Introduction to the US-South Korea Trade Dispute
U.S. President Donald Trump announced on Monday that he would be increasing tariffs on imported autos, pharmaceuticals, and lumber from South Korea from 15% to 25%. This decision comes as a response to the delay in South Korea’s legislature approving a trade deal with the United States, which was reached last summer. According to Trump, the deal, which was reaffirmed during his visit to South Korea on October 29, 2025, has not been approved by the Korean Legislature, prompting the tariff hike.
As a result of the announcement, Hyundai Motor shares fell as much as 4.77% but later pared losses and were last down 0.81% in volatile trading. The South Korean-based company is the largest importer of new vehicles from that country into the United States. Additionally, the share price of Hyundai’s subsidiary Kia dropped nearly 3.5%, and the affiliated Hyundai Mobis was down 5%, according to Reuters.
Background on the Trade Deal
The trade deal, announced in July 2025, included a provision where the U.S. would impose blanket tariffs of 15% on imports from South Korea, 10 percentage points lower than the level Trump had threatened earlier that month. Trump also stated that South Korea had agreed to “give to the United States $350 Billion Dollars for Investments owned and controlled by the United States, and selected by myself, as President.” However, the deal has yet to be approved by the Korean Legislature, leading to the current tariff dispute.
It is worth noting that the U.S. imported $131.6 billion in goods from South Korea in 2024, according to the Office of the U.S. Trade Representative. South Korea is one of the biggest exporters of goods to the United States, making this trade dispute a significant issue for both countries. The U.S. Supreme Court has also heard arguments in a case challenging the legality of Trump’s unilaterally imposed tariffs, with justices expressing skepticism that he had the power to levy such duties without authorization of Congress.
Impact and Response
The news of the tariff hike has been met with concern from South Korea, with the presidential Blue House stating that the U.S government had not officially notified South Korea of the tariff hike. A meeting with related ministries is scheduled to discuss measures related to the increase. The increase in tariffs is likely to have a significant impact on the trade relationship between the two countries, and it remains to be seen how this dispute will be resolved.
