Chargeable Weight

Definition

Chargeable Weight is the weight basis upon which a carrier calculates the final freight cost for your shipment. It is determined by comparing the physical weight of the cargo against the space it occupies.

Core Process: How Chargeable Weight is Determined

The carrying capacity of every vessel is ultimately limited by weight or volume. The Chargeable Weight model ensures the carrier charges based on whichever constraint is met first.

• The carrier measures the Gross Weight (the actual weight of the product, packaging, and pallet), also known as Actual Weight.

• The carrier also measures the Volumetric Weight (the equivalent weight calculated from the shipment’s volume).

• The Chargeable Weight is whichever of these two figures is greater.

If a shipment is dense (heavy for its size), the Gross Weight will likely be used. If a shipment is light and bulky (for example, packaging materials or foam), the Volumetric Weight will be used, often resulting in a higher cost than expected based only on physical weight.

Volumetric Weight Overview

Volumetric weight converts the volume (cubic dimensions) of a package into a weight equivalent. The calculation formula varies depending on the mode of transport and sometimes by the trade lane.

• The typical formula is: (Length x Width x Height) / Divisor.

• For air freight, a common divisor is 6000 (metric), making volumetric weight a frequent determinant of chargeable weight due to the space constraints in aircraft.

Expert Advice: Estimating Chargeable Weight

The best way to manage costs is to ensure that the information provided in your initial quote request is as accurate as possible.

• Accurate Quote Requests: The actual weight provided for the initial quote is the Gross Weight. This number must be precise.

• Account for Palletization: A common cause of discrepancies is the addition of pallet dimensions and associated packaging after the initial estimate. Always confirm if the dimensions provided include palletization.

• Invoice Verification: The final chargeable weight is the figure that appears on your freight invoice and on supporting documentation like the Airway Bill. This number is what the carrier billed you to move your shipment.
