Notes
Note 172522: NOTE-Applies on shipments of components or parts necessary to construct scaffolding, scaffolds or builders' or maintenance horses, or on shipments of one or more of the named components or parts.
How to Determine Your Class
To find the correct freight class for your shipment:
- Measure and weigh every package, then calculate density (L×W×H in inches ÷ 1728 = cubic feet; weight ÷ cubic feet). Example: a 96×48×18 in bundle at 720 lb equals 48 cu ft and ~15 pcf.
- Bundle long tubes and planks tightly with banding, cap sharp ends, and strap to skids so no pieces slide out. Keep lengths uniform to avoid overlength surcharges and improve handling.
- Nest frames, gates, and guardrails to raise density and protect finishes. Use edge protectors under straps and wrap powder‑coated sections to prevent abrasion during LTL transfers.
- Box small hardware—clamps, casters, screw jacks, collars—before palletizing. Mark packages “Scaffolding or Parts, NMFC 172521,” and review Note, item 172522, for any special provisions on configurations.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Density-based rating lets you lower freight class by increasing pack efficiency—nesting frames and tight bundling can materially reduce LTL costs.
- Single NMFC for mixed scaffold components simplifies quotes and billing, cutting reclass disputes and reweigh fees from mismatched descriptions.
- Proper packaging (capped ends, boxed hardware, edge protection) reduces damage and claim risk, keeping jobsite timelines intact and labor idle time down.
- Non-hazardous commodity avoids hazmat surcharges, and using standard pallet footprints minimizes special handling and overlength accessorials.
