U.S. launches national security probe into semiconductor imports, eyes tariffs

According to a document to be published in the Federal Register on April 16, 2025, the US Department of Commerce has formally initiated an investigation into the national security implications of semiconductor and semiconductor manufacturing equipment (SME) imports. The investigation, led by the Department’s Bureau of Industry and Security (BIS), falls under Section 232 of the Trade Expansion Act of 1962, which empowers the Secretary of Commerce to assess whether specific imports pose a threat to national security.

Scope of investigation
The probe will evaluate a broad range of semiconductor-related products, including substrates, bare wafers, legacy and advanced-node chips, microelectronics, and SME components. It also includes downstream products that incorporate semiconductors that are vital to the electronics supply chain. The investigation aims to determine whether current levels of import reliance compromise domestic industry resilience, especially considering potential foreign export restrictions, unfair trade practices, and capacity limitations.

Public input requested
As part of the investigation, the Department is seeking public input. The deadline for submissions is 21 days after the publication date of the notice in the Federal Register.
