22 CFR §121.1 Category XIII
USML Category XIII: Auxiliary Military Equipment
USML Category XIII is a broad catch-all for military equipment not captured by more specific categories — including military parachutes, pressure suits, underwater diving systems for military use, demolition equipment, and specialized equipment for nuclear weapons deployment. The category also covers self-contained underwater breathing apparatus (SCUBA) and other systems designed specifically for military combat diving or EOD operations.

Coverage
What Category XIII covers
USML Category XIII is a broad catch-all for military equipment not captured by more specific categories — including military parachutes, pressure suits, underwater diving systems for military use, demolition equipment, and specialized equipment for nuclear weapons deployment. The category also covers self-contained underwater breathing apparatus (SCUBA) and other systems designed specifically for military combat diving or EOD operations.
Common controlled items
- Military free-fall parachutes and ram-air deployment systems
- High-altitude pressure suits and G-suits for military aircrew
- Military combat diving equipment and rebreather systems
- Explosive ordnance disposal (EOD) robots and disruptor systems
- Nuclear weapon detonation components and arming/firing systems
- Military-specification demolition charges and shaped charges
- Inflatable military boats and combat swimmer delivery systems
EAR / ECCN
EAR overlap
Commercial parachutes and diving equipment are generally EAR-controlled or subject to minimal export controls. Items in Category XIII become ITAR-controlled when their performance specifications, design characteristics, or integration points are specifically tied to military applications — particularly items that could contribute to nuclear weapons delivery or clandestine military operations.
Licensing
Typical license requirements
DSP-5 licenses required. Items with potential nuclear weapons applications (arming, fuzing, firing components) are subject to enhanced scrutiny and may require Department of Energy coordination for dual-use nuclear-related equipment.
