NMFC 37640: Solid Columns | Class 70

To find the correct freight class for your shipment:

1. Book as “Columns, solid” under NMFC 37640. Do not mix with hollow, composite, or metal columns; review notes 37504 and 37662 if you have mixed materials.
2. Package on full-length skids or in custom crates. Add edge/corner protectors, wrap to limit moisture, and band over sacrificial blocks to avoid surface dents.
3. Declare the longest piece length on the BOL to avoid surprise overlength fees. Use dunnage and chocks so round or turned columns cannot roll in transit.
4. For jobsite deliveries, confirm access and unloading. Long pieces often require a forklift or boom; most liftgates are unsuitable for lengths over 96 inches.

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

• Fixed Class 70 removes density calculations, reducing reclass risk and speeding quotes.
• Correct item naming (solid columns) helps prevent inspection charges and protects negotiated LTL rates.
• Non-hazardous woodwork moves through standard networks, improving transit reliability and cutoffs.
• Durable packaging reduces finish damage and claim costs, keeping construction timelines on track.
