A Freight Class Calculator is an online or digital tool that helps you determine the freight class of your shipment. Freight class is used in LTL (Less Than Truckload) shipping. It helps carriers decide how much they will charge to transport your goods. Freight class is based on four main factors: density, stowability, handling, and liability. Among these, density is the most common factor. Density means how heavy your product is compared to the space it takes up. The Freight Class Calculator mainly uses weight and dimensions to calculate density.. https://freight-classcalculator.com/
