What is Freight Class 77.5?

Freight Class 77.5 is the classification most appropriate for tires, snowplows, bathroom fixtures, and garments including shirts and pants that weigh 13.5-15lbs per cubic foot. Less-than-truckload shipping uses a freight classification system determined by the National Motor Freight and Traffic Association to help shippers and carriers effectively communicate the transportability of their freight. Freight class determination is based on four categories; density, stowability, liability and handling. How much your freight weighs in relation to its size, whether or not it will fit in the trailer easily with other freight, if it’s at risk for theft or if it will need special loading equipment are all factors that need to be considered when determining the appropriate freight class.
