According to Internet reports, according to a Federal Register notice posted online on Monday, the U.S. Department of Commerce is conducting a national security investigation into imported semiconductor technology and related downstream products. The official document, which asked for public comment on the investigation, further confirmed that the chip and electronics supply chain would not be excluded from Trump's tariff plan, although he said on Friday that many of those products received "reciprocal tariff exemptions." The Commerce Department will investigate the "feasibility of increasing domestic semiconductor production capacity" to reduce reliance on imports and whether additional trade measures, including tariffs, are "necessary to protect national security." The scope of the investigation is wide, including chip components such as silicon wafers, chip manufacturing equipment, and "downstream products containing semiconductors". (Jin Shi)
