SEMI Provides Statement on U.S. Supreme Court International Emergency Economic Powers Act (IEEPA) Tariff Ruling

338x255@2_blog post_6_24

On February 20, the U.S. Supreme Court ruled that the International Emergency Economic Powers Act (IEEPA) does not authorize the use of tariffs, invalidating certain tariffs imposed by the Trump Administration under the statute.

SEMI shared the following statement on the ruling: 

SEMI acknowledges today’s U.S. Supreme Court ruling regarding the use of tariffs under the International Emergency Economic Powers Act. As the implications of the decision become clearer, we welcome further guidance and remain committed to working with the U.S. government to strengthen semiconductor supply chains, support innovation, and expand domestic chip manufacturing.

Continued investment in U.S. manufacturing depends on stable, reliable access to the highly specialized equipment, materials, and components essential to semiconductor production. Driven by global demand, breakthrough innovation, and record levels of investment, the semiconductor industry is projected to reach a $1 trillion market this year. Clear, consistent, and predictable trade policy remains critical to providing manufacturers – particularly small- and medium-sized enterprises – the certainty necessary to sustain long term investment, scale production, and reinforce technological leadership in the United States.
