Disclaimer from the National Motor Freight Traffic Association

The density guidelines are used in the assignment of classes where average density is representative or reflective of the range of densities exhibited. Furthermore, the density/class relationships set forth in the guidelines presume that there are no unusual or significant stowability, handling or liability characteristics, which would call for giving those characteristics additional or different "weight" in determining the appropriate class.
