BIS is revising the Export Administration Regulations (EAR) in response to requests from the public to provide additional due diligence procedures regarding advanced computing integrated circuits (ICs). This rule will protect the national security of the United States and assist foundries and Outsourced Semiconductor Assembly and Test (OSATs) companies in complying with provisions of the EAR pertaining to advanced computing ICs in the supply chain. This rule also revises the EAR to make amendments and clarifications based on two interim final rules, Implementation of Additional Export Controls: Certain Advanced Computing Items; Supercomputer and Semiconductor End Use; Updates and Corrections,” published on April 4, 2024 and Refinements to Controls for Advanced Computing and Semiconductor Manufacturing Items,” published on December 5, 2024.
