NMFC 131840 - Tractor Exhaust Pipes | Class 77.5

To find the correct freight class for your shipment:

1. Use package-ready packing: bundle or box pipes, cap each end, wrap with VCI or film, and add edge/corner protectors to prevent dents and surface rust.
2. Mount long pieces on a full-length skid to avoid overhang; secure with 2-inch straps every 4 feet and use V-blocks so bent sections aren’t crushed.
3. Mark the BOL with NMFC 131840, “Tractor Exhaust Pipes, steel—further processed,” and Class 77.5 to prevent reclass and speed dock handling.
4. If attachments (brackets, hangers, sensors) ship in the same package, isolate them with foam or corrugated partitions to avoid scratching the tube.

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

• Predictable rating: fixed Class 77.5 simplifies quoting and benchmarking across LTL carriers—no density calculations needed.
• Lower reclass risk when NMFC 131840 and package-style packing are used, reducing surprise charges and post-delivery disputes.
• Non-hazardous status eliminates hazmat fees and paperwork, accelerating tender-to-pickup for dealers, OEMs, and farm operations.
• Package-friendly handling moves cleanly through cross-docks, cutting damage exposure and the cost of replacements or expedites.
