NMFC 165410 - Rail Car Bolsters & Buffers | Class 50

To find the correct freight class for your shipment:

1. List NMFC 165410 and Class 50 on the BOL with the description “Body or Truck Bolsters or Buffers, railway car or locomotive.” No density entry is required.
2. Mount each bolster or buffer to heavy hardwood or steel-deck skids using through-bolts in existing mounting holes, then steel-band with edge guards to prevent strap bite.
3. Protect precision areas: cap threads, cover machined faces, and wrap with rust-inhibiting film. Immobilize any floating components and verify nothing protrudes beyond the skid footprint.
4. Mark lift points and center of gravity for safe handling. Keep the load forkable from two sides and block to prevent rolling; avoid stacking to reduce compression damage.

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

• Predictable pricing: a fixed Class 50 eliminates density-based reclass risks and inspection fees for these heavy steel assemblies.
• Lower cost per pound on stout parts, making outbound builds and inbound MRO shipments to railcar or locomotive shops more economical.
• Simplified tendering across LTL or partial truckload since carriers see a consistent NMFC code and clear handling plan, reducing accessorial surprises.
• Damage reduction from skid mounting and surface protection shortens repair cycles and keeps rolling stock projects on schedule.
