U.S. President Donald Trump substantially raised tariffs on steel and aluminum imports on Monday to a flat 25% "without exceptions or exemptions" in a move he hopes will aid the struggling industries in the United States but which also risks sparking a multi-front trade war.

Near the top of an official "fact sheet" distributed by the White House on Tuesday morning, the Trump administration makes clear its rationale for imposing new tariffs on steel and aluminum imports.

"The change in the current trade scheme for aluminium and steel would be detrimental to the productive fabric in aggregate terms," the lobby said in its note, adding that Spain's total cast iron and steel exports to the U.S. reached 944 million euros ($977 million) in 2023.
