The Bureau of Industry and Security (BIS) maintains, as part of its Export Administration Regulations (EAR), the Commerce Control List (CCL), which identifies certain items subject to Department of Commerce jurisdiction.  This final rule revises the CCL, as well as corresponding parts of the EAR, to implement certain changes made to the Wassenaar Arrangement List of Dual-Use Goods and Technologies (WA List) maintained and agreed to by governments participating in the Wassenaar Arrangement on Export Controls for Conventional Arms and Dual-Use Goods and Technologies (Wassenaar Arrangement, or WA) at the December 2021 WA Plenary meeting.  The Wassenaar Arrangement advocates implementation of effective export controls on strategic items with the objective of improving regional and international security and stability.  This final rule implements multilateral controls on recently developed or developing technologies, which were identified by the WA December 2021 WA Plenary Meeting in a manner contemplated by the Export Control Reform Act of 2018 (ECRA) to identify emerging technologies that are essential to U.S. national security.  This rule harmonizes the CCL with the WA December 2021 Plenary Meeting decisions that pertain to these technologies.  The inclusion of the technologies in this final rule is consistent with the requirements of ECRA and the decision of the WA to add such technologies to its control lists, thereby making exports of such technologies subject to multilateral control.  As these technologies are recently developed or developing technologies that are essential to the national security of the United States, early implementation of the applicable WA December 2021 Plenary agreements is warranted.  The remaining WA 2021 Plenary agreements will be implemented in a separate rule.
