Unraveling Freight Class with FuseFreight

When it comes to freight shipping, one concept stands out: freight class. At FuseFreight, we know that understanding this term can make a huge difference in your shipping costs and efficiency.

What is Freight Class?

Freight class refers to the National Motor Freight Classification (NMFC) system, which categorizes commodities into 18 classes – from Class 50 to Class 500. These classes are used to standardize freight pricing across the logistics industry.

How is Freight Class Calculated?

The NMFC determines the freight class of a commodity based on four factors:

  1. Density: The space an item occupies relative to its weight.
  2. Stowability: The ease with which an item can be stowed in a truck with other freight.
  3. Handling: How easy or difficult an item is to handle during transportation.
  4. Liability: The potential for theft or damage, and the perishability of the item.

Factors Determining Freight Class

The freight class is primarily determined by the item’s density, with lower density items typically falling into higher freight classes (and vice versa). However, other factors like stowability, ease of handling, and liability can also affect the freight class.
