Before using a Freight Class Calculator, it is important to understand what freight class means. Freight class is a system used to classify different types of cargo. In the United States, this system is created by the National Motor Freight Traffic Association (NMFTA). It divides shipments into 18 different classes, from Class 50 to Class 500. Freight class is mainly based on four factors: density, stowability, handling, and liability. Density is the most important factor. It is calculated by dividing the weight of the shipment by its volume.. https://freight-classcalculator.com/
