NMFC 166410 – Refrigerator Car Doors | Class 70

To find the correct freight class for your shipment:

1. List the commodity as “Doors, Frames, Racks or Sections for refrigerator cars – NMFC 166410, Class 70” on the BOL, and note any attached hinges, latches, or lock bars.
2. Crate door panels A‑frame style with edge protection; wrap gaskets and insulated cores, add moisture barrier, and band to a skid. Block and brace loose racks or frames to prevent roll or slide.
3. Call out handling needs: center‑of‑gravity labels, minimum fork length, and no side clamp use on insulated panels. Request liftgate, appointment, or flatbed if facility constraints apply.
4. Even with fixed Class 70, include accurate piece count, weight, and dimensions for carrier space planning and to avoid cubic or oversize fees; photograph packing as claim documentation.

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

• Fixed Class 70 classification reduces reclass/rebill risk and keeps invoices clean and predictable.
• One NMFC covers doors, frames, racks, and sections, simplifying rating and speeding MRO shipments to rail shops and depots.
• Proper crating protects gaskets, foam insulation, and hardware, cutting OS&D, warranty replacements, and downtime for refrigerated rolling stock.
• Predictable class enables sharper LTL rate negotiations and clearer mode decisions (volume LTL vs partial TL) for heavy steel or insulated sections.
