1. What is a FedEx Freight Classification Calculator?

Definition: This calculator determines the density of a shipment which is used to assign the appropriate freight class for FedEx shipments.

Purpose: It helps shippers estimate their freight classification which affects shipping costs and requirements.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \rho = \frac{W}{L \times W \times H / 1728} \]

Where:

\( \rho \) — Density (pounds per cubic foot)
\( W \) — Weight (pounds)
\( L \) — Length (inches)
\( W \) — Width (inches)
\( H \) — Height (inches)

Explanation: The formula converts cubic inches to cubic feet (1728 in³ = 1 ft³) and calculates how much weight occupies each cubic foot of space.

3. Importance of Freight Classification

Details: Freight class (based on density) determines shipping costs, handling requirements, and carrier liability. Lower density items typically have higher freight classes and cost more to ship.

4. Using the Calculator

Tips: Enter the exact weight and dimensions of your shipment. Measure to the nearest inch including packaging. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the 1728 in the formula?
A: This is the conversion factor from cubic inches to cubic feet (12×12×12 = 1728).

Q2: How does density relate to freight class?
A: Generally, lower density means higher class (e.g., 1-10 lb/ft³ = class 250, 10-15 lb/ft³ = class 175).

Q3: Should I round my measurements?
A: No, use exact measurements as rounding can significantly affect density calculations.

Q4: Does this include packaging?
A: Yes, always measure and weigh the packaged shipment.

Q5: How accurate is this for final pricing?
A: This provides an estimate. Final classification is determined by FedEx during processing.
