Trade overview

South Korea is one of the United States' largest trading partners and a key ally in the Indo-Pacific region. The US-Korea Free Trade Agreement (KORUS FTA), in force since 2012 and updated in 2019, governs bilateral trade and has eliminated tariffs on the majority of goods exchanged between the two countries. Major US imports from South Korea include semiconductors, vehicles, machinery, and electronics, while the US exports aircraft, agricultural products, and industrial equipment to South Korea.
