NMFC 146250 - Cannon/Howitzer/Mortar Guns | Class N/A

To find the correct freight class for your shipment:

1. Confirm the unit is empty and inert—no propellant, primers, or explosive components—and note “demilitarized/display only” on the BOL with NMFC 146250.
2. Engineer packaging for weight and balance: muzzle caps, barrel cribbing, and carriage tie-downs. Block and brace on a steel-reinforced skid or ISPM‑15 crate; mark center of gravity and lift points.
3. Select the right equipment by dimensions and access: most pieces move best on flatbed/step-deck with chains and edge protection; LTL acceptance is rare and requires terminal pre-approval.
4. Plan compliance and handling upfront: obtain any ATF/ITAR/EAR approvals as applicable, provide photos and exact specs to carriers, and schedule cranes or heavy forklifts for pickup and delivery.

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

• Reduce reclass and rebills by citing NMFC 146250 and stating “empty/inert,” avoiding hazmat surcharges when no explosive materials are present.
• Accelerate carrier approvals with clear documentation, measurements, and packaging plans, cutting dwell time and rescheduling fees.
• Minimize damage and claims through purpose-built cribbing and crating that control barrel movement and protect trunnions and mounts.
• Optimize cost by matching mode to the asset—step-deck vs. RGN vs. specialized flatbed—so rates reflect actual handling needs, not guesswork.
