Freight class is the National Motor Freight Classification (NMFC) system used by shipping carriers to categorize and price different types of LTL freight.
Knowing your freight class is essential to determining shipping costs, and it can also affect how your freight is handled during transport in LTL (less than truckload) and FTL (full truckload) shipping.
The level of care needed to handle an item during shipping is a factor in determining its actual freight class. Items that are fragile, require special attention, or have hazardous properties will fall under a higher LTL shipping classes and cost more to ship. This also includes perishable cargo.
The ease of transporting the freight with other commodities is referred to as stow-ability. LTL Shipments that are perishable, flammable, or contain hazardous materials are regulated and may not be shipped with certain materials, resulting in a higher freight class that is most costly to ship.
For determining freight class, you need to know the weight and dimensions of your shipment, as well as its density. Density (pounds per cubic foot) is calculated by dividing the weight of the shipment by its volume.
Once you have these measurements, you can determine your shipment’s freight class name.
Here is a step-by-step guide to help you calculate your freight classification accurately:
Measure the length, width, and height of your shipment, including any packaging like pallets. Round up to the nearest inch.
If you have multiple pieces or pallets, repeat this step for each one.
Multiply the height, width, and length measurements you just took. This gives you the total cubic inches of the shipment. Then divide this number by 1,728 to convert cubic inches to cubic feet. If you have several different pieces, multiply the length, width, and height of each individual piece.
Determine the weight of the shipment in pounds. If you have multiple pieces, add the weight of each piece together to get the total weight. Then divide the total weight by the total cubic feet of the shipment to get the pounds per cubic foot, or density.
By following these steps, you can determine your LTL freight classes accurately and avoid overpaying by getting your freight class wrong.
If you’re unsure about any of these steps or need further assistance, feel free to contact a professional in the freight industry such as Focus West Logistics. Most LTL carrier and LTL shipping companies will be happy to help you calculate classes for your freight types.
The NMFC Classification book contains a freight density (measured in pounds per cubic foot) and class chart that lists the different freight classes and the range of densities that correspond to each class.
Using this chart can help you determine your freight class if you prefer to do it manually rather than using a calculator.
You can also consult the chart below to get a general idea of how different types of products are classified.

A pallet freight class can vary depending on its dimensions and weight, as well as the type of product it is carrying. In general, most pallets fall into the 50-70 freight class range.
For determining freight class, you need to know the weight and dimensions of your shipment, as well as its density. Density (pounds per cubic foot) is calculated by dividing the weight of the shipment by its volume. Once you have these measurements, you can determine your shipment’s freight class name.
You can get your freight class by calculating your shipment’s density and consulting the NMFC Classification book or using a freight class calculator.
The class of your freight shipment depends on its density, stow-ability, handling, and liability. You can determine your freight class by using a freight class calculator and inputing your shipments dimensions, weight, and density, and consulting the National Motor Freight Classification book.
The class of your freight shipment is used to determine the price you pay for shipping. It takes into account factors such as freight density, stow-ability, handling, and liability. Knowing your freight class is essential to ensuring that you are paying the correct price for your LTL shipment.
NMFC code is the same as freight class. If someone is asking you for your NMFC code, it is the same as a freight class. The National Motor Freight Classification (NMFC) is a standardized system used by carriers to assign a freight class to specific products. Using the correct freight classification for your shipment is essential to ensure that your freight is classified correctly and priced accordingly.
