Each item that ships in the US moves under a freight class; there are 18 classes in total ranging from 50 - 500. Freight classes are defined by the National Motor Freight Traffic Association (NMFTA). Carriers rate and ship freight based on freight class.
When quoting with Freightview, entering the correct freight class is crucial for obtaining an accurate rate. Any discrepancies will be subject to price increases or adjustments after pick up. And remember, even though you may have contracted rates or a certain percentage discount, those discounts do not always apply to adjusted or second invoices for charges added after pickup.
One way to determine the correct freight class is to reach out to your local carrier representative or terminal directly.
