Air freight is an indispensable option, especially for time-sensitive shipments. However, several factors affect the cost of your shipment, and one of them is the concept of chargeable weight. So, how is the chargeable weight calculated in air cargo, and why is it important? In this article, we will discuss this topic in detail.

What is Chargeable Weight?

Chargeable weight is the weight used by airlines to calculate the freight charges for air cargo. This weight is determined by comparing the actual gross weight of the shipment with its volumetric weight (dimensional weight), and the higher of these two values is considered the chargeable weight.

Why is There Such a Thing as Volumetric Weight?

Aircraft cargo holds have both weight and volume limitations. A light but bulky shipment can take up more space in the aircraft's cargo hold than its actual weight would suggest, potentially preventing other shipments from being transported. Therefore, airlines calculate volumetric weight to factor in the space occupied by the shipment into the cost.

How is Volumetric Weight Calculated?

Volumetric weight is usually calculated using the following formulas. However, keep in mind that there might be slight differences between different airlines and regions:

• Metric System: (Length (cm) x Width (cm) x Height (cm)) / 6000
• Imperial System: (Length (inches) x Width (inches) x Height (inches)) / 166

The result obtained from these formulas is in kilograms (kg).

How is Chargeable Weight Determined?

1. Determine the actual gross weight of your shipment (the weight obtained by weighing it).
2. Measure the dimensions of your shipment (length, width, height).
3. Calculate the volumetric weight of your shipment using the formula above.
4. Compare the actual gross weight with the volumetric weight.
5. The higher of these two values is considered the chargeable weight of your shipment.

Example Calculation:

Let's say you have a box with dimensions of 50 cm x 40 cm x 30 cm and an actual weight of 8 kg.

1. Actual Weight: 8 kg
2. Volumetric Weight: (50 cm x 40 cm x 30 cm) / 6000 = 60000 / 6000 = 10 kg

In this example, the volumetric weight (10 kg) is higher than the actual weight (8 kg), so the chargeable weight of your shipment will be 10 kg.

Conclusion:

Understanding the chargeable weight calculation is crucial for accurately estimating the cost of air freight. By optimizing the dimensions of your shipment and paying attention to your packaging, you can potentially reduce your transportation costs. Considering these factors when preparing your shipment will help you avoid unexpected expenses.
