What is Freight Class 300?
Freight class is a standardized system used in transportation to categorize and rate different types of freight based on their characteristics. The National Motor Freight Classification (NMFC) system assigns a specific class rating to each shipment based on density, stowability, handling, and liability. This rating is critical in calculating shipping rates for less-than-truckload (LTL) shipments, as it affects space and handling requirements.
What determines Freight Class?
DENSITY
The density of a commodity is identified by its dimensions and weight. Freight class code 300 should have a density of 2-3 pounds per cubic foot.
STOWABILITY
Will your freight need to be loaded with special equipment? If the size and shape of the items you are shipping require a lift or a dock it will influence your freight class determination since the carrier will have to spend more time loading and unloading your freight.
LIABILITY
Will your carrier need to take extra precautions to keep your freight safe? If you are shipping rare or highly valuable items that might be prone to theft that will affect your freight class determination since the carrier will have to make special arrangements.
HANDLING
Will the packaging of your freight allow for other items to easily fit in the carrier’s trailer? Shipping sporting products like canoes and kayaks that can’t have anything packed on top of them impacts the capacity of the carrier and, ultimately, your freight class determination.
