Cube rate
Considerable attention has recently focused on development of a simplified method of transportation pricing. Typically called cube or density rates, the new approach replaces the 18 traditional freight classifications of the NMFC with five cube groupings. Under the cube concept, shippers complete a cube shipping document, which replaces the traditional bill of lading. To further identify freight characteristics, shippers provide the total weight of both stackable and nonstackable freight included in the shipment.
