One of the major responsibilities of transportation managers is to obtain the best possible rating for all products shipped, so it is useful for members of a traffic department to have a thorough understanding of the classifications system. Although there are differences in rail and truck classifications, each system is guided by similar rules. It is possible to have a product reclassified by written application to the appropriate classification board. The classification board reviews proposals for change or additions with respect to minimum weights, commodity descriptions, packaging requirements, and general rules and regulations. An alert traffic department will take an active role in classification. Significant savings may be realized by obtaining an improved classification for a product or by recommending a change in packaging or shipment quantity that will reduce a product’s rating.
