Mexico has halted small package shipments to the United States as Washington prepares to end a tariff exemption for goods worth under $800. The “de minimis” rule, in place since 2016, allowed duty-free entry but will expire Friday under President Donald Trump’s trade agenda, Al Jazeera reported.

Mexico said it is awaiting clarity on how the new tariffs will be applied, joining several European countries that have taken similar steps. The White House plans to impose tariffs of 10 to 40 percent, either based on package value or a flat rate of $80–$200 per item. Mexico is negotiating its rate while pledging tougher action against drug cartels and higher tariffs on Chinese imports to secure a deal.
