  1. Multiply the length, width, and height (42 x 46 x42) to get the total cubic inches (81,444) .


  2. Divide the total cubic inches by 1,728 to get the total cubic feet (47).


  3. Divide the weight of the shipment (500 lbs.) by the total cubic feet (47). This will give you a density of 10.65.

Looking at the chart, we see that because of our crated packaging type, the top 4 subgroups are applicable. 10.65 falls under the subgroup 3, or class 92.5. In this class example, it is important that dimensions and weight are accurately measured in order to calculate the true density (and appropriate class) for the shipment. It's also crucial to note once more that packaging makes a huge impact. See how high the classes jump if the product is palletized or in packages other than secure crates or boxes.

LTL services are in higher demand than ever before. National freight carriers are in the driver's seat, and doing what they can to limit troublesome shipments - including those with a low density and high freight class. Once you've optimized your shipments for carriers, many shippers wonder about whether a Freight All Kinds (FAK) agreement may be a worthwhile perk. Next, we'll take a look at what goes into that FAK and if it's right for your business.  The freight specialists at PartnerShip can guide the way so you aren't stuck staring at your calculator, and a high freight bill.
