NMFC 118150 - Sheet Metal Fan Cones | Class by Density

Note 118152: NOTE-The term 'unfinished' includes those articles which have been blanked, stamped or shaped, and which require additional forming or shaping operations before assembly.

To find the correct freight class for your shipment:

1. Calculate density before quoting: measure the packed length, width, and height, then weight. Example: 40 lb on 36x36x18 in equals 13.5 cu ft; 40/13.5 ≈ 2.96 PCF (lower density tends to higher class).
2. Package to protect thin edges and flanges: nest cones or bells to boost density, cap nozzles, add edge guards, and use foam or corrugated sleeves to prevent crush.
3. Palletize or crate irregular shapes: strap shrouds and rings to a pallet with blocking to stop roll, or use a plywood/triple-wall crate for large venturis; avoid overhang and mark lift points.
4. Follow Item 170 and the note for 118152: label as air inlet/discharge sheet-metal parts, include NMFC 118150 on the BOL, and confirm carrier accepts density-based classing.

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

• Optimize costs by nesting and right-sizing packaging to increase PCF, lowering the resulting freight class and improving LTL rates.
• Reduce damages and claims on thin-gauge sheet metal by reinforcing flanges and rims, cutting rework and downtime in HVAC and industrial fan lines.
• Faster quotes and fewer reclass fees with clear NMFC 118150 identification and accurate density data on the BOL.
• Broader carrier options and simpler routing since the item is non-hazardous, keeping transit flexible and competitive.
