U.S. Proposes 100% Tariff on Foreign-Made Chips

The global semiconductor supply chain is bracing for disruption as U.S. President Donald Trump announces plans to impose a 100% tariff on imported chips from countries that do not manufacture—or commit to manufacturing semiconductors on U.S. soil. 

The proposed policy builds on the momentum of the $52.7 billion CHIPS and Science Act, aimed at strengthening U.S. semiconductor self-sufficiency.  

Companies with proven plans or ongoing operations in the U.S. would be exempt. However, failure to comply or submitting false information may lead to retroactive penalties and possible legal action, according to officials familiar with the proposal. 

The announcement has triggered widespread industry discussion. Manufacturers, EMS providers, and OEMs are closely evaluating the implications on cost, logistics, and continuity of supply.  

Sectors highly dependent on specialized components—such as automotive, aerospace, and industrial electronics—are expected to be the most affected. 

Global Sourcing Strategies Under Pressure 

Analysts anticipate a significant reshaping of sourcing behavior, particularly for components historically sourced from Asia.

Leading chipmakers like TSMC, Samsung, and ASE may be encouraged to accelerate their U.S. facility investments—or reconsider their global operations strategy altogether. 

At the same time, U.S.-based semiconductor companies such as Intel, GlobalFoundries, and domestic OSATs may benefit from increased demand and greater policy-driven incentives. 

However, the policy may introduce new challenges for fabless chip companies that depend on offshore foundries, as well as overseas brokers and OEMs sourcing legacy or long-lead-time parts. These groups could see rising costs and potential sourcing delays.
