Trump Tariffs Squeeze South Korea Exports: Trade Tensions Threaten Economic Ties and Global Supply Chains

Listeners, welcome to “South Korea Tariff News and Tracker,” where we break down how Washington’s trade moves under Donald Trump are reshaping South Korea’s economy, industry, and its critical alliance with the United States. The big backdrop today is Trump’s sweeping tariff agenda. The Tax Policy Center’s Tariff Tracker reports that the administration’s package now includes a 10 percent minimum tariff on all imported goods, plus higher “reciprocal” tariffs aimed at roughly 60 countries. According to the Tariff Tracker, these measures are projected to raise about $247 billion in tariff revenue in 2026 alone, and about $2.3 trillion from 2026 through 2035, while cutting average real household income by roughly $2,900 in 2026. The tracker notes that product-specific tariffs on steel, aluminum, autos, and parts have been reinstated at up to 25 percent, and that earlier exemptions for allies such as South Korea have been removed, pulling Korean exports squarely back into the tariff net. Customs Info’s recent industry updates point to a new round of U.S. tariff schedule revisions, including “new 232 and reciprocal rates for Korea.” That is a reference to Section 232 national security tariffs and Trump’s “reciprocal tariffs” concept, under which countries with big surpluses with the U.S. can face sharply higher duties. For South Korean firms in steel, autos, batteries, and advanced components, these reciprocal rates mean higher costs and greater uncertainty when selling into the U.S. market. Seoul is responding at the diplomatic level. The Korea JoongAng Daily reports that Trade Minister Yeo Han-koo has departed for Washington to address U.S. concerns over Korea’s revised Network Act, which targets fabricated online information but has drawn criticism from the U.S. State Department as potentially discriminatory against American digital platforms. The Chosun Ilbo’s English edition adds that Yeo plans intensive outreach to the U.S. Trade Representative, key lawmakers, and industry groups. Behind the scenes, a postponed Korea–U.S. FTA Joint Committee meeting, originally intended to cover non-tariff barriers, is widely seen as a pressure point that could spill over into fresh tariff or retaliatory measures if the dispute escalates. Market watchers are also focused on the legal front. Bloomingbit reports that the U.S. Supreme Court could issue a ruling as early as mid-January on challenges to Trump’s reciprocal tariffs. A decision curbing presidential tariff powers could force a recalibration of some of these levies, including those hitting South Korean exporters. A decision upholding them would entrench the current high-tariff environment and confirm that allies like Korea remain exposed whenever their trade surplus with the U.S. becomes politically sensitive in Washington.
