Summary
President Donald Trump has announced an increase in tariffs on imported steel and aluminum from 25% to 50%, effective June 4, 2025. This move aims to bolster U.S. industries by countering low-priced imports that threaten national security and the competitiveness of domestic producers. While this decision may strengthen American manufacturers, it could also lead to higher costs for industries reliant on these materials and potentially strain trade relations, particularly with countries affected by the tariffs, although the United Kingdom is exempt due to a recent economic agreement.
