NMFC 184140 - Iron Column/Concrete Clamps, Loose | Class 70

To find the correct freight class for your shipment:

1. List on the BOL as “Clamps, column or concrete, iron, loose” with NMFC 184140 and Class 70 to prevent reclass fees.
2. Band loose iron clamps tightly on a pallet using steel or heavy poly strapping; add edge protectors and a slip sheet to stop abrasion and punctures.
3. Separate sizes or styles with dividers and mark piece counts on two sides so jobsite receivers and rental yards can reconcile quickly.
4. Keep pallet heights manageable; dense iron hardware can overload decks—target under 1,500 lb per pallet and block sharp ends to avoid freight damage.

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

• Predictable budgeting with fixed Class 70—no density calculations or surprise reclass bills.
• Non-hazardous hardware streamlines carrier selection and cuts accessorial risk for construction supply shipments.
• Accurate NMFC 184140 usage reduces disputes and accelerates claims resolution if loss or damage occurs.
• Tool Group listing improves quote speed and comparability across LTL carriers for recurring clamp moves.
