Air freight chargeable weight explained (with Pakistani examples)

Airlines charge for space, not just weight

An aircraft hold fills up by volume long before it fills up by weight. That is why every airline quotes on chargeable weight: the higher of your actual gross weight and your volumetric weight.

For general air cargo the volumetric formula is length x width x height in centimetres, divided by 6000. The result is kilograms. Compare it to the scale weight and the larger number is what you pay for.

• Gross weight: what the scale reads, including packaging and pallets
• Volumetric weight: (L x W x H in cm) / 6000 per piece
• Chargeable weight: the higher of the two, rounded up to the next 0.5 kg

A worked example from Sialkot

A Sialkot exporter ships 12 cartons of leather gloves, each 60 x 40 x 50 cm and 15 kg. Gross weight is 180 kg. Volumetric weight is (60 x 40 x 50) / 6000 = 20 kg per carton, or 240 kg total. The airline bills 240 kg.

Now take surgical instruments in the same lane: 8 cartons at 40 x 30 x 25 cm and 22 kg each. Gross is 176 kg, volumetric is only 40 kg. Dense cargo pays on actual weight, which is why instruments air freight far more economically than gloves or textiles.

Four ways to cut chargeable weight

Most of the savings we find for clients come from packaging and consolidation decisions made before the cargo leaves the factory.

• Right-size cartons — 5 cm of dead air on every side can add 15% to volumetric weight
• Compress and vacuum-pack soft goods such as garments, gloves and bags
• Mix dense and light cargo in the same consolidation so the average density improves
• Palletise to airline ULD dimensions instead of building irregular stacks

When air still wins on total cost

Chargeable weight is only one line on the landed cost sheet. Air freight from Pakistan reaches Europe in three to five days versus 25 to 35 days by sea, which frees working capital, avoids air-charter rescues before trade shows, and keeps you out of stockout penalties with retail buyers.

For high-value, low-volume cargo the freight premium is often smaller than the inventory carrying cost it removes.
