NMFC 168140 - Steel Wheel Tires for Railcars | Class 50

To find the correct freight class for your shipment:

1. Package as solid steel rings on blocked pallets or in steel racks; band through the bore with edge protectors to stop rolling and abrasion.
2. List “Steel wheel tires” on the BOL with NMFC 168140 and Class 50; include ring count, diameter, and total weight for accurate rating and handling.
3. Distribute weight low and centered; usually 2–4 rings per skid, limited height, anti-slip mats, and chocks to prevent lateral movement in transit.
4. Guard against moisture and staining: light oil or VCI wrap, plus stretch wrap over labels; avoid loose singles—bundle or crate for forklift-safe handling.

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

• Class 50 yields favorable base rates for dense steel, cutting LTL spend on routine shipments to wheel shops and MRO facilities.
• Simple, fixed classification reduces reclass exposure and billing disputes—no density calculations or dimensional qualifiers to trigger surprises.
• Rugged commodity tolerates tight consolidation (multiple rings per skid), improving cost per unit while maintaining claim resilience.
• Clear NMFC mapping streamlines procurement and ERP item masters, accelerating quote-to-booking cycles and carrier compliance.
