Section 1758 of the Export Control Reform Act of 2018 (ECRA), as codified under 50 U.S.C. 4817, authorizes BIS to establish appropriate controls on the export, reexport or transfer (in-country) of emerging and foundational technologies.  Pursuant to ECRA, BIS has identified Brain Computer Interface (BCI) technology as part of a representative list of technology categories concerning which BIS, through an interagency process, seeks public comment to determine whether this technology represents an emerging technology that is important to U.S. national security and for which effective controls can be implemented.  Specifically, BIS is seeking comments concerning whether this technology could provide the United States, or any of its adversaries, with a qualitative military or intelligence advantage. In addition, BIS is seeking public comments on how to ensure that the scope of any controls that may be imposed on this technology in the future would be effective and appropriate (with respect to their potential impact on legitimate commercial or scientific applications).
