## What Is Freight Density?

Freight density refers to the measurement of how much space a shipment occupies in relation to its weight. It is determined by calculating the weight of a shipment in pounds per cubic foot (PCF). The higher the weight per cubic foot, the denser the shipment is, and the lower the weight per cubic foot, the less dense the shipment is.

In the world of freight transportation, the classification of a shipment is determined based on its density. The National Motor Freight Classification (NMFC) is a standardized system that categorizes freight shipments based on their density, value, and other characteristics. Shipment classification is crucial in determining the cost of transportation, as carriers charge higher rates for shipments with higher classifications.

If the density of a shipment is low, it means that the shipment occupies more space in proportion to its weight, making it more expensive to transport. Conversely, denser shipments are more cost-effective to transport because they take up less space relative to their weight.

Calculating the freight density of a shipment is important when using a density-based freight carrier or when the NMFC for the shipment is Not Otherwise Indicated (NOI). To determine the correct classification for your shipment, you need to know its freight density. You can use a freight density calculator to determine your cargo’s density and corresponding freight class in seconds.

In short, Freight density is a measure of the weight of a shipment in relation to its size or volume, and it plays a critical role in determining the cost of transportation. Knowing your shipment’s density is essential for accurate classification and cost calculation, and using a freight density calculator can help make this process quicker and more efficient.

## What Is A Freight Density Calculator?

A Freight Density Calculator is an online tool that helps shippers and carriers calculate the density of a shipment to determine its freight class. The tool asks for the shipment’s dimensions, weight, and origin and destination zip codes and uses this information to calculate the pounds per cubic foot (PCF) of the shipment.

The PCF is an essential factor in determining the shipment’s freight class, which in turn affects the shipping costs. A shipment with a lower density (higher PCF) will have a higher freight class and, therefore, cost more to ship than a shipment with a higher density (lower PCF).

A Freight Density Calculator simplifies the calculation process, allowing shippers to quickly determine the density of their shipment and calculate the shipping costs. Many online freight providers offer free Freight Density Calculators as part of their online tools and resources.

## How Do You Calculate Freight Density?

Calculating freight density is an important step in determining the cost of shipping a freight shipment. Freight density refers to the weight of the shipment in relation to the amount of space it occupies. Freight carriers use this information to classify shipments and determine the appropriate cost of transportation.

To calculate freight density manually, you will need to know the weight and dimensions of your shipment. The weight should be measured in pounds or kilograms, and the dimensions should be measured in inches or centimeters. The three dimensions you will need to measure are length, width, and height. Once you have this information, you can follow the steps below to calculate the freight density:

Step 1: Calculate the total volume of the shipment in cubic feet. To do this, multiply the length, width, and height of the shipment in inches. For example, if the shipment measures 48 inches long, 40 inches wide, and 36 inches high, the total volume would be:

48 x 40 x 36 = 69,120 cubic inches

Step 2: Convert the total volume from cubic inches to cubic feet by dividing the total volume by 1,728 (since there are 1,728 cubic inches in a cubic foot). Using the example above, the calculation would be:

69,120 / 1,728 = 40 cubic feet

Step 3: Divide the weight of the shipment in pounds by the total volume in cubic feet to get the freight density in pounds per cubic foot. For example, if the shipment weighs 1,200 pounds, the freight density would be:

1,200 / 40 = 30 pounds per cubic foot

In this example, the freight density is 30 pounds per cubic foot, meaning that the shipment weighs 30 pounds for every cubic foot of space it occupies.

Once you have calculated the freight density, you can use it to determine the appropriate freight class for your shipment. The National Motor Freight Classification (NMFC) system uses freight density, value, and other factors to classify shipments into different categories. The classification determines the cost of transportation, so it’s important to accurately calculate the freight density to ensure that you are being charged the correct rate.

The following table describes how NMFC classes relate. IMPORTANT: This does not consider any class adjustments based on handling, liability, and stowability, which can affect the class and, therefore, the cost.

• The freight shipping class is based on the density of the item.
• More dense items, such as metals and heavy machinery, have low classifications, such as Class 60 through 100.
• Fragile or large items are less dense and their freight classes range from class 125 to 500

### Three Step Freight Density Calculator Equation

The Three-Step Freight Density Equation used in FreightCenter’s Freight Density Calculator is a simple and effective way to calculate the density of your shipment. Here are the three steps involved:

Step 1: Measure the dimensions of your shipment in inches (length, width, and height).

Step 2: Multiply the dimensions together to get the total cubic inches of your shipment.

Step 3: Divide the total weight of your shipment by the total cubic inches to get the pounds per cubic foot (PCF) or density of your shipment.

The equation is as follows:

Density (PCF) = Weight of Shipment (lbs) ÷ Total Cubic Inches of Shipment × 1728

The result of the equation gives you the density of your shipment in pounds per cubic foot (PCF). This information is crucial in determining your shipment’s freight class and shipping costs.

FreightCenter’s Freight Density Calculator automates this equation to provide accurate and reliable results in seconds. The calculator is easy to use, and you can use it for free on their website.

### Freight Class Density vs. NMFC Number

Freight class density and NMFC number are two important factors used in the classification of freight shipments, which determines the cost of transportation. While they are related, they are not the same thing.

Freight class density is a measure of the weight of a shipment in relation to its volume or space. It is expressed in pounds per cubic foot (lbs/ft³). The freight density is calculated by dividing the weight of the shipment by its volume in cubic feet. The higher the freight density, the higher the freight class and the higher the shipping cost.

The National Motor Freight Classification (NMFC) number, on the other hand, is a standardized code assigned to a specific commodity or product based on its characteristics. The NMFC number is used to determine the appropriate freight class for the shipment, which is based on the density, stowability, handling, and liability of the product. The NMFC number is assigned by the National Motor Freight Traffic Association (NMFTA) and is used by carriers to determine the appropriate shipping rate.

The NMFC number is a four-digit code that is assigned to each commodity or product. It is used to identify the product and to determine its classification based on its characteristics. The NMFC number is used in conjunction with the freight density to determine the appropriate freight class for the shipment. The freight class is a number from 50 to 500, and the higher the number, the higher the shipping cost.

In general, commodities with a lower NMFC number and a higher freight density are assigned to a higher freight class, and therefore, have a higher shipping cost. For example, a shipment of bricks would have a higher NMFC number and a higher freight density, resulting in a higher freight class and higher shipping cost than a shipment of pillows, which have a lower NMFC number and a lower freight density.

In summary, freight class density and NMFC number are both important factors in determining the cost of shipping a freight shipment. Freight density is a measure of the weight of the shipment in relation to its volume, while NMFC number is a standardized code assigned to a specific commodity based on its characteristics. The NMFC number is used to determine the appropriate freight class for the shipment, which is based on the density, stowability, handling, and liability of the product.

NMFC-based freight class – The Nation Motor Freight Traffic Association (NMFTA), a nonprofit membership organization of motor carriers, created the National Motor Freight Classification® (NMFC) system to assign freight classes for a multitude of commodities.

Density-based freight class – There are two circumstances under which density, not NMFC, will determine a cargo’s freight class.

1) You are using a density-based carrier.

2) the NMFC for what you are shipping is Not Otherwise Indicated (NOI). Sometimes, that may be because you are shipping several items with different freight classes in the same crate.

The freight density of an object is the measurement of its compactness or pounds per cubic foot (PCF). Watch the video below to learn how freight density and freight class are closely related.

### How Is LTL Class Density Calculated?

LTL (Less Than Truckload) class density is calculated using the same formula as the general freight density, which is:

Freight Density (lbs/ft³) = Weight of Shipment (lbs) / Total Cubic Feet of Shipment

The total cubic feet of the shipment is calculated by multiplying the length, width, and height of the shipment in inches, and then dividing the result by 1728 (the number of cubic inches in a cubic foot).

The LTL carrier will typically measure the shipment and determine the freight density before assigning a freight class. The LTL class density is used to determine the appropriate freight class, which is based on the density, stowability, handling, and liability of the product.

The LTL class density is an important factor in determining the shipping cost for a LTL shipment. The higher the LTL class density, the higher the freight class and the higher the shipping cost. LTL carriers will also take into consideration the distance the shipment needs to travel, the origin and destination locations, and other factors when determining the shipping cost.

It’s important to note that LTL carriers may have their own unique requirements and formulas for calculating the freight density, and it’s best to check with the carrier to ensure the proper calculation is used for your shipment.

### Freight Density is critical.

Freight density is critical because it is a key factor in determining the cost of shipping a freight shipment. Freight carriers use freight density to calculate the freight class of the shipment, which in turn determines the shipping cost. The higher the freight class, the higher the shipping cost.

Freight density is important because it provides an accurate measure of the weight of a shipment in relation to its size or volume. This allows carriers to determine the amount of space the shipment will occupy on the truck, and to allocate space and weight capacity accordingly. This is important because carriers want to maximize their revenue by transporting as much freight as possible in the least amount of space.

Freight density is also important because it helps carriers to ensure that their trucks are not overloaded or underutilized. Overloading a truck can result in safety risks, damage to the freight, and regulatory penalties. Underutilizing a truck can result in increased fuel and maintenance costs, and lost revenue opportunities.

In addition, freight density is important for shippers because it can help them to optimize their packaging and reduce shipping costs. By packing items more efficiently, shippers can reduce the size and weight of the shipment, resulting in a lower freight density and a lower shipping cost.

Overall, freight density is critical because it is a key factor in determining the shipping cost for a freight shipment, and it plays an important role in ensuring the safety, efficiency, and profitability of the transportation industry.

## Importance of your freight’s density.

The importance of a freight’s density cannot be overstated, as it directly impacts the cost of shipping and the classification of the shipment. Here are some reasons why freight density is important:

Cost of shipping: The freight density is used by carriers to determine the shipping cost for a shipment. The higher the density, the lower the freight classification and the lower the shipping cost. Conversely, the lower the density, the higher the freight classification and the higher the shipping cost.

Efficient use of space: Freight density is used by carriers to determine the amount of space a shipment will occupy on a truck. This is important because carriers want to maximize the use of available space to transport as much freight as possible in one trip. By understanding the density of a shipment, carriers can make more informed decisions about how to pack and allocate space on their trucks.

Improved safety: Freight density is also important for safety reasons. Carriers need to ensure that they are not overloading their trucks, which can result in safety risks, damage to the freight, and regulatory penalties. By knowing the density of a shipment, carriers can better manage their weight capacities and ensure that their trucks are not overloaded.

Optimal packaging: Knowing the density of a shipment can help shippers to pack their items more efficiently. By reducing the size and weight of a shipment, shippers can lower the freight density, resulting in a lower shipping cost. This can help shippers to save money on shipping and make their products more competitive in the marketplace.

The importance of a freight’s density cannot be overlooked. By understanding the freight density of a shipment, carriers and shippers can make more informed decisions about how to allocate space, manage weight capacities, and optimize packaging. This can result in cost savings, improved safety, and a more competitive marketplace.

## How Freight density and Other Factors Affect Freight Rates

As a shipper, it’s essential to understand the various factors that determine the cost of shipping your goods. Freight rates are influenced by multiple factors, including package dimensions, weight, distance, and freight class. However, one crucial factor that significantly affects freight rates is the density of your shipment.

Freight density is calculated by dividing the weight of the shipment by the cubic feet it occupies. The density of a shipment is used to determine its freight class, which, in turn, determines the cost of shipping. The higher the density, the lower the freight class, and the lower the shipping cost. Conversely, the lower the density, the higher the freight class, and the higher the shipping cost.

Another factor that can impact freight rates is the package’s dimensions. Carriers have limited space on their trucks, and larger packages take up more space, resulting in higher shipping costs. The weight of the package is also a factor that can impact freight rates. Heavier packages require more fuel and labor to transport, resulting in higher shipping costs.

The distance a package travels can also affect the shipping cost. Longer distances require more fuel and labor, resulting in higher shipping costs. Finally, freight class is determined by the density, stowability, handling, and liability of a shipment. The higher the freight class, the higher the shipping cost.

## What if an NMFC number cannot classify your commodity or product?

If an NMFC number cannot classify your commodity or product, it means that your product is classified as “Not Otherwise Indicated” or NOI. In such a case, you need to determine the density of your shipment to calculate the freight class. The freight class is determined by the density, stowability, handling, and liability of the shipment.

To determine the density of your shipment, you need to measure the length, width, and height of the package and multiply them together to get the total cubic inches. Then, divide the weight of the package by the total cubic inches to get the density of the shipment.

Once you have determined the density of your shipment, you can use a freight density calculator to determine the freight class. A freight density calculator will ask for the shipment’s dimensions, weight, and origin and destination zip codes, and will use this information to calculate the freight class and shipping cost.

It’s essential to ensure that you accurately determine the density of your shipment to avoid overpaying for shipping costs. Additionally, you should work with a reputable carrier that has experience shipping your type of product to ensure that it’s handled properly and delivered on time.
