Determining freight class
Freight density plays a major factor in choosing the right freight class. By calculating your freight density, you can more accurately plan your shipment, saving you time and money.
Effective July 19th 2025, there will be two additional tiers to the classification system:
. 30-35 PCF will be class 60
. 35-50 PCF will be class 55
. 50 PCF and above will be class 50
For an accurate estimate of your shipment’s freight class, start by entering your shipment’s dimensions and weight into the calculator, adding more lines as necessary.
If you may have additional questions, please connect with an expert.
Disclaimer about NMFC standards for freight classes:
The Class number provided in the Uber Freight Density Calculator is only an estimate and does not take into account the commodity. Moreover, this calculator does not factor in possible liability or handling characteristics of the commodity. Due to these limitations, items shipped that are not classed solely based on density may be more likely to have an incorrect classification.
