1、 Valuation　Charges　　

Similar to the carrier of sea or railway transportation, the air carrier also requires to limit its liability to the cargo within a certain range to limit the operational risk.

The Warsaw Convention stipulates the maximum liability limit for the loss, damage or delay of goods caused by the carrier's own negligence or intent. This amount is generally understood as 20 dollars per kilogram or 9.07 pounds per pound or other equivalent currencies. If the value of the goods exceeds the above value, it will increase the carrier's responsibility, and the carrier will charge the declared value fee. Otherwise, even if there are more losses, the carrier will not be liable for the excess.

The declared value of the goods is for the whole goods, and it is not allowed to declare the value of a part of the goods. The stated value charge is based on the actual gross weight of the goods, and the calculation formula is:

Declared value fee = (value of goods - gross weight of goods × 20 dollars / kg) × Declared value fee rate

The rate of declared value fee is usually 0.5%. Most airlines also stipulate the minimum charging standard of declared value fee while stipulating the declared value rate. If the declared value fee calculated according to the above formula is lower than the minimum standard of the airline, the shipper shall pay the declared value fee according to the minimum standard of the airline.

2、 Other surcharges

Other surcharges include voucher preparation fee, cash on delivery surcharge, pick-up fee, etc., which are generally charged only when the carrier or air freight forwarder or centralized shipper provides services.
