NMFC 106380 – Mine Props (Steel Supports) | Class 50

To find the correct freight class for your shipment:

1. Bundle straight lengths tightly with steel strapping at 3 points and wood dunnage; keep ends flush and cap or tape sharp edges (e.g., 10 props per bundle).
2. Place bundles on sturdy skids or in steel racks sized to the prop length; block and chock to prevent rolling and mark safe lift points for forklifts.
3. List clearly on the BOL: “Mine props (supports), iron or steel — NMFC 106380 — Class 50 — Non-Hazardous.” No density entry is required for this item.
4. Flag long pieces at booking; most carriers apply ‘extreme length’ fees over 96 in. Add length notes and request appointments where mine site access is restricted.

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

• Predictable costs: Fixed Class 50 reduces reclass disputes and surprise invoices tied to density calculations.
• Lower damage risk: Racked or banded steel bundles handle well in LTL networks, cutting claims and downtime underground.
• Faster turns: Standardized bundles speed loading at shafts and depots, reducing detention and improving crew utilization.
• Simpler compliance: Non-hazardous status streamlines paperwork and avoids hazmat surcharges or special handling requirements.
