NMFC 131780 - Tractor Axles | Class N/A

To find the correct freight class for your shipment:

1. Describe the axle precisely on the BOL: drive or steer, bare housing vs full assembly (hubs/brakes), and metal type; note capped ends (e.g., “tractor axle housing, forged steel, capped”).
2. Prevent rolling and point-load damage by seating the tube in V-blocks or saddles inside a crate, chocking both sides, and banding tightly to a 48x96 pallet with edge protectors.
3. Protect machined surfaces and seals: cap splines and flanges, plug vent ports, add VCI corrosion wrap, and keep total skid height under 48 in to avoid cubic minimum charges.
4. For multi-axle shipments, separate layers with 4x4 dunnage and anti-slip mats, stagger hub flanges so forklift tines clear, and label clamp points to prevent tine punctures.

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

• Lower damage claims by shielding splines, flanges, and seals—fewer reworks and faster dealer or farm turnaround.
• Clear descriptions referencing NMFC 131780 reduce reclass risk and surprise re-rate fees even with Class N/A.
• Optimized, low-profile skids improve trailer utilization and help avoid linear-foot or cubic minimum surcharges.
• Non-hazardous status trims paperwork and avoids hazmat-related accessorials for smoother carrier approvals.
