In the world of LTL freight shipping, understanding the principles of shipping density can sometimes be half the battle. Once your first question about a shipment becomes, “What is our density?”, you’ll be a shipping pro in no time.
The formula for calculating density can be broken down into a few, easy steps.
Now that we have our shipping density, or pounds per cubic foot, what is our Freight Class?
Freight class is almost always determined by where the density or poundage per cubic foot falls on the Full Range Density Chart (see below)
|Class 400||Less than 1|
|Class 300||More than 1, but less than 2|
|Class 250||More than 2, but less than 4|
|Class 175||More than 4, but less than 6|
|Class 125||More than 6, but less than 8|
|Class 100||More than 8, but less than 10|
|Class 92.5||More than 12, but less than 15|
|Class 85||More than 12, but less than 15|
|Class 70||More than 15, but less than 22.5|
|Class 65||More than 22.5, but less than 30|
|Class 60||More than 30|
We know that our density for this shipment is 13.73, therefore based on the scale above, our freight class would be Class 85 as 13.73 is more than 12 but less than 15 in terms of pounds per cubic foot. Now, whenever you are quoting this shipment it should be quoted at Class 85 so that the shipment is appropriately priced. However, factors apart from density can affect the price of a shipment.
