1. What is Freight Class?

Freight class is a standardized classification system used in the transportation industry to categorize commodities based on their characteristics. It helps determine shipping rates and is based on factors including density, stowability, handling, and liability.

2. How Does the Calculator Work?

The calculator determines freight class based on density (pounds per cubic foot):

Where:

• Higher density = Lower class number (better shipping rates)
• Lower density = Higher class number (higher shipping rates)

Explanation: The calculator uses a standard density-to-class lookup table that is widely accepted in the freight industry.

3. Importance of Freight Class

Details: Correct freight class determination is crucial for accurate shipping quotes, avoiding reclassification fees, and ensuring proper handling of goods.

4. Using the Calculator

Tips: Enter the density of your shipment in pounds per cubic foot (lb/ft³). The calculator will return the corresponding freight class.

5. Frequently Asked Questions (FAQ)

Q1: What if my shipment has multiple items with different densities?
A: Calculate the total weight and total volume first, then determine the overall density.

Q2: Are there other factors besides density that affect freight class?
A: Yes, stowability, handling, and liability can also affect the class, but density is the primary factor.

Q3: What's the difference between class 50 and class 500?
A: Class 50 is for very dense items (≥50 lb/ft³) with lowest rates, while class 500 is for very light items (<1 lb/ft³) with highest rates.

Q4: How do I measure density for my shipment?
A: Weigh your shipment, measure its dimensions (L×W×H in feet), then calculate density as weight/volume.

Q5: Do all carriers use the same class system?
A: Most use the NMFC standard, but there may be minor variations between carriers.
