The Commodity Classification Standards Board (CCSB) assigns classifications 70, 92.5, 175 and 400 to freight with densities of 15, 10.5, 5, and 1 pound per cubic foot, respectively. Freight less dense than 1 pound per cubic foot is classified as 500. The density is the space the item occupies in relation to its weight. The density is calculated by dividing the weight of the item in pounds by its volume in cubic feet.
