How to Determine Your Class
To find the correct freight class for your shipment:
- Quote as Class 500, SU modular building; note plastic-faced honeycomb walls/roof and plywood-faced honeycomb floor in the description to avoid reclass.
- Load on a rigid, full-length skid with wide runners; block and brace, through-bolt where possible, and pad plastic faces with non-abrasive foam and edge guards.
- Lift using a spreader bar and slings attached to the frame, not the panels; mark lift points and center of gravity, and avoid point loads on the honeycomb skins.
- Prep for transit: secure doors and windows, remove or pad lighting, cap any wiring, weatherwrap for road spray, and book volume LTL/flatbed if oversize.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Fixed Class 500 eliminates density math, speeding quotes and reducing billing disputes.
- Clear SU designation minimizes carrier handling, lowering damage risk on fragile honeycomb skins.
- Non-hazardous status broadens carrier options and simplifies tendering and paperwork.
- Cost control levers: volume LTL or partial TL, backhaul lanes, and packaging that reduces claim exposure.
