What is the function of air waybill?

1. The air waybill functions as a contract, because according to relevant regulations, the air waybill itself is a cargo transportation contract signed between the shipper and the air carrier, and the contract automatically expires after the goods arrive at the destination and are handed over to the consignee.

2. Receipt receipt for air cargo. The air waybill is a receipt issued by the carrier after receiving the goods, proving that the goods have been received intact.

3. The air waybill also functions as a freight bill. Because the air waybill lists various charges and amounts, it can be used as a bill and reimbursement. Usually the carrier will also use the "carrier's copy" in the air waybill as an accounting voucher.

4. The air waybill serves as a customs reimbursement voucher. Because air cargo needs to undergo import customs declaration after arriving at the destination airport, the air waybill is often one of the basic documents for customs release during the customs declaration process. Therefore, the air waybill is also a customs declaration document.
