- President Trump announced an increase in tariffs from 15% to 25% on South Korean imports, specifically targeting autos, lumber, and pharmaceuticals.
- The move comes after the South Korean legislature failed to ratify the “Historic Trade Agreement” brokered between Trump and President Lee Jae Myung in July 2025.
- The administration had previously lowered these duties to 15% in anticipation of the deal, but the latest move restores the higher 25% rate.
President Donald Trump announced on Monday a significant escalation in trade tensions, raising tariffs on key South Korean imports to 25%. The decision, revealed via social media, serves as a retaliatory measure against Seoul’s National Assembly for its delay in enacting a bilateral trade framework that was initially agreed upon in July 2025 and reaffirmed during a presidential visit to Korea in October.
The tariff hike marks a reversal of previous rollbacks. Under the proposed trade pact, Washington had agreed to cap import duties at 15% on goods including vehicles and car parts. However, Trump cited the lack of legislative action in Seoul as a breach of the agreement’s spirit. “Because the Korean Legislature hasn’t enacted our Historic Trade Agreement, which is their prerogative, I am hereby increasing South Korean TARIFFS on Autos, Lumber, Pharma, and all other Reciprocal TARIFFS, from 15% to 25%,” Trump stated.
The timing of the announcement follows reports that South Korea’s planned $350 billion investment in strategic U.S. sectors—a cornerstone of the trade deal—faced delays. South Korean officials recently suggested the investment might not commence in the first half of 2026, citing the weakness of the won and concerns over massive currency outflows. The won has recently traded at levels not seen since the global financial crisis, complicating Seoul’s ability to fulfill the capital commitments demanded by Washington.
Industry analysts note that the automotive and pharmaceutical sectors will be most heavily impacted by the 10 percentage point increase. South Korea remains a top-ten trading partner for the U.S., with annual imports totaling nearly $150 billion. The 25% rate places South Korean automakers on a different footing compared to competitors who may still benefit from existing trade exceptions or lower baseline duties.
The legal basis for the tariffs remains under scrutiny, as the U.S. Supreme Court is expected to rule soon on the administration’s use of the International Emergency Economic Powers Act (IEEPA) to bypass Congress for such trade actions. Despite the potential for legal challenges, the administration has signaled that it will continue to use tariffs as a primary tool to enforce reciprocal trade terms with allies and adversaries alike.
“Our Trade Deals are very important to America,” Trump added. “In each of these Deals, we have acted swiftly to reduce our TARIFFS in line with the Transaction agreed to. We, of course, expect our Trading Partners to do the same.”
