1. What is a CH Robinson Freight Class Calculator?

Definition: This calculator determines the density of a shipment for freight class classification according to CH Robinson standards.

Purpose: It helps shippers and logistics professionals calculate the density of their freight to determine the appropriate freight class for pricing.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

Explanation: The formula converts the shipment dimensions to cubic feet, then divides the weight by this volume to get density.

3. Importance of Freight Density Calculation

Details: Freight class is largely determined by density, which affects shipping costs. Higher density items typically qualify for lower freight classes and lower rates.

4. Using the Calculator

Tips: Enter the weight in pounds and all dimensions in inches. Ensure accurate measurements for proper freight classification.

5. Frequently Asked Questions (FAQ)

Q1: Why is 1728 used in the formula?
A: 1728 is the number of cubic inches in a cubic foot (12 in × 12 in × 12 in = 1728 in³/ft³).

Q2: How does density relate to freight class?
A: Generally, higher density means lower freight class (better rates). For example: >50 lb/ft³ = Class 50, 30-35 lb/ft³ = Class 70, etc.

Q3: What if my shipment has multiple pieces?
A: Calculate total weight and combine dimensions as if all pieces were in one large box, or calculate density for each piece separately.

Q4: Does this account for pallet weight?
A: No, pallet weight should be included in the total weight if you're measuring the entire palletized shipment.

Q5: How accurate does this need to be?
A: Very accurate - freight class disputes can lead to reclassification and additional charges. Measure to the nearest inch and pound.
