The US Department of Commerce, Bureau of Industry and Security (BIS), recently unveiled two updated interim final rules concerning semiconductor manufacturing equipment and advanced computing items. On the same day, BIS also introduced new designations to the Entity List, aligned with the national security focus on advanced integrated circuits, artificial intelligence, and related technologies. Together, these revisions further emphasize BIS’s management of the national security issues related to crucial technologies through a combination of restrictions, licensing, presumptions of denial, and transparency.
