NMFC 146190 - Gun Carriages or Mounts, NOI | Class 100

To find the correct freight class for your shipment:

1. Secure the mount or carriage to a steel or hardwood skid; bolt through base plates and add blocking to stop roll, pitch, and yaw during LTL handling.
2. Lock all moving parts (traverse, elevation, pintles) with transport pins or clamps and pad exposed trunnions; cap threads and cover bearings to prevent impact and dust.
3. Use a crated enclosure or rigid frame with corner protection for pedestal or tripod mounts that have a high center of gravity; strap with steel or polyester banding in at least two directions.
4. Mark paperwork and the crate clearly: “Inert Mount Only – No Firearm, No Ammunition.” List NMFC 146190, Class 100 on the BOL and verify carrier acceptance for ordnance support equipment.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Predictable costing: fixed Class 100 removes density disputes and reduces reclass or inspection fees.
• Fewer damages and claims when mounts are bolted to bases and fully braced, cutting downtime for armories or test ranges.
• Faster tendering and pickup by clearly labeling non-hazardous, inert hardware and including the NMFC number on shipping docs.
• Better budgeting for defense contractors and integrators by standardizing pack methods (crated or skidded) across projects and lanes.
