When shipping freight, you may come across the acronym N.O.I. This standards for Not Otherwise Indicated. Not every item is classified by the National Motor Freight Classification index. In these cases, shippers may need to call for real-time NOI freight rating. If you're unsure of your class, use our handy calculator below.





How to Determine Your Freight Class

Freight rates are determined by several different factors including package dimensions, weight, distance and freight class, as well as your packages' Pounds per Cubic Foot (PCF) or density. Your package’s PCF is closely related to the freight class that is applied to your freight shipment. A low PCF will result in a higher class rating. In turn, a higher class rating corresponds to a higher cost to ship your freight.

For example, a shipment that works out to 1.31 pound per cubic foot and weighs 100 pounds (Class 300) will be much more expensive to ship than an item that has the same weight but equates to 9.67 pounds per cubic foot (Class 100). In other words, the more space your freight occupies on a truck or in a container the more costs you will incur for transport. If your commodity or product cannot be classified by a National Motor Freight Classification (NMFC) number, than apply a general class rate or NOI (Not Otherwise Indicated) class to determine your cost to ship. NOI shipping terms are typically quoted and processed manually through select freight carriers.

For this reason, shippers are encouraged to make sure their weights and dimensions are accurate in order to avoid billing adjustments based on PCF and class changes. By far the most common reason for a re-bill or billing adjustment, it is also the most avoidable. Never guess or estimate dimensions and weights when shipping freight.
