NMFC 25770 – Cast Iron Boiler, KD Flat | Class 65

Note 25771: NOTE-Surfaces and components liable to be damaged must be fully protected.

To find the correct freight class for your shipment:

1. Pack cast iron heat‑exchanger sections KD flat in sturdy cartons with rigid edge protection; band multiple packages together or onto a skid to keep pieces from shifting.
2. Print NMFC 25770 and Class 65 on the BOL and outer labels; reference the note for item 25771 so carriers recognize the KD flat packaging criteria.
3. Use moisture barrier wrap and desiccant for iron parts; bag hardware, gaskets, and controls in a clearly labeled kit to prevent loss during unload.
4. Prearrange liftgate and residential/jobsite access if no dock; mark Do Not Stack if flat‑packed sections could crack under top freight.

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

• Predictable costs with a fixed Class 65 rating—fewer reclasses and inspection delays versus density‑based items.
• KD flat packaging reduces cube compared to assembled boilers, improving LTL rates and trailer utilization for distributors and HVAC wholesalers.
• Non‑hazardous status broadens carrier options and simplifies tendering, helping you secure capacity fast during heating season spikes.
• Clear NMFC 25770 documentation supports claims defense and minimizes ancillary fees tied to misclassification or improper labeling.
