How Shipping Costs Are Calculated (Weight vs Volume)
Carriers charge on the greater of actual weight or volumetric weight (size). Air freight uses a volumetric divisor, while sea freight is priced mostly by volume in cubic meters. Bulky-but-light cargo is billed on size, not scale weight.
Here is a puzzle many importers hit. You ship a box of pillows that weighs almost nothing, yet the bill is high. Why? The answer is volumetric weight. Let us make it simple.
Actual weight vs volumetric weight
Carriers care about two numbers. One is the real weight on the scale. The other is the space the cargo takes up, called volumetric weight. They charge you on whichever is larger.
That is why bulky-but-light goods cost more than you expect. They fill space even if they are not heavy.
How each mode prices it
- Air freight β uses a formula that turns box size into a weight, then bills the higher number.
- Sea freight (LCL) β priced mostly by volume, in cubic meters.
- Sea freight (FCL) β a flat price for the whole container, so filling it well saves money.

How to lower your cost
Smart packing helps. Smaller, tighter boxes cut volumetric weight. Choosing the right sea or air option for your cargo shape matters too. We measure both numbers and quote the real price, with no hidden charges.
Frequently asked questions
What is volumetric weight?
It is a weight worked out from the size of your cargo. Carriers bill the higher of this and the real weight.
Why did my light box cost so much?
Because it was bulky. Big, light cargo is charged on the space it fills.
How can I reduce shipping cost?
Pack tightly, pick the right mode, and combine orders. We help with all three.
