What it means

Volumetric weight is a calculated “weight” that air carriers use to charge for cargo that is light but bulky, so a shipment of pillows does not pay the same as the same mass of steel. It is computed from the shipment’s volume using a standard divisor — commonly length × width × height (in cm) ÷ 6000, giving a figure in kilograms — and the airline charges on the higher of actual or volumetric weight. The concept matters because air freight between China and the GCC is routinely used for urgent or high-value goods, and low-density cargo can be billed at several times its actual weight. Understanding volumetric weight lets you compare air versus express versus sea freight on a true like-for-like basis.

Who pays / who bears risk

Who pays

Shipper pays air freight on chargeable weight, which uses volumetric weight.

Who bears risk

Not a risk term — a pricing basis.

Common misunderstanding

The divisor differs: air freight typically divides by 6000, express couriers by 5000.

Why it matters

Air freight bills on the higher of actual or volumetric weight, so bulky light cargo can cost far more than its physical weight suggests — know the divisor before quoting.

Example

A 40kg carton of electronics measuring 120×80×60cm has a volumetric weight of 120×80×60÷6000 = 96kg, so it is billed at 96kg.
