Disclaimer: This freight class calculator is provided for informational and estimating purposes only. It is accurate based on your inputs, but actual freight classification is determined by the LTL carrier and may vary based on the shipment's dimensions, weight, density, packaging, commodity and other applicable factors. All LTL shipments are subject to inspection, reweighing and reclassification by the individual carrier, which may result in additional charges.
