A final rule issued by the Bureau of Industry and Security (BIS) on October 5, 2021 will place new controls on the export of certain biotech software designed for nucleic acid assemblers and synthesizers by establishing new Export Control Classification Numbers or “ECCN” to regulate the export. The BIS is the arm of the U.S. Department of Commerce responsible for the regulation and licensing of exports of commercial and so-called, “dual-use” technology.
