In 2025, President Trump implemented sweeping tariffs, significantly impacting U.S. trade. A 10% baseline tariff on all imports began April 5, with higher reciprocal tariffs for countries with large trade deficits, effective April 9. Tariffs on Canada, Mexico (25%), and China (10%) started February 4, citing fentanyl and immigration concerns. Steel and aluminum tariffs rose to 50% on June 4. The U.S.-China trade deal reduced tariffs to 30% and 10%, respectively, by May 14. Legal challenges deemed some tariffs unconstitutional, but they remain pending appeal. Tariffs aim to boost U.S. manufacturing but risk higher consumer prices and global trade tensions.
