Introduction to Chargeable Weight

Chargeable weight is a fundamental concept in the shipping and freight industry. It serves as the foundation for determining the costs associated with transporting goods, whether by air, sea, or land. In essence, chargeable weight isn’t solely about the actual weight of an item but may consider its volume too, especially if the item is bulky yet lightweight.

How is Chargeable Weight Calculated?

Weight vs. Volume

There are two main components to consider: the actual weight of the shipment and its volumetric or dimensional weight. Typically, carriers will charge based on whichever is greater.

Volumetric Calculation

To determine the volumetric weight of a package, the following formula applies:

Volumetric Weight=Length×Width×HeightDivisor\text{Volumetric Weight} = \frac{\text{Length} \times \text{Width} \times \text{Height}}{\text{Divisor}}


  • LengthWidth, and Height are the dimensions of the package (typically in centimeters or inches).
  • Divisor is a constant number provided by the shipping carrier. For air freight, common divisors include 5,000 for cm³/kg or 166 for in³/lb, though this can vary by carrier and region. 


For instance, a box that measures 50cm x 50cm x 50cm has a volumetric weight of 25kg when using the 5,000 cm/kg factor.

It’s worth noting that the divisor is based on the density of the shipment and is set by the individual shipping company or governing body to ensure the effective utilization of cargo space. Always consult with the specific carrier or with your freight forwader to understand their volumetric weight calculation and divisor. 

Comparing Weights

Once the actual and volumetric weights are determined, the greater of the two is considered the chargeable weight.

Importance of Chargeable Weight in Shipping Costs

Fairness in Pricing

The concept ensures fairness. For example, shipping a large box of feathers may occupy the same space as a small but dense package of lead. Even though the feathers are light, they take up valuable space, and that’s taken into account with chargeable weight.

Resource Optimization

It helps shipping companies optimize their resources, ensuring they’re compensated appropriately for space and weight constraints.

 Tips for Businesses

Efficient Packaging

Businesses can reduce shipping costs by utilizing efficient packaging. By minimizing wasted space within boxes and selecting packaging dimensions closely aligned to the product’s size, companies can often reduce the volumetric weight.

Multi-modal Transportation

Sometimes, the mode of transport can affect the chargeable weight calculation. Businesses might benefit from exploring multi-modal transportation options to find the most cost-effective solution.
