NMFC 41740 - Air-Inflatable Casters & Supports | Class 150

To find the correct freight class for your shipment:

1. Deflate bladders fully, cap valves, and bag hoses and manifolds before boxing to prevent punctures from loose fittings or sharp edges.
2. Separate steel or aluminum plates from inflatable pads using corrugated dividers and 2 in foam; add edge guards so hardware can’t abrade the air cells.
3. Mark kits clearly: list caster size, pad count, hose lengths, and accessory hardware; add “Do Not Cut With Knife” to protect bladders during receiving.
4. On the BOL, reference NMFC 41740 Class 150, note piece count and “boxed”; density is not required, reducing the chance of reclass or inspection delays.

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

• Predictable rating: fixed Class 150 eliminates density calculations, speeding LTL quotes and tendering for air‑inflatable handling kits.
• Lower reclass risk: packaging in boxes matches tariff language, minimizing additional charges and disputes with carriers.
• Fewer handling restrictions: non‑hazardous components move easily across carrier networks, improving lane coverage and lead times.
• Better claim outcomes: clear item description and protective boxing reduce transit damage and strengthen documentation if issues arise.
