FREIGHT CLASS EXPLANATION

Determining the right freight classification

Shipments that are sent as LTL (less-than-truckload) are typically rated per hundred pounds and fall into a class range between 50 to 500. There are a total of 18 classes and each is used in determining the rate, the lower the class the less than rate and vice versa.

The NMFC (National Motor Freight Classification) determines the class for every product and is the standard by which all major carriers use when determining a products class. When determining the class for a product the NMFC uses four characteristics; density, stowability, handling and liability.

A significant amount of class applications require the density to determine the actual class, this is done multiplying the height, width and length in inches then dividing by 1728 to determine the cubic footage. Take the weight and divide the cubic footage into it to determine the PCF, (pounds per cubic foot), again this helpful in many instances when determining the proper NMFC class.

If you are unsure of your products class or density please call us for assistance and we will gladly provide you with the correct information, our expert staff has years of experience in applying the correct MFC codes.
