South Korea's 15 Percent Tariff Rate Holds After Trump's Supreme Court Setback and New Global Tariff Order

The U.S. Supreme Court struck down President Donald Trump's sweeping reciprocal tariffs on Friday, invalidating the measures imposed under the International Emergency Economic Powers Act, according to Korea JoongAng Daily. Trump swiftly countered with a new 15 percent global tariff under Section 122 of the 1974 Trade Act, posting on Truth Social that it targets countries ripping off the U.S., as reported by the Korea Times. For South Korea, this means the prior deal reducing tariffs from 25 percent to 15 percent—secured last November in exchange for a $350 billion U.S. investment pledge—holds steady short-term, matching the new global rate. Korea Herald Global notes Seoul's presidential office reaffirmed the investment plan during emergency meetings chaired by National Security Adviser Wi Sung-lac and Policy Chief Kim Yong-beom, dismissing renegotiation calls despite some uncertainty. Trump had threatened to hike Korea's rate back to 25 percent in January over delays in passing special investment legislation, per Chosun Biz. Sector-specific tariffs under Section 232 remain untouched, hitting key exports like automobiles at 25 percent (with Korea's modified rate effective November 2025), steel, and semiconductors, as detailed in the Trade Compliance Resource Hub's Trump 2.0 tariff tracker. Korean officials, including Industry Minister Kim Jung-kwan, held urgent sessions with embassies and private sector leaders, stressing the tariff agreement's core conditions persist. The National Assembly's special committee advances the investment bill for a March 5 plenary vote, linking to broader alliance ties like shipbuilding and nuclear submarines, SEDaily reports. Experts warn of looming sector-specific escalations, potentially complicating Korea's 2.0 percent growth forecast amid strong exports. Korea Institute for Industrial Economics & Trade's Kim Kwang-seok highlighted adaptation burdens for firms already adjusting. Seoul treads cautiously, monitoring U.S. moves without rushing friction, as a former trade official advised in Korea JoongAng Daily.
