Freight Class Explained: How It Impacts Your Shipping Costs
Freight class explained is one of the most important concepts for businesses shipping palletized goods, yet it is often misunderstood. Many companies focus on carrier rates but overlook how classification directly affects what they pay for every shipment.
Freight class is determined by a combination of density, handling requirements, liability, and stowability. In practice, this means that how you package and palletize your products can significantly change your shipping cost — even if the weight stays the same.
Why Freight Class Explained Matters for Your Operation
Understanding freight class explained allows businesses to make smarter decisions when preparing shipments. Carriers assign a class number, typically ranging from 50 to 500, where lower classes are cheaper and higher classes are more expensive.
Shipments that are dense, well-packaged, and easy to handle typically fall into lower classes. On the other hand, bulky, lightweight, or unstable loads often get assigned higher classes, increasing cost per shipment.
This is where packaging plays a critical role. Using oversized boxes, leaving empty space inside cartons, or building inefficient pallets can increase your freight class without you realizing it.
For example, two shipments with the same weight can be priced very differently if one takes up more space or is harder to handle. That difference is not about the carrier — it is about how the shipment was prepared.
Improving density is one of the most effective ways to lower freight class. This can be achieved by right-sizing boxes, reducing void fill, and stacking cartons efficiently to maximize pallet height. Stronger corrugated boxes also allow safer stacking, which directly contributes to better density.
Another common issue is pallet overhang or unstable loads. When shipments are not properly contained with stretch film or strapping, carriers may reclassify them due to handling risk. This often results in unexpected charges after delivery.
Reducing freight class is not about cutting corners — it is about aligning packaging and shipping strategy. When boxes are correctly sized, pallets are stable, and loads are properly secured, shipments become easier to handle and more cost-efficient.
Companies that understand freight class explained treat packaging as part of their logistics strategy rather than a separate task. This approach not only reduces shipping costs but also improves consistency, reduces damage, and simplifies operations.
Before your next shipment, take a closer look at how your products are packed and palletized. Small adjustments in packaging can lead to meaningful savings across your entire shipping operation.
