NMFC 180930 - Iron Buoys, Empty or Gas-Filled | Class 85

To find the correct freight class for your shipment:

1. List NMFC 180930, Class 85 on the BOL to ensure accurate rating for iron buoys. Class is fixed, but include dimensions and weight for pricing and space planning.
2. Stabilize round shells with cradle skids or V-blocks and chocks. Band to a pallet using edge protectors; e.g., a 36 in buoy strapped to a 48x48 skid.
3. Guard lift eyes, vents, and weld seams with padding. Mark Do Not Stack and This Side Up to prevent rolling and top load damage during cross-dock moves.
4. If gas-filled, verify the fill is air or inert gas and that plugs are tight. Note “gas-filled, non-hazardous” on paperwork to avoid hazmat miscoding.

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

• Single Class 85 coverage for empty or gas-filled units reduces reclass risk and surprise carrier adjustments.
• Non-hazardous status eliminates hazmat fees and simplifies carrier selection across LTL networks.
• Proper cradling and blocking minimize shell dents and seam damage, cutting claims and deployment delays.
• Clear dims and skid footprints help avoid oversize and handling surcharges, keeping freight rates predictable.
