Freight class and chargeable weight directly affect carrier billing. Final classification depends on the National Motor Freight Classification (NMFC), commodity-specific rules, packaging, and carrier rating practices. Always verify your freight class, NMFC code, and chargeable weight with your carrier or broker before booking a shipment.

We work to keep our formulas and the NMFC density scale accurate, but we make no warranty as to completeness or fitness for a particular purpose and accept no liability for decisions made based on these tools.
