DOT Hazard ClassesFreight classes mentioned in these guides are density-based estimates for shipment planning. They are not official NMFC classifications or NMFC item-number lookups. Actual classification may also depend on value, handling requirements, liability, stowability, dimensions, packaging, and other commodity-specific factors. Confirm the applicable NMFC item number and final freight class with your carrier, broker, or an authorized NMFTA resource before shipping.
