FedEx Freight and freight class
FedEx Freight rates against standard NMFC classes. Its online density calculator returns the same 18-step scale used here; the NMFC item number still governs the official class.
FedEx Freight — confirm the official NMFC item for your commodity before booking.

Frequently asked questions
Does FedEx use the standard freight class scale?
Yes. FedEx Freight rates density-based commodities on the same 18-step NMFC class scale shown here. The difference between carriers is service and pricing, not the density maths.
How do I find my FedEx freight class?
Enter the shipment's weight and outer dimensions to get its density, then read the class. For commodities with a fixed NMFC item, confirm the official class with FedEx Freight.
