NMFC 51015 - Metal Culverts & Fittings | Class N/A

To find the correct freight class for your shipment:

1. List the BOL as: “Culverts, Culvert Sections or Culvert Fittings, metal, in packages — NMFC 51015,” and include bundle count, diameters, and lengths for clarity.
2. Build tight bundles on skids with 4x4 dunnage; add edge protectors under steel strapping to avoid crushing corrugations, and cap or nest ends to prevent deformation.
3. Plan for length: use three-point dunnage support for 10–20 ft sections, note any overlength on the pickup, or shift to flatbed if exceeding LTL length thresholds.
4. Keep bundle dimensions uniform and forklift-friendly; aim for manageable bundle weights (e.g., under 3,000 lb), and secure with metal bands and stretch wrap to meet packaged requirements.

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

• Avoids density reclass: this item rates by commodity, reducing reweigh/inspection fees and billing disputes.
• Damage mitigation lowers claims: proper bundling, edge protection, and end capping protect corrugated metal and fittings during LTL handling.
• Operational efficiency: combining sections and fittings into single packaged bundles cuts handling touches and may reduce accessorials.
• Predictable pricing: using the conduits group item often beats generic metal pipe density ratings, stabilizing costs across municipal and sitework projects.
