Calculate Freight Density

What is Freight Class?

In most cases, your truckload freight shipping cost is based on the weight and dimensions of the goods being shipped. To make this simple and uniform, the National Motor Freight Traffic Association (NMFTA) came up with the National Motor Freight Classification (NMFC). The NMFC creates a standard that assigns specific classes to certain types and sizes of freight. The classification compares different goods and commodities being shipped. Every product shipped can fall into varying freight classes. The different freight classes are represented by numbers 50-500.

How is Freight Class Determined?

There are several characteristics that help determine freight class. The factors that influence freight class are: density, stowability, handling and liability.


Density might be the most important factor in determining freight class. In the simplest terms, freight density is your item’s pounds per cubic feet. Lower density items tend to have a lower freight class, and therefore a lower price. Density calculation is important.


Stowability accounts for how simple it is to move or stow your particular commodity. If your item contains hazardous materials or is an awkward size or shape it might have a higher freight class, which translates into a higher price.


Handling considers how often the commodity has to be touched while en route to its final destination. If it needs to stop at multiple terminals along the way or requires special handling, it becomes difficult to handle. This can result in a higher freight class, which can increase the cost of shipping.


Liability takes several factors into account. Is the item delicate and could be damaged easily during transport? Is it frequently stolen? Is it perishable? Answering yes to these questions increases the liability risk of transporting the item. The higher the risk, the higher the freight class.
You can use our handy calculator to determine freight class. You just need to know the length, width, height and weight of your commodity and input these figures into the calculator.
