Frequently asked questions
Does Estes use the standard freight class scale?
Yes. Estes Express Lines 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 Estes 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 Estes Express Lines.
