The Trump administration is evaluating the national security implications of imports related to personal protective and medical equipment due to a Section 232 investigation initiated by the Commerce Department on September 2. This review includes a range of products from surgical masks to pacemakers, assessing U.S. demand, domestic manufacturing capacity, and the effects of foreign trade practices. The investigation may lead to tariffs or quotas to safeguard national security and adds to ongoing scrutiny of several sectors, including semiconductors and pharmaceuticals, which have faced tariff threats.
