1. What is Freight Class in LTL Shipping?

Definition: Freight class is a standardized classification system (ranging from 50 to 500) used by carriers to categorize LTL (Less Than Truckload) shipments based on density, value, and handling requirements.

Purpose: It helps determine shipping rates and ensures proper handling of different types of freight.

2. How Does the Freight Class Calculator Work?

The calculator uses the formula:

Where:

• Weight — Total shipment weight in pounds (lb)
• Volume — Total shipment volume in cubic feet (cu ft)
• Density — Calculated as weight divided by volume (lb/cu ft)

Explanation: The calculator first computes the density (lb/cu ft) of your shipment, then maps this value to the appropriate freight class based on standard NMFC classifications.

3. Importance of Freight Class Calculation

Details: Accurate freight class determination helps:

• Obtain accurate shipping quotes
• Prevent reclassification fees
• Ensure proper handling of goods
• Optimize shipping costs

4. Using the Calculator

Tips:

• Measure exact weight (including packaging)
• Calculate volume (Length × Width × Height in feet)
• For multiple items, sum weights and volumes
• Round dimensions up to the nearest foot

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between freight class and freight density?
A: Density is the weight-to-volume ratio (lb/cu ft), while class is the standardized category based on density plus other factors.

Q2: Why does lower density mean higher class number?
A: Lower density items take more space relative to their weight, making them less efficient to ship, hence higher class (and cost).

Q3: What if my commodity has a specific NMFC number?
A: Some commodities have predetermined classes regardless of density. Check NMFC guidelines for your specific item.

Q4: How accurate is this calculator?
A: It provides a good estimate based on density, but final class may be affected by special handling, liability, or NMFC rules.

Q5: What's the most common freight class?
A: Class 70 is common for many industrial goods, while Class 50 is typical for high-density items like machinery parts.
