What are the key details of President Trump's new tariff policy on steel and aluminum imports?

President Donald Trump announced a comprehensive 25% tariff on all steel and aluminum imports as part of his strategy to reshape international trade relations. The tariffs are implemented universally across all countries without exemption, responding to what Trump describes as domestic producers being "pummeled by both friend and foe alike." This bold trade policy move signals a significant shift toward protectionism and could potentially escalate international trade tensions while impacting global market stability and U.S. foreign trading relationships.
