Freight class is a standardized classification system (NMFC) used in LTL shipping to determine rates. Classes range from 50 (densest, cheapest) to 500 (least dense, most expensive).
Freight class is primarily determined by density (weight per cubic foot), but also considers stowability, handling requirements, and liability factors. Density is the most common method.
Lower density items take up more space relative to their weight, reducing the carrier's ability to maximize truck capacity. This results in higher freight classes and shipping rates.
Increase density by using smaller packaging, removing void fill, or bundling multiple items together. Every cubic inch saved can potentially lower your freight class and reduce costs.
“Eliminated freight class disputes. We know exactly what to expect before shipping.”
- Mark D., Warehouse Manager
“Helped us optimize packaging and reduce LTL costs by 20%. Essential tool for our team.”
- Jennifer W., Logistics Director
“Quick, accurate freight class calculations. The density breakdown is very helpful.”
- Carlos M., Freight Broker
Our Freight Class Calculator helps shippers, freight brokers, and logistics professionals determine NMFC (National Motor Freight Classification) freight classes for LTL shipments. Accurate freight class determination ensures proper pricing and prevents costly re-classifications.
The NMFC system classifies freight into 18 classes ranging from 50 to 500. Lower classes (50-85) are for dense, heavy items that are easy to handle and stow. Higher classes (150-500) are for lighter, bulkier items that take up more space. Understanding your freight class helps you negotiate better rates and avoid shipping delays.
