Building a U.S. Supply Chain: What Japanese, Korean and Taiwanese Companies Should Model First

Companies in Japan, South Korea, Taiwan and Singapore have announced major U.S. investments in semiconductors, batteries, autos and electronics. Many more mid-sized suppliers are now asking whether they need to follow their customers to America. The right answer depends on careful economics, not headlines.

Where U.S. trade policy stands

U.S. trade policy changed several times in 2026. In February, the Supreme Court ruled that tariffs imposed under the International Emergency Economic Powers Act (IEEPA) were not authorized. A temporary Section 122 surcharge followed, and when it expired in July, the administration moved to new Section 301 actions. Sector tariffs under Section 232, including on steel, aluminum and autos, have continued throughout. Rates and coverage are still shifting, so any plan should be checked against the current schedule before you commit capital.

What to model first

  • Customer requirements. Are your U.S. customers asking for local content or shorter lead times?
  • Landed cost by route. Compare direct shipment, third-country assembly and U.S. production.
  • Labor and operating costs. U.S. wages are higher, but automation, energy and logistics costs can offset part of the gap.
  • Incentives and grants. State and local programs can affect site choice, and many require an economic impact or benefit-cost analysis.
  • Policy risk. Build scenarios rather than assuming today’s tariff rates will hold.
