US–Taiwan Pact Trades 5+ New TSMC Arizona Fabs for 15% Tariff Rate

Washington and Taipei have agreed in principle to cut the Trump-era 20 % reciprocal tariff to 15 %, provided TSMC roughly doubles its U.S. footprint by adding at least five more semiconductor plants in Arizona.

Duties on Taiwanese imports will drop from 20 % to 15 % once the agreement clears legal review, matching Japan and South Korea’s 2025 deals.
TSMC has pledged a minimum of five additional Arizona fabs beyond the six already announced, expanding its committed U.S. capacity to at least eleven plants.
On 7 Jan 2026 TSMC bought 3.64 million m² of land in Arizona for US$197 million to accommodate the new facilities.

Great-power trade deals have coerced foreign firms to build on U.S. soil before—think the 1981 Voluntary Export Restraints that pushed Honda to open its Ohio auto plant in 1982—but never with an asset as strategically central as leading-edge logic chips. The pact underscores two accelerating megatrends: supply-chain securitization of “chokepoint” technologies and the extrusion of high-value manufacturing out of East Asia amid Sino-American rivalry and Section 232 tariff threats. If executed, dual hubs in Taiwan and Arizona could dull Taipei’s so-called “silicon shield,” altering the deterrence calculus much as the 1957 Sputnik launch rewired U.S. science policy. On a century scale the move is another brick in a slow de-globalization wall: national security is overtaking cost efficiency, reshaping where the world’s most sophisticated factories sit—and with them, geopolitical leverage.
