U.S. Opens 301 Probe Into South Korea Over Global Overcapacity

The United States has opened Section 301 investigations into 16 countries, including South Korea, as part of a broad push to address what it calls structural overcapacity in global manufacturing. The probe focuses on electronics equipment, automobiles and parts, machinery, steel, and ships, and aims to determine tariff measures before a pending 10% global tariff deadline in late July.

South Korea’s government says it will engage actively with Washington to ensure its treatment is fair and not worse than that given to major trading partners, preserving the benefits already secured under the Korea–U.S. trade framework. Blue House officials stressed the importance of maintaining a level playing field in these negotiations.

In Seoul, Han Yu-gu, head of the Trade Negotiations Bureau at the Ministry of Trade, Industry and Energy, described the administration’s objective as restoring tariff levels to where they stood prior to a Supreme Court ruling over reciprocal tariffs. The government signaled its readiness to work with the United States to avoid a skewed outcome in favor of other economies.

The USTR said the public comment period runs from February 17 to March 15, with a public hearing scheduled for May 5. The process is designed to wrap up decisions in time to influence tariff actions before the July deadline, potentially changing how Korean and other foreign producers operate in U.S. markets.

Separately, the U.S. plans a parallel 301 investigation into whether products from about 60 countries are produced with forced labor. If findings indicate risk, this could lead to additional restrictions on imports from those nations, including Korea, depending on the evaluation of supplier practices.

The scope of digital- and regulation-related reviews is also expanding. The USTR has signaled that topics such as digital services taxes, drug pricing, access to rice and seafood markets, and environmental concerns like ocean pollution could become part of the broader 301 examination, expanding beyond traditional tariff issues.

Industry observers note that the current push is part of a broader U.S. effort to recalibrate global trade rules and enforce compliance with labor and regulatory standards. Some experts suggest that even if Korea remains a relatively large recipient of U.S. imports, the administration’s stance on fair treatment and competitive parity will shape how Korean companies invest and operate in the United States.

For the United States, the cross-border implications are concrete. Any new tariffs or regulatory barriers could affect the American manufacturing and tech supply chains increasingly reliant on Korean electronics, automotive components, and shipbuilding inputs. The outcome will also influence ongoing U.S.–Korea cooperation on defense, infrastructure, and the broader framework of the Korea–U.S. Free Trade Agreement. Beyond economics, the moves signal how U.S. policy seeks to address global supply-chain resilience, labor standards, and regulatory alignment in a shifting geopolitical economy.
