NMFC 131740 – Tractor Axle Housings, Iron | Class 55

To find the correct freight class for your shipment:

1. Enter NMFC 131740 and Class 55 on the BOL using the description “Tractor Axle Housings, iron, unfinished” to prevent reclass or inspection delays.
2. Secure each housing to a pallet with bolts through existing holes or custom clamps; add wood blocking at the flanges and band tightly. Do not rely on stretch wrap alone.
3. Protect raw iron from rust and chipping: use edge guards, VCI paper, and foam on sharp cast ribs. Mark lift points and keep the centerline supported.
4. Plan handling like heavy machinery: forklift only under the skid, or lift with a spreader bar and slings. Non-hazardous item; no density calculation required.

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

• Lower landed cost with a fixed Class 55 designation that often prices below many auto parts classes, improving LTL rate competitiveness.
• Accurate NMFC coding (131740) reduces carrier disputes, reclassification fees, and rebills for axle casting shipments.
• Damage mitigation from proper blocking and corrosion control keeps cores usable for machining, cutting scrap loss and schedule interruptions.
• Simplified quoting and routing—non-hazardous machinery group freight moves quickly across most carrier networks and is easy to consolidate.
