NMFC 165710 - Car Roofs KD or Roof Parts Steel | Class 50

To find the correct freight class for your shipment:

1. Build rigid skids or A‑frame racks for long, thin steel roof panels; add edge guards, dunnage, and tight banding to prevent flexing and metal‑to‑metal rub.
2. Protect bare steel from corrosion with VCI wrap or poly plus desiccants, then cap with corrugated sheets; label Keep Dry and Do Not Top‑Load.
3. For LTL, aim for consolidated bundles that fit standard handling (e.g., 48x96 in footprints) and coordinate overlength handling or side-load service when pieces exceed norms.
4. State the commodity clearly on the BOL: “Car roofs, KD or roof parts, steel, NOI – NMFC 165710, Class 50, non-hazardous,” and include piece counts and skid dimensions.

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

• Lower shipping spend from a fixed Class 50 rating on dense steel parts, often yielding better per‑pound LTL rates than higher classes.
• Simple, non‑density classification reduces quote friction and reclass penalties when paperwork and packaging match the NMFC description.
• Non‑hazardous status broadens carrier options and avoids hazmat surcharges, streamlining tendering and transit.
• Durable racks and corrosion control lower claim risk and rework costs, keeping railcar production or refurbishment schedules on track.
