NMFC 165690 - Steel Car Retarders | Class 70

To find the correct freight class for your shipment:

1. List NMFC 165690 on the BOL and describe the freight as “steel car retarders or parts” to prevent miscoding as generic steel hardware.
2. Palletize or crate heavy steel segments; add edge protectors and at least two steel bands per axis, with blocking to stop rolling or shifting.
3. For long retarder bars, bundle by length with hardwood dunnage and forkliftable spacers; request liftgate or forklift-capable pickup when docks aren’t available.
4. Apply light oil or VCI wrap to bare steel if storage is expected; cover with weatherproof sheeting to guard against corrosion between yard transfers.

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

• Fixed Class 70 rating delivers predictable LTL quotes and reduces reclass fees on dense steel components.
• Non-hazardous designation streamlines booking and avoids extra compliance steps or hazmat surcharges.
• One code for complete assemblies and parts simplifies procurement and consolidates shipments across rail projects.
• Proper unitization (pallets/crates) speeds cross-dock handling, lowering claim risk and minimizing detention or redelivery costs.
