Subclasses for
Almost all U.S. LTL carriers use NMFC freight classes, although some are attempting to move to a dimensionally-based system.
If the couch you are shipping has not been assembled yet and you are shipping various components that you can use freight class 250. If you are shipping a complete product then you should use freight class 175.
NMFC freight classes are determined using four factors: density, handling, stowability, and liability. All of these factors affect the cost to the carrier of shipping goods.
