free shipping for low-cost parcels. Carriers like DHL and Royal Mail have already halted U.S. deliveries, citing confusion over new customs duties. As a result, many companies are scrambling to adapt to the new landscape, and consumers are advised to prepare for potential additional charges and shipping delays as international mail services grapple with these new restrictions.
