NMFC 48670 – Clock Springs in Boxes | Class 100

To find the correct freight class for your shipment:

1. Pre-stage by size and finish: bag or wrap coils in VCI poly or paper to prevent tangling and rust, then nest them in small inner cartons with partitions.
2. Select sturdy cartons: use 200# or 32 ECT boxes, add kraft or foam dunnage to remove voids, and tape in an H-pattern to keep coils from compressing each other.
3. Palletize many small cartons: interlock rows on a 40x48 pallet, add corner boards, and apply 70-gauge stretch wrap; label two sides with SKU and piece counts.
4. Document clearly: note “NMFC 48670, Class 100 – clock springs, boxed” on the BOL, mark non-hazardous, and include total carton and pallet quantities.

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

• Predictable costs with a fixed Class 100 rating reduce reclass fees and surprise adjustments.
• Non-density classification accelerates quoting and auditing, saving administrative time for LTL shipments.
• Standard boxed packaging minimizes damage to small metal parts, cutting claim rates and replacement spend.
• Non-hazardous status widens carrier selection and avoids hazmat surcharges, improving routing flexibility.
