There is no such thing as free freight! All operating costs and profits for "free freight shipments" are covered under cost-of-goods-purchased:

  • The consignee does pay with an inflated invoice cost. Please contact GNTS for assistance in completing a thorough examination of your inbound freight costs.

When you should call for volume rates depends on the type of product you are shipping, however there are some general guidelines. If your shipment meets or exceeds one of the following parameters, please contact GNTS for a rate comparison:

  • Four pallets or more
  • 8+ linear feet
  • 750+ cubic feet
  • 4000 pounds or greater.

A shipment's density is one of the factors that determines the freight rate. Shippers need to know how to calculate a shipment's density so they can properly describe their goods on the bill of lading. The total weight of the shipment is divided by the total cubic feet to determine the density.

Step 1. Measure the height, width and depth of the shipment in inches. Measure to the farthest points, including skids or other packaging.

* On shipments with multiple pieces, repeat step 1 for each piece.

Step 2. Multiply the three measurements (height x width x depth). The result is the total cubic inches of the shipment.

* If you have multiple pieces, multiply the height x width x depth for each piece. Take the results for each piece and add them together to get the total cubic inches.

Step 3. Divide the total cubic inches by 1,728 (the number of cubic inches in a cubic foot). The result is the cubic feet of the shipment.

Step 4. Divide the weight (in pounds) of the shipment by the total cubic feet. The result is the pounds per cubic foot, ie., density of the shipment.

* For multiple pieces, be sure to add the weight of each piece together before dividing by the total cubic feet of the shipment.
* Round fractions to the nearest full cubic foot number.

For example, if the skid weighs 500 pounds with dimensions of 42 inches x 48 inches x 48 inches:

  1. Multiply 42" x 48" x 48" = 96,768 cubic inches
  2. Divide 96,768 by 1,728 = 56 cubic feet
  3. Divide 500 pounds by 56 cubic feet = 8.9 pounds per cubic feet (PCF), ie, density of shipment
