On that date, 80 percent of U.S. exports to South Korea of consumer and industrial products immediately became duty-free. Since 2011, U.S. exports of both merchandise goods and services to the Republic of Korea (ROK) have increased by 19 percent to reach a record $73.4 billion in 2017.

Importance of Korea to Every Congressional District

By 2017, nearly 95 percent of U.S. exports to Korea became duty-free. For the first three quarters of 2018, total U.S. exports to South Korea have increased even further by 10 percent to reach nearly $60 billion, primarily driven by a 166 percent or $3.1 billion increase in oil and gas sales from the U.S. to the ROK. Full implementation of the KORUS FTA will occur on March 15, 2022, when almost all remaining tariffs will be eliminated. In 2018, the U.S. and South Korea signed additional modifications to KORUS primarily focused on the motor vehicle and pharmaceutical trade, along with streamlining customs procedures, with a goal to positively affect the U.S. economy. These changes went into effect on January 1, 2019.
