Freight shipments are assigned a freight class. Freight classes are defined by the
National Motor Freight Traffic Assocation(NMFTA) as part of their National Motor
Freight Classification (NMFC) system. The freight class of your shipment is used
to determine the shipping charges. There are 18 different classes that range from
50(least expensive) to 500(most expensive). The freight class is determined by its
contents, weight, and density.
Use our Density Freight-Class Calculator to determine the Pounds per Cubic Foot
and the freight class.
If the shipment is palletized, use the dimensions of the pallet, the combined height
of the carton + the pallet, and the total weight of the shipment.
