Mexico halts mail to U.S. due to new customs rules confusion, impacting over 30 countries.

Mexico has temporarily halted postal shipments to the U.S. due to confusion over new customs rules and the end of the "de minimis" exemption, which allowed duty-free entry for packages under $800. This move follows similar actions by postal services in Europe and other countries awaiting clarification on the new tariffs. The suspension affects businesses and consumers, with over 30 countries limiting or stopping shipments to the U.S.
