NMFC
Freight classes are catalogued by the National Motor Freight Classification tariff. Less-than-truckload shipments are typically rated based on their class. The class of your freight is determined by its contents. Different types of products have different costs associated with them, based primarily on their value and density, fragility, and handling characteristics of the product.
There are 18 possible freight classes ranging from Class 50 (the least expensive) to Class 500 (the most expensive). It’s important to have the correct class—too high and your rate will be costly. Too low, and a carrier can reclassify your shipment to a higher class, which will result in a rate change.
