Calculate Chargeable Weight

Freight forwarder companies opt to calculate freight costs based on chargeable weight rather than the cargo’s gross or volumetric weight due to several practical considerations.

Firstly, chargeable weight ensures a fair and balanced approach to pricing, taking into account both the weight and volume of the cargo.

While gross weight solely focuses on the actual weight of the goods and volumetric weight considers the space they occupy, chargeable weight accounts for whichever is higher between the two.

This approach ensures that freight forwarders are adequately compensated for the resources required to transport the goods, whether it be fuel consumption, handling efforts, or space utilization.

Secondly, chargeable weight reflects the economic reality of shipping operations. Freight forwarders incur expenses based on various factors, including the weight and volume of the cargo.

By using chargeable weight, they can more accurately allocate costs to cover expenses such as fuel, handling fees, and space utilization, leading to a more transparent and efficient pricing structure.

In scenarios where goods vary significantly in weight and volume, such as shipments of heavy but compact items versus light but bulky ones, charging based on volumetric weight alone would not accurately reflect the resources required for transportation.

For instance, a shipment of steel may weigh more but occupy less space compared to a shipment of cotton, which may be lighter but voluminous.

Chargeable weight ensures that both aspects are appropriately considered, leading to fairer pricing and better resource allocation in the logistics industry.

Overall, the use of chargeable weight allows freight forwarder companies to accurately assess the costs associated with transporting goods, leading to more equitable pricing and efficient operations in the global supply chain.

What is the calculation formula for Chargeable Weight?

For those of you who simply want the formulas without a detailed explanation, here we go:

 

Gross Weight VS Volumetric Weight

In the realm of international logistics, distinguishing between lightweight and heavyweight goods is crucial for efficient and cost-effective transportation.

To comprehend these distinctions, one must first grasp the concepts of gross weight, volumetric weight, and chargeable weight.

Gross weight simply refers to the actual weight of a shipment, measured in kilograms or pounds.

It is the combined weight of the goods themselves along with any packaging or containers they are contained within.

Essentially, gross weight provides a straightforward measure of how heavy the cargo is in its entirety.

Volumetric weight, on the other hand, takes into account the space occupied by the shipment.

The calculation of volumetric weight is a straightforward process that significantly impacts your shipping strategy.
You simply take the package’s dimensions – length, width, and height – measured in either centimeters or inches, and multiply them together.
This figure is then divided by a carrier-specific volumetric conversion factor, which can differ based on the mode of transportation you choose.
This method ensures you can accurately predict shipping costs and optimize your logistics planning for better efficiency and cost savings.

Volumetric weight reflects the density of the cargo and helps determine the amount of space it will occupy during transit.

Now, chargeable weight serves as a pivotal factor in determining shipping costs. It is the higher value between the gross weight and the volumetric weight of the shipment.

In essence, chargeable weight ensures that freight costs are based on whichever aspect—weight or volume—will result in a higher fee, thereby ensuring fair compensation for the resources utilized in transportation.

As for lightweight and heavyweight goods, these terms refer to the relative characteristics of shipments within the context of gross weight, volumetric weight, and chargeable weight.

Lightweight goods typically have a lower gross weight compared to their volumetric weight, meaning they may occupy a relatively large volume compared to their actual mass. Conversely, heavyweight goods tend to have a higher gross weight in proportion to their volumetric weight, indicating they are dense and compact in nature.

In summary, the distinction between lightweight and heavyweight goods hinges on the interplay between gross weight, volumetric weight, and chargeable weight.

By understanding these concepts and how they influence shipping costs, logistics professionals can optimize transportation strategies and ensure the efficient movement of goods across borders and continents.

 

The Actual Weight:

In the domain of air cargo transportation, understanding the distinction between actual gross weight and volumetric weight is fundamental for accurate pricing and efficient logistics operations.

Actual weight, derived from direct weighing on a scale, encompasses both Gross Weight (G.W.) and Net Weight (N.W.).

Gross Weight represents the total weight of the shipment, including the goods themselves and any associated packaging or containers.

On the other hand, Net Weight refers specifically to the weight of the goods without the packaging.

Among these measures, actual gross weight is the most commonly used metric. However, in air cargo transportation, where space constraints are often a significant consideration, volumetric weight plays a crucial role.

Volumetric weight, or dimensional weight, is a calculated value based on the volume occupied by the shipment.

It is determined by multiplying the length, width, and height of the package and dividing the result by a volumetric conversion factor, which varies depending on the carrier’s specifications.

Volumetric weight provides insight into the space utilization efficiency of the cargo.

In air cargo logistics, the comparison between actual gross weight and calculated volumetric weight is pivotal.

The higher of the two values is typically utilized for pricing and charging purposes.

This practice ensures that the costs associated with air transportation accurately reflect the resources consumed, whether by weight or volume.

How does Express Freight calculate Chargeable Weight?

1 Standard package measurement method:

Calculating volumetric weight is an effortless yet crucial step in refining your shipping strategy.
Begin by measuring your package’s dimensions – length, width, and height – in your choice of centimeters or inches.
Multiply these numbers to obtain the package’s volume.
Next, divide this volume by the volumetric conversion factor provided by your chosen carrier, which may vary with each transportation method.
This easy-to-follow formula allows for precise shipping cost estimations, paving the way for enhanced logistical efficiency and strategic cost management.
Example :Volume Weight = (Length × Width × Height) / 5000 = (15 × 30 × 20) / 5000 = 1.8KG

2 Surface package measurement method:

In the world of shipping, changes in a package’s dimensions due to compression can impact volumetric weight calculations.

When a package is compressed, the calculation is based on the longest side of the package.

For instance, imagine sending a package via DHL with initial dimensions of 15cm, 30cm, and 20cm. After sealing and compression, the dimensions adjust to 18cm, 33cm, and 22cm, with 18cm as the longest side.

To calculate the volume weight in such cases:

Volume Weight = (Length × Width × Height) / 5000 = (18 × 33 × 22) / 5000 = 2.7 KG

If the actual weight of the package is 2KG, but the calculated volume weight is 2.7KG, the shipping cost will be based on the volume weight.

Consequently, DHL would bill the shipment at a weight of 3KG.

Understanding these nuances in volumetric weight calculations can help you optimize shipping costs and make informed decisions for your logistics strategy.

3 Irregular package measurement method:

When it comes to shipping irregular-shaped items, understanding how volume weight is calculated can make a significant difference, just like the example we see with UPS.

Imagine sending a uniquely shaped parcel through UPS with dimensions of 15cm, 40cm, and 25cm.

Calculating the volume weight: Volume Weight = (Length × Width × Height) / 5000 = (15 × 40 × 25) / 5000 = 3KG

If the actual weight is 2KG, but the volume weight calculated is 3KG, the shipping cost will reflect the volume weight, resulting in a charge for 3KG.

It’s important to remember that the dimensions listed on the box represent its inner size and don’t include the box material’s thickness.

When shipping, the outer dimensions are used to measure the package accurately.

By grasping these intricacies in volumetric weight calculations, you can optimize your shipping costs and ensure a smooth logistics process for your valuable items.
