On Friday, September 18, 2026, the U.S. Department of State issued two rules amending the International Traffic in Arms Regulations (ITAR). The first, an interim final rule effective October 19, narrows U.S. Munitions List (USML) Category XX(a) controls on certain uncrewed underwater vehicles. The second, a final rule effective immediately, clarifies policy-of-denial provisions, updates country policies for Ethiopia and Somalia, and adds Saudi Arabia and Peru to the list of major non-NATO allies.

The interim final rule removes certain uncrewed underwater vehicles (UUVs) from the ITAR and makes conforming changes to related controls. The Department is also soliciting comments on further refinements to ITAR controls on UUVs and possible enhancements to related license exemptions. Comments are due on October 19, 2026.
