This Interim Final Rule addresses comments received in response to only the part of the October 7 IFR that controls semiconductor manufacturing equipment (SME) and amends the EAR to more effectively implement SME controls.  In particular, this SME IFR removes Export Control Classification Number (ECCN) 3B090 and adds both new SME and revised former 3A090 SME controls to ECCNs 3B001 and 3B002, makes conforming revisions to associated software and technology ECCNs, and makes other revisions to the EAR to reflect the removal of ECCN 3B090. This rule also includes other revisions, including revisions to the U.S. persons activities controls and supercomputer and semiconductor manufacturing end use controls to better achieve the objectives of the October 7 IFR and improve clarity; addition of two new defined terms to the EAR for extreme ultraviolet (EUV) and advanced-node integrated circuit; and removal of a Temporary General License (TGL) that is no longer valid and addition of two new TGLs to address additional supply chain issues that were identified after the October 7 IFR. This IFR is published concurrently with a second BIS IFR, Implementation of Additional Export Controls: Certain Advanced Computing Items; Supercomputer and Semiconductor End Use; Updates to the Controls and Corrections, which addresses public comments received in response to other portions of the October 7 IFR. Together, these IFRs clarify the October 7 IFR controls and more specifically achieve BIS’s targeted objective of restricting China’s ability to modernize its military capabilities in ways that threaten the national security interests of the United States and its allies and to violate human rights.
