What is my Freight Class?

Freight Rate Central

Freight class definitions can be confusing, especially for those who are not experienced in freight shipping. There is an array of different ones to choose from, and picking the wrong one can cost you both precious time and money.

So why do we use freight classes? They are designed to help set a common and standardized freight price for shipments. This is handy when you have to work with a number of freight companies, different carriers, warehouses, and brokers, and ensures you know you’re getting a fair price.

The National Motor Freight Traffic Association (NMFTA) defines the classes, and is made available through the National Motor Freight Classification (NMFC).

The NMFTA defines the classes based on four transportation characteristics, and they are as follows:

Density: Which is the weight per cubit foot;

Stowability: Which is the length and width based on carrier mode rules;

Handling: An evaluation of the care that will be involved in transport, and;

Liability: Which includes the freight price per pound, susceptibility to theft, liability to damage, breakability, and perishability.

Using these four characteristics, the NMFTA has defined 18 different freight classes, ranging from a low class of 50 to a high class of 500. Typically, the lower the class, the lower the charge is for shipment.

Following are all the freight classes and descriptions:
