Taiwan sees limited chip impact from new US polysilicon tariff

The U.S. imposition of a 15% tariff on polysilicon from all countries signals a strategic move to control critical materials, with limited immediate impact on Taiwan's semiconductor supply chain. While firms with U.S. investments are exempted, Taiwanese manufacturers reliant on American equipment face potential supply chain disruptions. This policy reflects a broader trend toward supply chain reshoring, pushing companies to seek alternative sourcing strategies. In the medium term, rising material costs may constrain capital expenditure in advanced nodes, especially as global chip production scales up. Competitors like South Korea and Japan may leverage this shift to strengthen their own material capabilities. The long-term effect could see a bifurcated global semiconductor ecosystem, with increased regionalization and cost pressures on downstream fabrication. Taiwan, China's semiconductor players are likely to accelerate integration with mainland suppliers to mitigate future regulatory risks.
