NMFC 146870 - Torpedo Launching Tubes | Class 100

To find the correct freight class for your shipment:

1. Rate shipments under NMFC 146870 at Class 100; use this single class for quoting and tendering regardless of density or dimensions.
2. Package cylinders in rigid cradles or foam-lined V‑blocks on 4‑way skids, cap both ends, apply moisture barrier wrap, and block/strap to prevent rolling.
3. Book carriers experienced with overlength and cylindrical freight; note lift points, center of gravity, and whether side-load with forklifts or overhead crane is required.
4. Declare the items as inert hardware on paperwork and include export-control status if applicable; attach packing photos and serials for defense program traceability.

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

• Fixed Class 100 simplifies pricing across lanes, reducing reclass disputes and unexpected adjustments.
• Purpose-built cradling and blocking minimize transit damage, lowering claims and avoiding costly schedule slips for shipyards or defense integrators.
• Clear overlength and handling instructions up front cut accessorials and help select the right LTL or specialized carrier the first time.
• Consistent NMFC usage supports audit-ready documentation for defense contracts and speeds approvals with primes and government customers.
