* Peninsula Truck Lines, Inc., is a participating carrier of the National Motor Freight Traffic Association and uses the National Motor Freight Classification (“NMFC”) to rate it's shipments. Below is a sample of a density scale and the appropriate class that is used in the NMFC for plastic or rubber articles other than expanded, NMFC item 156600. Most items have a specific listing in the NMFC. Density is a key factor in determining the classification of the freight, but the Commodity Classification Standards Board is also tasked to take stowability, handling, and liability into consideration when applying a class to a specific named commodity.

You can visit or call our rate department at (253) 929-2000 option 3 for further assistance in determining the class of your products.
