NMFC 178040 – Torsion Springs, Loose/Packaged | Class N/A

To find the correct freight class for your shipment:

1. State packaging on the BOL: “torsion springs, loose” or “torsion springs, packaged,” and list material (carbon or stainless) and accurate piece count to align with NMFC 178040.
2. For loose coils, contain them in a rigid bin or crate with dividers; tie bundles, cap sharp ends, and use VCI paper or oil wrap to protect finishes during transit.
3. For long springs (e.g., garage door or industrial), load into corrugated or PVC tubes with end caps, then strap to a pallet with edge protectors; keep within pallet footprint to avoid overlength issues.
4. Prevent tangling and unwinding by spiral wrapping coils and securing layers; avoid heavy freight stacked on top and mark cartons or bins with “Do Not Crush.”

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

• Clear NMFC 178040 identification reduces reclass disputes and unexpected carrier chargebacks, keeping quotes aligned with invoices.
• Flexible handling—covered for loose or packaged—lets manufacturers and distributors choose bulk flow or protective packing to balance speed and damage control.
• Non-hazardous status streamlines paperwork and removes hazmat surcharges, improving dock throughput and pickup reliability.
• Contained loose bins and palletized tubes cut touchpoints and preserve coil integrity, lowering claim risk and improving dimensional efficiency for LTL pricing.
