## How To Calculate Freight Class For Density Based Items

#### Since most of the major trucking companies in the US choose to participate, it’s important to understand the simple calculations involved for density based items under this standard.

##### Below is an example of how to correctly calculate freight class for any items that fall under a density category in the NMFC. Several categories of items are density based such as plastic articles, lighting fixtures, and various sporting goods products.

Step 1.  Multiply the length X width X height in inches of each pallet or crate you’re shipping and add the total/s together.

Step 2. Divide that total by 1728 (This converts inches into cubic feet).

Step 3. Now take the total weight and divide that by the total cubic feet.

Example. 2 pallets at 48x48x48 and 300 lbs each pallet

48x48x48 x2 = 221,184

221,184/1728 = 128 Cubic Feet

300 lbs x 2 = 600 lbs / 128 Cube = 4.68 or 4.68 PCF (lbs per cubic foot)

Step 4. Find the PCF listed on the class chart below and viola you have successfully calculated your freight class!

 400 Less than 1 PCF 300 1 but less than 2 PCF 250 2 but less than 4 PCF 150 4 but less than 6 PCF 125 6 but less than 8 PCF 100 8 but less than 10 PCF 92.5 10 but less than 12 PCF 85 12 but less than 15 PCF 70 15 or greaterPCF
