What is Freight Class?

You must assign your shipment a freight code when shipping products as LTL (less-than-truckload) freight. This standardized code, which is issued by the National Motor Freight and Traffic Association, allows carriers to identify qualities of the shipment to help with transportation.
Ship casings accurately by using the information below:

Subclasses for

Casings - 33780

Having multiple subclasses is fairly common for NMFC numbers. These subclasses are primarily based on the density of the shipment.
In this instance, the commodity, casings, is further broken down in the following subclasses:

FAQs

How can I determine NMFC codes?

An organization named the National Motor Freight Traffic Association (NMFTA) publishes a list of freight class designations, codes, and subclasses for frequently shipped commodities (https://classit.nmfta.org/). You must pay a subscription fee to view it. Find more information about freight classes from the experts at Koho for free on our freight classes pages.

What is the purpose of freight classification?

Freight classification groups products based on similar density, stowability, handling and liability so carriers and shippers have an effective way of communicating the ease of transporting said freight.

What is density?

Density is the relationship between weight and size. A ping pong ball, which is very little material surrounding a good amount of air, is low density. Bricks, which are heavy for their size, are high density. In LTL shipping, it is commonly measured in pounds per cubic foot.
