Enter piece count, dimensions, and total weight to see the estimated class.

Classes follow the standard NMFC density scale (lb/ft³). True NMFC classification also considers stowability, handling, and liability, and some commodities carry fixed classes regardless of density — confirm the published NMFC item for your commodity before booking.
