NMFC 38670: Steel Buoy Heads | Class 55

To find the correct freight class for your shipment:

1. Secure round heads with V-blocks or ring cradles on a sturdy skid; band with steel strapping and use edge protectors. Example: pair 24" domes on a 48x48 pallet.
2. Protect surfaces from corrosion with VCI wrap or a light oil film; cap any threaded fittings and add moisture barrier if routing through humid or coastal lanes.
3. Mark center of gravity and lift points; set forklift tine spacing wide enough to avoid denting domes, and use do-not-stack cones unless crated for stacking.
4. List “Buoy Heads, steel – NMFC 38670, Class 55” on the BOL with piece count and packaging. No density needed for this fixed-class item.

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

• Predictable pricing from a fixed Class 55 rating—faster quotes and fewer reclass surprises.
• Cost-efficient for heavy steel shapes; lower class than many fabricated parts can reduce LTL spend.
• Reduced admin burden: no density calculations or cube worksheets to maintain across lanes.
• Stronger packaging guidance cuts damage risk, helping marine contractors and buoy refurbishers keep projects on schedule.
