The first step to quoting any freight shipment is figuring out what freight class your shipment falls into. The easiest way to do that is to use a freight calculator.

All you have to do is put in your measurements and it will tell you what class your freight falls into.

Why Do You Need a Freight Class?

Carriers use the freight class among other information to determine your rate. It is vital that you have an accurate class to ensure your rate is correct. Otherwise you risk a rate adjustment and surprise additional charges.

What Is a Freight Class?

Freight classes are a standardized classification based on the density of the item. Carriers can make more money on small dense items than they can on large light items. Because of this, rates can vary greatly and it is vital your get the correct class.

How to Calculate Freight Class

If you choose to do your calculations by hand, you need to know the four factors that go into figuring out the freight class.

Density

To calculate density you need to know the dimensions and weight of your shipment.

Density = Mass/Volume

As the formula states, divide the total mass by the total volume to find out density.

Stowability

How easy is your item to move and pack into a truck? The more careful the carrier has to be, the higher your freight class will be.

This could be because your item is extremely heavy, or an odd shape, or cannot have anything stacked on top of it.

Volume= Length x Width x Height

Handling

Similar to stowability, any shipment that requires special handling will get a higher freight class.

Liability

The carrier doesn’t want to take on any more liability than they have to. Because of this, shipments that increase liability get a higher freight class.

This includes shipments that are hazardous, breakable, or perishable.

How Is Freight Different From Parcel?

Parcel shipping is for smaller items and letters. If a single human can lift and carry it, then you can probably ship it by parcel. If your item is large or over 150 pounds, then it is best to ship it by freight.
