Freight class is a standard classification system for shipments, defined by the National Motor Freight Traffic Association (NMFTA). It's used to categorize commodities like Moldings for transport, taking into account factors like weight, dimensions, density, storage capability, ease of handling, and liability. Freight class is a system to categorize different types of goods being shipped.
Density is a key concept in freight shipping, as it significantly impacts the freight class for commodities like Moldings and hence, the shipping cost. It is calculated as the weight of the shipment divided by its volume. Density is a determinant of the freight rate in LTL shipping.
Stowability is used in freight shipping to describe how easily an item can be stowed or stored in relation to other items. For example, when trying to understand stowability for Moldings, it is important to know if the item can be packaged efficiently and stowed onto the truck easily. In other words- Stowability is how well a shipment can be packed or stored with other shipments.
Liability is a term used to refer to the accountability or risk involved in transporting Moldings. It's one of the factors considered when determining freight class. It's the risk or potential loss involved in the shipment of goods.
Handling refers to the procedures and precautions taken when moving and storing Moldings. It is one of the factors considered when determining freight class for Moldings. Handling refers to the operations involved in moving and storing freight.

For many NMFC® codes there isn’t just one single class that is applied. Often, NMFC® numbers have multiple "sub-classes", which are almost always based on the density of the shipment. In the instance where your NMFC® number has multiple sub classes, it's best to contact an expert, like Koho, to help identify which subclass to use.
An organization known as the National Motor Freight Traffic Association (NMFTA) publishes a list of freight class designations, codes, and subclasses for many commonly shipped commodities (https://classit.nmfta.org/). You must pay a subscription fee to view this list. For more information about freight classes for free on our freight classes pages.
Every commodity has both a freight class and a NMFC code. Freight class represents a category of items while NMFC codes relate to specific commodities within each of the 18 freight classes.
