NMFC 177910 - Air Springs in Boxes | Class N/A

To find the correct freight class for your shipment:

1. Confirm density for each boxed unit. Example: a 24x24x12 inch carton is 4.0 cu ft; at 28 lb the density is 7 pcf—use this pcf to assign the correct class per Item 170.
2. Use heavy-duty corrugated boxes with corner protectors. Shield metal end caps and inflation ports with inserts to prevent punctures through the carton.
3. Palletize with no overhang on a 48x40 pallet. Interlock layers, add slip sheets, and strap or stretch-wrap to control bounce and vibration in LTL networks.
4. Print the NMFC 177910, piece count, and density (pcf) on the BOL and carton labels. Add Do Not Crush and This Side Up to protect the bellows.

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

• Density-based rating rewards tight pack-outs; increasing pcf can reduce freight class and lower LTL charges without changing product value.
• Boxed, non-hazardous air springs are accepted by a wider carrier pool, improving service options and enabling competitive rate shopping.
• Accurate NMFC 177910 and Item 170 declarations minimize reclass fees, inspections, and billing disputes, accelerating cash flow.
• Damage-resistant packaging lowers claims and warranty returns by protecting rubber bellows and metal fittings from impact and compression.
