State Department removes certain uncrewed underwater vehicles from the U.S. Munitions List and solicits comments on refined UUV controls

Executive Summary

The Department of State published a final rule on September 18, 2026 amending ITAR Category XX(a) to remove specified uncrewed underwater vehicles from the U.S. Munitions List. The rule also opens a comment period to further refine UUV controls and identify enhancements to the license exemption for certain UUV-related activities.

Bottom Line

The rule removes specified UUVs from the U.S. Munitions List, ending ITAR jurisdiction over those items and placing them under the Export Administration Regulations. Every exporter, manufacturer, and technology developer whose products or technical data fall within the removed Category XX(a) entries carries an immediate reclassification obligation: existing ITAR registrations, licenses, and agreements referencing those entries no longer govern the affected items. The concurrent comment solicitation keeps the broader UUV control architecture open to further revision, meaning the current delineation between ITAR and EAR coverage for UUVs is not yet final.

Key Regulatory Signals

• USML Removal Shifts Jurisdiction for Affected UUVs: UUVs removed from Category XX(a) transition from State Department export licensing under ITAR to Commerce Department jurisdiction under the Export Administration Regulations. Exporters, manufacturers, and technology developers holding ITAR registrations for these items must reclassify their products and determine whether a new Commerce Control List classification applies before any export or re-export.
• Conforming Changes Affect Related Controls: The rule makes conforming amendments to controls related to the removed UUV entries. Exporters and defense contractors whose authorizations, technical-assistance agreements, or manufacturing-license agreements reference the affected Category XX(a) entries must review those instruments for continued accuracy and compliance.
• License Exemption Enhancements Under Review: The Department solicits comment specifically on possible enhancements to the existing license exemption for certain UUV-related activities. Companies currently relying on that exemption for allied-nation transfers, cooperative development, or maintenance activities have a direct stake in the comment record.
• Comment Period Opens a Structural Refinement Process: The simultaneous request for comments signals that the September 18 rule is not the terminal action on UUV controls. The Department is actively seeking industry input to further delineate which UUV capabilities remain on the USML, which migrate to Commerce, and how exemptions should be scoped.

Regulatory Delta

- This action continues the USML Category-by-Category review initiated under the Export Control Reform Act of 2018, which has progressively moved dual-use defense items from ITAR to EAR jurisdiction. UUV controls in Category XX had not previously been subject to a removal action of this scope.

- The structural departure here is the pairing of a final removal rule with a simultaneous request for further comment. This signals that the Department views current Category XX(a) coverage as unsettled and subject to additional revision.

- The Commerce Department's Bureau of Industry and Security will receive jurisdiction over the removed UUV items. Its Export Administration Regulations classification decisions now govern affected exporters.

Materiality Classification

HIGH — This is a final rule altering ITAR jurisdiction over a defined class of defense articles, requiring immediate reclassification, registration review, and agreement audits by all exporters, manufacturers, and technology developers whose products or technical data fall within the amended Category XX(a) entries.

Intelligence Outlook

Monitor the Department of State Directorate of Defense Trade Controls and the Commerce Department Bureau of Industry and Security for the corresponding Export Administration Regulations classification determinations for the removed UUV entries, and for any subsequent final rule following the comment period on this rulemaking.
