Overview
- The White House said the 25% rate on selected South Korean imports takes effect immediately.
- Trump cited South Korea’s National Assembly for not ratifying a 2025 framework that had reduced U.S. duties to 15%.
- The increase targets autos, pharmaceuticals and lumber, with “all other reciprocal tariffs” raised to the same rate.
- The move reverses prior concessions and raises trade and geopolitical risk for U.S.–Korea supply chains, especially in autos.
- The tariff policy faces a pending U.S. Supreme Court ruling on presidential authority, and Seoul offered no immediate comment.
