What is Freight Class?

Freight class refers to a standardized system in which goods are classified based on specific characteristics in the freight shipping industry. Devised by the NMFTA, or National Motor Freight Traffic Association, it assigns goods with a specific class number that ranges from 50 to 500. These classifications enable carriers to come up with shipping rates fairly and consistently across the board. The freight class of shipment is determined based on aspects of density, storability, handling, and liability. Freight class understanding develops the accuracy of quoting shipping costs and avoiding reclassification fees. Proper classification ensures that the logistics are efficiently managed, with transparency in cost.

How to Calculate Freight Class?

• Calculation of freight class requires assessing key characteristics of shipment. Measure the dimensions of the item in length, width, and height in inches first, then convert to cubic feet by dividing the volume in cubic inches by 1,728.
• Then, take its weight in pounds. To calculate the density, divide the weight by volume and get its freight class from the NMFTA freight class chart with the help of the density value.
• Also, take into consideration the handling ease, susceptibility to damage, and storage needs, for this could affect the class it will fall into. Accurate data means proper classification.

Types of Freight Class

Freight class is divided into types based on numerical ranges set by the National Motor Freight Classification, which range from Class 50 to Class 500. The types describe the cargo concerning their density, storability, handling requirements, and liability. Class 50 represents the densest and least expensive items, like bricks or motor parts, while Class 500 relates to light, bulky, or fragile items, like pillows or ping-pong balls. These classes mirror how efficiently goods use space and the associated risks, which are directly related to shipping costs. Understanding these types ensures the right classification, fair pricing, and effective freight .

Pallet Class

The pallet class describes the freight class given to shipments moved by pallets according to the NMFC system. Its classification will be made based on the nature of the goods palletized and their respective density, storability, handling, and liability. Pallet class is the crucial factor that decides the cost of shipment in LTL freight. The heavier and denser the pallets are, the lower the class; this usually brings lower rates. Heavier rates apply to lighter or fragile items. Proper identification of pallet class assures fair pricing and avoids additional reclassification fees for business shipments.

How to Calculate Pallet Class?

• To calculate pallet class, determine the density of the palletized shipment. First, measure the pallet's length, width, and height in inches to calculate its volume (L × W × H) and divide this by 1,728 to convert it to cubic feet.
• Then, divide the total weight in pounds by the volume in cubic feet to find the density in pounds per cubic foot. Compare the density now to the NMFC density chart for the freight class. Consider also handling, storability, and liability because these also may change your final class assignment.
• This will provide accurate calculations so that shipping is cost-effective and in compliance.

Freight Class Formula

The freight class formula is based on the shipment's density calculation, which is one of the primary bases for freight classification. The formula is:

• Density (lbs/ft³) = weight (lbs) / Volume (L x W x H) ÷ 1728
• Where dimensions are in inches, and the result is pounds per cubic foot. Follow up with the NMFTA chart to get the freight class after getting the density. For example, lower denatures normally fall into the higher classes due to space taken, while higher denatures usually mean lower classes.
• This calculation ensures the correct freight charges that are applied and for proper handling.

Freight Class Rate

• Freight class rate represents the transportation cost of a specific freight class, which is determined by the density of shipment, handling difficulty, storability, and liability. The carrier will use these rates to price out LTL freight, making the system non-arbitrary.
• Lower freight classes (e.g., 50) correspond to denser and easier-to-ship goods, offering lower rates, while higher classes (e.g., 500) are for fragile or bulky items, incurring higher costs.
• Freight class rates vary among carriers but are standardized by the NMFTA guidelines. Understanding these rates helps shippers plan logistics and optimize costs.

Freight Class Density Chart

• A freight class density chart is a reference document that helps correlate the density of a shipment against the freight class corresponding to it for accurate classification. Density is calculated as the weight of a shipment divided by its volume in cubic feet, and the resulting figure determines the freight class.
• Items with a density above 15 pounds per cubic foot may fall into lower classes, such as 50 to 70, while less dense items fall into higher classes, from 125 to 500.
• The chart helps shippers quickly identify the correct class, ensuring compliance with NMFTA standards and accurate shipping costs.

NMFTA - National Motor Freight Traffic Association

The NMFTA is a nonprofit organization that develops, maintains, and publishes standards and practices for the freight transportation industry within the United States. It oversees the NMFC system, which makes sure that freight is classified the same on a consistent basis and that shipping rates remain fair. NMFTA promotes better logistics with standardized freight operations that increase transparency between shippers and carriers. Its guidelines help reduce disputes and simplify the freight shipping process. More about National Motor Freight Associaltion.

NMFC - National Motor Freight Classification

The National Motor Freight Classification is the method of categorizing commodities for shipment by their inherent attributes, such as density, storability, handling, and liability. The NMFTA created the NMFC, which furthered assigning goods a specific numeric freight class to ease rate determination for LTL shipments. The NMFC provides consistency among carriers so that pricing is predictable, and logistics operate smoothly. Proper adherence to the NMFC prevents misclassification and potential penalties.

Freight Cargo

It pertains to goods or commodities that are transported by truck, ship, train, or plane in large quantities. For this reason, it basically consists of raw materials, finished goods, and equipment necessary for manufacturing industries and business establishments. Cargo freight is classified by weight, dimension, and form-nature, such as dry, perishable, or hazardous goods. All should be properly handled, packed, and documented to ensure safe and timely delivery. This efficient freight cargo management supports international trade and supply chains.

Freight Transport

Freight transportation means the movement of goods from one place to another by road, rail, air, and sea. It serves as the backbone of global trade, ensuring businesses receive raw materials and deliver products to customers. Freight transport systems are tailored to cargo type, distance, and urgency, ranging from local deliveries to international shipments. Factors like cost, speed, and environmental impact influence mode selection. Advanced logistics and tracking technologies enhance efficiency and transparency in freight transport operations

Density-Based Freight Classification

Density-based freight classification concentrates on the weight of the shipment and its volume to determine its freight class. This system is considered fair as the space the shipment is taking up is contrasted with its weight. Things that have high density have lower freight classes, hence minimizing costs when shipping, while low-density goods belong to a higher class. It forms a crucial part of the LTL freight pricing systems.

Freight Brokers

Freight brokers act as intermediaries between shippers and carriers, facilitating efficient transportation solutions. They leverage industry expertise and networks to negotiate rates, manage shipments, and optimize logistics. Brokers help shippers find the best carriers for their freight while ensuring cost-effective and timely deliveries. Their role is crucial in connecting supply chain partners.

Less-than-Truckload (LTL)

Less-than-truckload shipping is the method of shipment of small freight, which doesn't require taking a full truckload. Goods of several shippers are consolidated into one truck to optimize space and reduce costs. For shipments from 150 to 15,000 pounds, LTL is perfect. This is an economical solution, which also involves services related to tracking, loading, and unloading.

Freight Shippers

Freight shippers are businesses or individuals responsible for transporting goods to customers or other businesses. They determine the packaging, labeling, and classification of their shipments, ensuring compliance with freight regulations. Shippers collaborate with carriers or brokers to manage logistics efficiently. Proper preparation by shippers minimizes delays and optimizes costs.

Freight Carriers

Carriers are companies or other entities that offer the transportation of goods for shippers by truck, vessel, aircraft, or rail. They manage the forwarder function moving cargo, whether LTL, full truckload, or intermodal. They ensure timely delivery, tracking services, and freight handling in transit. Reliable carriers make for supply chain efficiency.

Freight All Kinds (FAK)

Freight All Kinds (FAK) is a term in shipping where various kinds of goods, supported by different freight classes, can be grouped together to obtain one simplified class. FAK agreements between shippers and reduce the administrative complexity and standardize shipping rates. This approach benefits businesses by streamlining operations and providing cost predictability for mixed cargo shipments.
