The presidential office on the 21st said regarding the U.S. Supreme Court's ruling that the reciprocal tariff introduced by the Trump administration was unlawful, "We plan to comprehensively review the details of the U.S. Supreme Court ruling and the U.S. government's position and proceed in the direction that best serves the national interest."
Earlier, U.S. President Donald Trump on Apr. 2 last year declared a national emergency, arguing that America's chronic, large trade deficit and the illegal inflow of drugs (fentanyl) across the border were a "national security threat." He then imposed a reciprocal tariff on America's trading partners based on the International Emergency Economic Powers Act.
Under the Korea-U.S. Free Trade Agreement (FTA), most items had their tariffs eliminated, effectively facing a 0% tariff. The Trump administration announced it would impose a 25% reciprocal tariff on Korea, and the Korean government, after negotiations with the United States, lowered the reciprocal tariff to 15% in October last year. It was on the condition of investing a total of $350 billion in the United States, including $150 billion in the shipbuilding sector.
On the 20th (local time), the U.S. Supreme Court finalized the lower court's ruling that the reciprocal tariff measure was unlawful because the president has no authority to impose tariffs under the International Emergency Economic Powers Act. However, the Trump administration says it will maintain the reciprocal tariff policy through other means.
