On September 4, 2025 (local time), U.S. President Trump declared that significant tariffs would be slapped on imported goods from companies that opt not to shift their semiconductor manufacturing operations to the United States. He emphasized that the tariff rates would be “hefty, yet not over the top.” Trump also noted that companies either already investing in the U.S. or with firm plans to construct factories there might be spared from these tariffs. Earlier, TSMC, Samsung, and SK Hynix had all unveiled their intentions to build factories in the U.S. Trump's repeated reliance on tariffs as a means of exerting pressure has heightened global trade tensions and caused unease in financial markets, thereby amplifying the uncertainty faced by global manufacturers.
