As part of the probe, the Commerce Department will investigate the "feasibility of increasing domestic semiconductors capacity" in order to reduce reliance on imports and whether additional trade measures, including tariffs, are "necessary to protect national security."
The investigation encompasses a wide range of items, including chip components such as silicon wafers, chipmaking equipment, and "downstream products that contain semiconductors."
Semiconductors play a role in essentially every type of modern electronics, giving the investigation massive implications for Trump's global trade war as he seeks to boost U.S. manufacturing.
