A shipment’s density is one factor that determines the freight rate. Shippers need to know how to calculate a shipment’s density so they can properly describe their goods on the bill of lading. The total weight of the shipment is divided by the total cubic feet to determine the density.

If the shipment is palletized, use the dimensions of the pallet, the combined height of the carton and the pallet, and the total weight of the shipment. When determining the dimensions of your shipment, be sure to measure the longest sides including any packaging, overhangs or protrusions.

Once your density has been calculated you may refer to the table to get the class of your shipment.

NOTE: For freight with a height of 47″ or more the density is
calculated with a height of 96″ because freight cannot be stacked.

The density calculator is to be used as a guide. If further clarification is required please contact our office at (603) 881-3350 ext 226.
