NMFC 50540 - Clay Chimney Flues & Linings | Class N/A

To find the correct freight class for your shipment:

1. Describe the commodity precisely on the BOL: “clay chimney flues/pipe or flue linings, earthenware, NMFC 50540,” and mark as non-hazardous.
2. Palletize or crate vertically with separators; pad edges and ends with foam or corrugated, add corner boards, then band and stretch-wrap. Use “Do Not Top Load” labels.
3. Load for stability: keep center of gravity low, avoid overhang, and use blocking/bracing for longer pipe sections. Fork openings should be accessible on the long side.
4. Document piece count and dimensions, photograph packaging before pickup, and request limited handling or fragile service notes for masonry job-site deliveries.

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

• Damage reduction from proper crating/palletizing cuts OS&D claims and replacement costs on brittle fired-clay parts.
• Clear commodity naming under NMFC 50540 helps avoid reclass and reweigh disputes when the class is not specified.
• Non-hazardous status streamlines paperwork and speeds dock processing, improving transit reliability.
• Forklift-ready pallets and accurate dims support better LTL pricing and fewer accessorials during pickup and delivery.
