NMFC 52340 - Steel Smokestacks, NOI | Class N/A

To find the correct freight class for your shipment:

1. Quote and book under NMFC 52340, then flag any piece over 8–12 ft as long freight; list max length and piece count clearly on the BOL.
2. Unitize sections by nesting cones or stacking flat panels; band to hardwood skids with 4x4 dunnage every 4–6 ft, add edge guards, and cap flanged ends.
3. Protect bare steel from moisture with VCI wrap and poly, label “keep dry,” and note finish (painted or galvanized) to prevent abrasive contact during handling.
4. Plan loading for overlength items: request side-load or curtain-side service; for 12–28 ft pieces, compare volume LTL vs partial TL to reduce linear-foot charges.

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

• Accurate NMFC reference reduces reclass fees and shortens disputes, while non-hazardous status streamlines documentation and pickup approvals.
• Robust bundling and dunnage mitigate OS&D on long, rigid components, avoiding replacement costs and jobsite delays.
• Nesting sections and optimizing unit lengths cut cubic footprint and linear-foot fees, improving LTL rates and routing options.
• Using carriers equipped for overlength freight curbs special handling accessorials and supports on-time project installations.
