Frequently asked questions
Does Estes use the standard freight class scale?
This calculator uses NMFTA's current standard 13-band full-density table. Check that your commodity's NMFC item and Estes Express Lines's tariff use that table; commodity-specific provisions or carrier tariffs can give a different class.
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.
