Gross Weight vs Volumetric Weight vs Chargeable Weight
Air freight pricing uses several weight terms. Understanding the difference helps avoid quote confusion before cargo is booked.
Simple definition
Gross weight is the actual physical weight of the cargo, including packaging. Volumetric weight is the space-based weight calculated from cargo dimensions. Chargeable weight is the weight used for pricing, usually whichever is higher between gross weight and volumetric weight.
In air freight, the airline is selling both weight capacity and aircraft space. That is why bulky cargo can be charged higher than its actual scale weight.
Comparison table
| Term | Meaning | Used for pricing? |
|---|---|---|
| Gross weight | Actual weight measured on a scale | Yes, if higher than volumetric weight |
| Volumetric weight | Dimension-based weight | Yes, if higher than gross weight |
| Chargeable weight | The final billing weight | Yes |
Simple example
Suppose one carton weighs 40 kg. Its size is 80 × 70 × 60 cm. Using a common air freight divisor of 6,000, the volumetric weight is:
80 × 70 × 60 ÷ 6,000 = 56 kg
The gross weight is 40 kg, but the volumetric weight is 56 kg. In this case, the chargeable weight is 56 kg.
Common mistake
A common mistake is sending only gross weight when requesting an air freight quotation. If the dimensions are missing, the first estimate may be too low. Once the warehouse measures the cargo, the chargeable weight can increase.
Why it matters for Indonesia shipments
For cargo moving to or from Indonesia, accurate dimensions are important before booking space, arranging pickup, preparing quotation, and estimating arrival-side charges at CGK or other airports.
When to ask a freight forwarder
- You have bulky cartons but the weight is light.
- You are comparing different packing options.
- The supplier only gave gross weight, not dimensions.
- You need a clearer estimate before shipping to or from Indonesia.
How Ambara can help
Ambara can review your gross weight, carton dimensions, number of packages, origin, destination, and service scope before quoting.
FAQ
Is chargeable weight always higher than gross weight?
Not always. If gross weight is higher than volumetric weight, gross weight becomes the chargeable weight.
Why do airlines use volumetric weight?
Because aircraft space is limited. Light but large cargo still takes up valuable space.
Can better packing reduce chargeable weight?
Yes. More compact packing can reduce volumetric weight, as long as the cargo remains safe and compliant.
