    What is Freight Class?

    Comprising the full truckload (FTL), less-than-truckload (LTL), and partial truckload (PTL), carriers and freight forwarders provide shippers with various shipment choices.

    In the United States or across the US/Canada border, freight class is a way of classifying less than truckload (LTL) freight.

    This type of freight is utilized by both domestic and US carriers, who use the NMFC (National Motor Freight Classification) to price their freight.

    When using somewhat smaller freight, such as less than truckload shipment (LTL), you should take the freight class into consideration. It makes the pricing approach considerably equitable by standardizing freight costs.

    Factors that Determine Freight Class

    National Motor Freight Classification (NMFC) classifies all products, and that classification serves as the basis for establishing a product's class for all major carriers.

    NMFC utilizes four factors to classify a product’s freight class, these include density, stowability, handling, and liability.

    Each of these factors that determine the freight class are described below:


    Classification used to describe items that are difficult to load and carry is represented as stowability. When shipping freight, most of it usually stows on trucks, ships/boats and trains.

    There are certain commodities, however, that are subject to governmental or carrier rules, and certain products will not be able to be loaded simultaneously.

    For instance, hazardous items are delivered following a certain method and are governed by special rules. Moreover, the packages that are too heavy, long, or have unusual dimensions might make it difficult to load with other freight.


    The more valuable the commodity, the greater the freight rates will be. A carrier will take into consideration if the probability of theft or damage is high, as well as the potential harm caused by a single shipment to another consignment.

    For instance, potentially hazardous compounds are treated have higher class than standard nuts and bolts.

    Ease of Handling

    The items that have unique handling need, because of their size, weight, or level of endarkenment. They thus demand careful attention and treatment to be transported in freight.

    Merchandise handling therefore is taken into consideration when determining the freight class. Handling is a factor to consider when giving a class to product that has uncommon or substantial handling characteristics.


    The density in freight class relates with the amount of space and weight of the product in the trailer, as well as pallet utilization.

    The general rule to determine freight class is the smaller the density, the higher the classification. Smaller, heavier, and denser products fall into a lower-class category and are cheaper to send.

    How many Freight Classes are there?

    Your freight class is determined by the NMFTA, and this is referred to as NMFC abbreviated for National Motor Freight Classification. The freight class of your item dictates the shipping costs for the carrier.

    Freight classification has 18 different classes, starting with class 50 (the least costly) and ending with class 500 (the most expensive). The freight class is based on what is in the shipment, and what NMFC number is assigned to it.
