TAIPEI (Taiwan News) — A US Supreme Court ruling on tariffs is expected to have limited impact on Taiwan’s semiconductor exports, the New York Times reported Friday.

Taiwan’s main exports to the US, including chips and electronic components, fall under tariff exemption provisions, per CNA. As a result, only a small share of Taiwan’s shipments — such as plastics, textiles, and some agricultural goods — would be affected.

The decision has disrupted the Trump administration’s rollout of global tariffs and forced major trading partners to reassess their exposure. US President Donald Trump has also announced an additional 10% tariff increase, adding to uncertainty for global businesses.

In 2024, the US overtook China as Taiwan’s largest export market. When tariffs were announced in April, chips and related components were excluded under special provisions, shielding the bulk of Taiwan’s trade.

Trump said at a recent press conference that many existing trade agreements remain in place, though some could lapse and be replaced by new tariffs. Companies do not expect refunds on duties already paid and are watching how the court’s ruling will be enforced.

Tariff rates and categories now vary widely depending on the country and the legal basis used, per CNA. After months of negotiations, Washington has imposed different base rates, sector-specific levies, and national security tariffs across trading partners.

For China, the court ruling effectively cancels certain stacked tariffs, including a 10% general tariff and a separate 10% fentanyl-related duty. However, additional measures such as Section 301 tariffs and national security levies on steel, aluminum, and strategic goods remain in place.

Canada and Mexico are expected to see little change. Most Canadian exports to the US remain tariff-free under the United States-Mexico-Canada Agreement, while special-category tariffs on steel and aluminum are not tied to the Supreme Court decision, and Mexico faces similar sector-specific duties.

Japan and South Korea are under pressure over delays in fulfilling investment commitments made in trade talks with Washington. Trump has signaled he could raise tariffs again if he views those pledges as unmet.
