Understanding Freight Class and Its Impact on Shipping Costs

Freight class is a crucial element in the logistics and shipping industry, playing a significant role in determining the cost of shipping goods. Understanding how freight class works can help businesses and individuals manage shipping expenses more effectively. Here's a breakdown of what freight class is and how it impacts shipping costs.

What is Freight Class?

Freight class is a standardized categorization system developed by the National Motor Freight Traffic Association (NMFTA). It classifies freight into different categories, each assigned a number known as a “class.” This number helps carriers calculate shipping costs based on specific characteristics of the goods being transported. There are 18 primary freight classes, ranging from 50 to 500, and the classification depends on four key factors:

1. Density: The weight of the shipment relative to its size (pounds per cubic foot). Denser shipments usually have lower freight classes, meaning they're less costly to ship.
2. Stowability: How easily the freight can be loaded and stored with other items. Oddly shaped or bulky items may fall into higher classes, increasing shipping costs.
3. Handling: The ease with which the shipment can be handled during transit. Fragile or difficult-to-handle items are assigned a higher class, as they require special care.
4. Liability: The risk of damage or theft during shipping. High-value or perishable goods often have higher classes due to the increased risk involved in transporting them.

How Freight Class Impacts Shipping Costs

Freight class directly influences shipping rates. Lower-class freight (e.g., class 50) is typically less expensive to ship because it’s dense, easy to store, and less likely to be damaged. On the other hand, higher-class freight (e.g., class 400 or 500) is more expensive due to its bulk, fragility, or high value.

For example, shipping a pallet of heavy steel parts (class 50) is generally cheaper than shipping a lightweight, fragile sculpture (class 200). Therefore, accurately determining your freight class ensures that you're neither overcharged nor undercharged, leading to more predictable shipping costs.

Why Accurate Freight Class Matters

Misclassifying freight can result in unexpected fees or delays. If a shipment is assigned the wrong class, carriers may reclassify the shipment upon inspection, often leading to additional charges known as "reclassification fees." Ensuring accurate freight classification from the beginning helps avoid these extra costs and ensures smooth shipping processes.

How to Determine Your Freight Class

While density is one of the most critical factors in determining freight class, it’s essential to consult with the NMFTA's freight class guidelines or work with a carrier to classify your shipment properly. Freight calculators and online tools are also available to help businesses ensure they’re choosing the right class based on the nature of their goods.

Conclusion

Freight class significantly impacts shipping costs and plays a pivotal role in the logistics process. By understanding how your shipment’s size, weight, and characteristics affect its classification, you can better manage shipping expenses and avoid unnecessary charges. Proper classification leads to smoother logistics, transparent pricing, and more efficient business operations.
