NMFC 52320 - Smokestack Collar, Iron/Steel | Class 60

To find the correct freight class for your shipment:

1. List the item as NMFC 52320, Class 60 on the BOL and note it is non-hazardous; no density declaration required.
2. Choose a pallet that exceeds the collar’s OD and block the inner bore with wood to prevent crush; avoid pallet overhang.
3. Guard sharp flanges with edge protectors and corrugated wrap; cover bolt patterns to prevent snagging and add VCI or stretch film if moisture is a risk.
4. Band through the bore or around the base using steel or heavy poly straps, add 4-way forklift access, and mark center of gravity for larger bases.

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

• Fixed Class 60 rating helps secure lower LTL rates compared to higher classes, improving margin on heavy steel components.
• Non-hazardous designation broadens carrier options and reduces accessorial hurdles, speeding tender-to-pickup times.
• Simple, non-density classification cuts reweigh/reclass disputes and the fees that come with them.
• Proper skid blocking and edge protection reduce damage claims on ring-shaped bases, lowering total landed cost.
