The freight class is mainly based on the density of the shipment.
More dense items such as steel and machinery have low classifications such as Class 50 through 85.
Fragile or bulky items fall into freight classes 125 to 500.
The formula to determine the density of an item is:
LxWxH / 1728 = Cubic Feet (CU FT), Weight (Pounds)/CU FT = Density (#PCF)
