How Do I Calculate Freight Class?

How do I calculate freight class? You do so  by using four transportation factors. These factors being: stowability, liability, ease of handling and density. Our freight class calculator helps shippers easily calculate their freight class. This is based on standard shipment details.


The calculations are used for shipments transported by LTL freight shipping. Not all items are identified by freight class. These are identified as (NOI)Not Otherwise Indicated. When identified as NOI, the shipment becomes a Density Based Shipment. Freight Center is happy to assist in determining your shipments type. Whether your specific item is identified by freight class or density.

Density Based

You use Density shipping for shipments of objects that vary in size. In addition, when the number of items shipped varies between locations. Some examples of density items are wooden tables and clothing. You use Wooden Tables for density shipping based due to how they vary in size. Clothing may seem similar due to their vast variety of sizes. However, it is actually due to how the shipper could be transporting as much as 500 pounds, or as little as a ton. Determining whether or not your item would be part of these types of shipments are not too hard. However, FreightCenter is happy to assist and shall be able to determine this for you with ease.

How Stowability Calculates in Freight Class

Stowability is the first and main calculation of all shipping companies. Calculations are taken into account whether or not your item can be transported amongst other commodities. Items that can become enflamed, are hazardous, or perishable, cannot be shipped amongst certain materials. We recommend keeping your shipment within a crate or box. This would then make your shipment an easier thing to stack and pack within a cargo container or truck.

Calculating the value of your item is discovering its liability. Shipping companies refer to the liability as the likelihood of theft and or damage attempts to their vehicle. Liability is very important to them, especially for shipments that involve longer drives. Possessing an item with a greater risk results in a higher freight class. We here at FreightCenter are happy to assist in discovering your item’s liability.

How Density Calculates in Freight Class

Your item is given a lower freight class when it is an High density (heavy and compact) item. Those are less susceptible to damage. Shippers give low density items a higher freight class when they are more susceptible to damage. Density is how much the item weighs in relation to its size. Shippers measure by cubic feet. The measurement determines the amount of space needed for the item. Your item is given a lower class, when compact, and is cheaper to ship than bulkier items.
