Freight classes for commodities in this category are defined in the National Motor Freight Classification (NMFC), established and maintained by the National Motor Freight Traffic Association (NMFTA) . Proper classification depends on four transportation characteristics: density (Pounds Per Cubic Foot), handling, stowability, and liability.
Packaging standards for commercial transport are benchmarked against International Safe Transit Association (ISTA) test series and U.S. DOT cargo safety requirements to prevent carrier re-classification and freight damage claims.
