What is Freight Class?

There are millions of people in the United States with jobs in the trucking industry, however, not all are familiar with freight class.

They could be involved in the industry for a decade and they could have some knowledge of the types of freight.

Particularly, I would also mention here the truck drivers which are known as the heroes of the highways.

Notably, the truck drivers would go miles in order to transport the cargo, would take the road challenges without any additional knowledge.

Additionally, they would go through the process of truck driver training and get a CDL license but they would not keep further knowledge of freight.

If you are not among the experienced truck drivers or the professional truckers, the freight class determination is rather confusing.

what is freight class and what you need to know about

There are dozens of fact which at first make it difficult to understand.

However, it is not impossible to acquire.

According to The National Motor Freight Classification (NMFC), the freight class determination is similar to the other grading systems available in other industries.

freight class and its determination in trucking companies

On the subject of this, The National Motor Freight Traffic Association (NMFTA) defines the freight in classes.

To emphasize, freight class means establishing the commodity of transportation.

In addition, NMFC is classifying the commodities into classes, and there are 18 of them to be precise.

freight class types

Correspondingly, the 18 classes of freight are determined into further, detailed classification. In particular, the freight classes range from 50 to 500.

To continue with, these freight classes are created in order to help you with your trucking business.

In other words, the classes will help you get standardized pricing for your freight transportation when working with carriers, brokers and warehousing companies.

Things To Keep In Mind About Freight Class

Once you have seen the freight classes, you must assume that you can learn them eventually. You are right, you can.

However, there are things to keep in mind.

The database can be updated by NMFTA at any time. Correspondingly, the determination and classification of particular goods can be changed.

freight class - things to keep in mind

The good thing is, if you happen to have a problem with your shipment and the class codes, you can always contact your freight brokers.

This procedure is made in order to make sure that your shipment will arrive where it needs to, on a budget and on time.

In the worst case, you can contact NMFTA to help you interpret your freight class.

What Factors Go Into Determining Freight Class?

As shown above, the freight classes could be complex. Due to this matter, they are determined by several factors.

In addition, they are determined in order to ease the entire process of classification. More importantly, to ease the shipping for trucking companies.

To emphasize, they are determined by the transportability of the cargo.

freight class - factors that determine it

In addition to the above-mentioned, NMFC characterizes these classes into specific details. In this way, the entire process of freight class could be easily understood.

Those characteristics of the freight are the following:

  • Density
  • Stowability
  • Handling
  • Liability

All of these characteristics or factors are a crucial part of the freight class. Having said this, you will find out from the definition of each of them as follows:


According to the density, the freight is classified into 50 pounds per cubic. Having said this, there is a further classification of the density, assigned by The Commodity Classification Standards Board (CCSB).

Notably, the density is classified into 70, 92.5, 175 and 400 freight density, to 15, 10.5, 5 and 1 pound per cubic.

freight class - density

More importantly, the freight which has less density than 1 pound is classified as 500. To put it in another way, the density is actually a space the items preoccupy.

Continually, the item’s volume in cubic goes like this:

Length, Width, and Height

To explain, the density is calculated by dividing the item’s weight in pounds and the item’s volume in cubic feet.

freight class - length width and shape

In order to emphasize the above-mentioned, dimensions are usually measured in inches. Furthermore, the density of the item equals the weight of a volume of your freight.

Continually, the weight is measured in pounds while the volume is measured in cubic.

Stowability – The size and shape of the commodity

Most of the freight is transported by trucks, while the rest is hauled by boats and trains, and all of these types of freight are regulated by policies or the Government.

With regards to cargo loading, there is a certain rule stating that some cargo types are prohibited to mix together. For example, hazardous materials transportation includes a specific way of hauling and is always transported separately due to the flammability.

freight class - stowability

On the other hand, the extreme trucking with excessive weight or length, also makes other freight impossible to load together, and these are the rules everyone obeys.

The stowability classification shows the difficulty and complexity of loading the items which for some trucking companies in the United States create additional charges and need of more fleet.

Ease of Handling – The care needed for the freight

Usually, most of the freight loading involves mechanical equipment and there are no difficulties during the process.

freight class - ease and difficulty of handling

However, as shown above, there are fragile items, excessive weight items or hazardous materials that require special handling. Regarding the difficulty or the ease of handling of the items, the freight has further classifications.

Liability – Theft, damage or perishability

Another factor determining the freight class is the liability. It is a possibility of freight damage or freight theft.

For instance, the hazardous cargo, as well as the perishable cargo, are prone to combustion or explosion which are classified based on the liability factor.

Continually, the freight involves classification by value per pound and density, representing a fraction of the delivery liability.

Once you get to know the important factors describing the freight class, you may think is hard but it is not impossible to learn.

On the subject of this, it is not hard, there are only numbers to remember.

Although there are 18 freight classes, there are only 5 as the most common and they are the following:

  • Class 60 (30 – 35 pounds per cubic foot)
  • Class 70 (15 – 22.5 pounds per cubic foot)
  • Class 85 (12 – 13.5 pounds per cubic foot)

To continue with, besides their common knowledge in the trucking industry, a trucking company owner needs to know to determines its freight class that is not available on the list.

Accordingly, the list is the following:


Why you need the list of freight class codes?

To continue with, there are the NHTSA, FMCSA, DOT, DOL, DMV etc. Although just part of the regulations of the United States, every human in the trucking industry needs to know these.

What is Freight Class Density Calculator

Usually, the lower the density – the higher the freight classification. As explained previously, besides the density as the main factor in freight class, there are other characteristics as well:

  • How your freight fits in the carrier truck
  • The Handling of Freight
  • How perishable, breakable or fragile is your freight

Practical Example How To Determine LTL Freight Class

On the other hand, if you are a small transportation company, you can do the freight class yourself.

Although some may think that might be easy to determine the LTL freight class, on the contrary, it is difficult. Having said this, there are some rules regarding the determination and calculation of it.

In order to properly classify a cargo of a single pallet, you need the dimensions and weight of that particular pallet.

freight class - how to determine ltl freight classes

For instance, if the dimensions are 48”L x 40” W x 45.5 the weight of the cargo including the pallet is 243.4 pounds.

Using this formula, you derive the PCF of 4.8 PCF. Here is an example of the full 32 cartons pallet measurement:

Length x Width x Height = Cubic Inches (48” x 40” x 45.5” = 87,360 Cubic Inches)

freight class factors

Cubic Inches/1728 = Cubic Feet (87,360/1728 = 50.6 Cubic Feet)

Here you divide the unit’s weight by the volume:

243.2 lbs. /50.6 cubic feet = 4.8 lbs per cubic foot

Things To Remember:

Density is the primary key in determining freight class, however, the characteristics in some cases have a very profound effect on the class and therefore the cost.

Simply put, the density is the pounds per cubic foot of your item. Typically, lower freight classes represent items of higher density and therefore a lower cost.


To sum it up, the knowledge of freight class codes can help you determine the cost of the cargo your company is transporting.

Generally speaking, knowing the classes and details about freight, results in providing efficient and economical shipping for clients.
