# Air Freight Charge Calculation for Garments Import-Export

2017-08-29

Introduction: Normally freight charge under air shipment of garments is totally depends on both gross weight or actual weight and cargo weight. If the gross weight or actual weight is higher than cargo weight, then freight charge is fixed on the basis of gross weight. Again, if cargo weight is higher than gross weight, then freight charge is fixed on the basis of cargo weight. That means, among two weights, gross weight and cargo weight, which one will be higher, freight charge will be fixed on that.

Chargeable weight is an equilibrium point, where actual weight and cargo weight are totally balanced. But there is an important reason that why freight charge under air shipment is totally depends on both gross weight or actual weight and cargo weight.

One example is enough to remove the confusion about it.

Suppose, you are exporting 500kg of cotton and another one is exporting 500kg of iron under air shipment. Your exported cotton needed more space than iron, but weight is the same. In this case, if air freight is charged on the basis of space then you will have to pay more amount than iron exporting person. As a result, actual weight or gross weight and cargo weight both are in consideration during freight charge calculation, which one is higher, that is chosen for freight charge.

So, chargeable weight calculation system in air freight is discussed in the following:

At first you have to find the cargo measurements with length, width and height. Then calculate the CBM of cargo by using following formula-

CBM calculation for cargo= Length (m) ×weight (m) × height (m)

Aftercalculating CBM of cargo, it’s divided by 0.006. This result is termed as cargo weight. Now, cargo weight is compared to the gross weight or actual weight. Which one is higher, will be considered as a chargeable weight.

Now two examples here to remove all confusions about the above explanation.

Example-01:

Suppose,

Gross weight or actual weight is 200kg,

Cargo length is 100cm = 1m,

Cargo width is 100cm = 1m,

Cargo height is 100cm = 1m.

Find out the chargeable weight for air freight of this shipment.

Solution:

Now, We calculate the Cargo CBM= Length (m) ×weight (m) × height (m)

= (1 × 1 × 1) m3

= 1m3

Now, cargo CBM has to divide by 0.006,

Cargo weight= Cargo CBM (m3)/ 0.006

= 1/ 0.006

= 166.67kg.

So, the gross weight or actual weight is 200kg and cargo weight is 166.67kg. Among two weights, gross weight or actual weight is higher than cargo weight. As a result gross weight or actual weight will be chosen for chargeable weight for this shipment.

Example-02:

Suppose,

Gross weight or actual weight is 140kg,

Cargo length is 98cm = 0.98m,

Cargo width is 95cm = 0.95m,

Cargo height is 96cm = 0.96m.

Find out the chargeable weight for air freight of this shipment.

Solution:

Now,

We calculate the Cargo CBM= Length (m) ×weight (m) × height (m)

= (0.98 × 0.95 × 0.96) m3

= 0.89376 m3

Now, cargo CBM has to divide by 0.006,

Cargo weight= Cargo CBM (m3)/ 0.006

= 0.89376/ 0.006

= 148.96kg.

In this shipment, the gross weight or actual weight is 140kg and cargo weight is 148.96kg. Among two weights, cargo weight is higher than gross weight or actual weight. As a result, cargo weight will be chosen for chargeable weight for this shipment.
