NMFC 166710 - Car Floors or Sills, Steel | Class 50

To find the correct freight class for your shipment:

1. Verify the parts are steel railcar floors or sills, then list part numbers and drawings on paperwork and mark NMFC 166710, Class 50 on the BOL.
2. Bundle long steel members with banding and edge guards on hardwood skids; block and brace to stop rolling or sliding, and mark lift points and center of gravity.
3. Limit rust and scuffs: use VCI wrap or oil paper for bare steel, cap sharp ends, and keep bundles within pallet footprints to avoid overhang fees.
4. Quote accurately: note any pieces over 96 inches or heavy lifts, choose carriers that accept long freight, and schedule dock times for cranes or spreader bars.

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

• Predictable costs: fixed Class 50 helps avoid reclass and reweigh charges, improving LTL rate accuracy.
• Clear NMFC identification speeds receiving at railcar shops and fabricators, reducing dwell and handling time.
• Lower claim risk through proper bundling and blocking, protecting precision-formed sills and floor assemblies.
• Non-hazardous designation broadens carrier options and shortens compliance checks for faster tendering.
