DDU air transport terms include all costs in each link, many of which have minimum consumption and fixed costs calculated by ticket. From the perspective of the demander, all costs need to be considered.

It is more advantageous to choose DDU air transport for the following three weight segments and cargo volume types:

1. Heavy goods are more than 100Kg
If it is less than about 100Kg, the total cost of international express may be lower, and if it is more than about 100Kg, it is more cost-effective to choose DDU air freight.

2. When the volume of the foamed goods is greater than about 0.5 square meters
The express billing weight is the gross weight and the volume weight, whichever is greater, and the air freight billing weight is the gross weight and the volume weight, whichever is greater, and the ratios by which the two volume weights are multiplied are different. , When the volume of the foam is 0.5 square meters, the weight is 0. 5m3*200=100Kg, and DDU air freight can be considered instead of express.

3. When the weight is greater than 300Kg
At present, some special lines on the market have lower costs than international express, but when the goods are larger than 300Kg, the total cost of DDU air freight is generally less than that of special lines.
