On January 15, 2025, the U.S. Department of Commerce Bureau of Industry and Security (BIS) published in the Federal Register updated export controls on advanced computing items (including advanced integrated circuits (ICs) and related equipment, software, and technology) and, for the first time, controls on artificial intelligence (AI) model weights under the Export Administration Regulations (EAR). These new regulations were published as an interim final rule and took effect on January 13, 2025, although compliance is not required until May 15, 2025. BIS also published in the Federal Register a smaller companion rule on January 16, 2025, that expands licensing requirements on foundries and packaging companies seeking to export advanced computing equipment and requires compliance by January 31, 2025.
