What Is Freight Class?

Freight class is a standardized classification system used throughout the transportation and shipping industry to categorize freight based on specific characteristics. This system helps carriers, freight brokers, and shippers determine shipping costs and manage logistics efficiently.

The most widely used freight classification standard in North America is the National Motor Freight Classification (NMFC) system, which groups freight into classes numbered from 50 to 500. Each class corresponds to certain attributes of the freight, such as density, stowability, handling, and liability.

Why Freight Class Matters

Determining the correct freight class is crucial because it directly impacts:

Shipping Costs: Freight class is a major factor in calculating freight charges. Misclassifying freight can lead to unexpected fees or disputes.

Freight Handling: Proper classification helps carriers understand how to safely handle your shipment.

Logistics Efficiency: Knowing the freight class ensures better planning for storage and transportation.

Key Factors that Determine Freight Class

Freight class depends on four primary factors:

Density: The weight of the freight relative to its volume.

Stowability: How easily the freight can be stored or stacked.

Handling: The level of care required to handle the freight safely.

Liability: The risk of damage or theft during transportation.

Among these, density is the most significant factor because it provides an objective measure that correlates closely with shipping costs.

How to Calculate Freight Class

Calculating freight class might seem complicated, but it primarily revolves around determining your shipment’s density and then matching that to the NMFC classification standards
Measure Dimensions and Weight

Weight: Use a scale to measure the weight of your shipment in pounds (lbs) or kilograms (kg).

Dimensions: Measure the length, width, and height of your shipment using a tape measure or ruler. Be sure to measure in consistent units, typically inches or centimeters.
Calculate Volume

Calculate the shipment volume in cubic feet (or cubic meters).
Determine Freight Class from Density

Use the density to determine the freight class according to NMFC guidelines. Here’s a general density-to-class mapping:
Density in Freight Class

Density is the most important factor in freight class determination because it reflects how much space a shipment takes up in relation to its weight.

High-density freight (heavy for its size) generally falls into lower freight classes, which cost less to ship.

Low-density freight (light and bulky) falls into higher freight classes, leading to higher shipping rates.

Volume’s Role in Freight Classification

Volume is directly linked to density. Larger volume with lower weight leads to lower density, which increases freight class and shipping costs.

Accurate volume measurement ensures:

Correct density calculation.

Proper freight classification.

Better logistics planning and packaging optimization.
Dimensions Units in Freight Class Calculations

Consistency in units is vital. Common units include:

Weight: Pounds (lbs) or Kilograms (kg)

Dimensions: Inches or Centimeters
