When shipping your products as LTL (less-than-truckload), you have to assign your shipment a freight code. This is a standardized code created by the National Motor Freight and Traffic Association which allows carriers to identify qualities of the shipment and assist with transportation.
Ship aluminum accurately by using the information below:
With or without metal or mineral filling, in packages
Aluminum - 37230
Often, NMFC codes have subclasses. These subclasses generally are based on the density of the shipment.
In this instance, the commodity, aluminum, is further broken down in the following subclasses:

Please note: This is for educational purposes only. Ultimately, the carrier reserves the right to classify the groups.
National Motor Freight Classification (NMFC) is the freight classification system that was created by the National Motor Freight Traffic Association (NMFTA) and is used for all interstate, intrastate, and foreign commerce movement of LTL cargo. NMFC codes provide standardized freight classes to determine the transportability of most of the countless different commodities that are shipped together in LTL shipments each year.
How is the cost of freight determined?
Your freight cost is determined by a number of variables, such as how far your shipment needs to go, the freight class number, whether or not accessorials are needed, as well as fluctuating fuel costs and truck capacity.
Why is the freight class of some commodities fixed?
Some items, such as car transmissions, have a specific class no matter how heavy or big they are. This is called a fixed class. Items can be assigned a fixed class if the value and transportability very rarely change.
