HSN stands for Harmonized System of Nomenclature. It is a system for classifying commodities created by the World Customs organization. U.S. LTL shipping, however, uses NMFC classifications instead.
The class determines the cost of the shipping. The lower the class, the lower the cost.
No, not all commodities have freight subclasses, although many do.
