Trump Signs Executive Order Boosting Tariffs on Steel and Aluminum to 50%

On Tuesday, June 3, 2025, President Trump signed an executive order increasing tariffs on imported steel and aluminum from 25% to 50%. These metals are considered strategically important industries that the White House intends to protect. The new tariffs took effect at 00:01 local time (07:01 Greek time). In the official statement, Trump stated that the tariff increase was necessary to regulate imports and ensure they do not jeopardize national security. According to the president, the increased tariffs will effectively counter foreign nations exporting surplus production at low prices to undermine U.S. metal industries. Despite previous tariffs providing some support, they were insufficient for the industries’ sustainable growth and defense needs. Canada, the largest supplier of these products to the U.S., has already challenged the initial tariffs through the World Trade Organization, arguing the measures violate U.S. international trade obligations.
