ATA (Actual Time of Arrival)

Actual Time of Arrival (ATA) refers to the specific time when a ship, aircraft, or cargo actually arrives at the destination port or place. It is a key time node in international trade and logistics. It is commonly used to determine delivery time, calculate demurrage/despatch, judge whether the shipment period or arrival period under a letter of credit has been violated, and serve as the basis for the commencement and termination of insurance liability. Unlike Estimated Time of Arrival (ETA), ATA is an objective fact that has already occurred, while ETA is an estimated time. It also differs from 'time of completion of discharge': ATA only indicates arrival and does not include subsequent operations such as berthing and unloading. When using ATA, note the following: 1) Different carriers may define 'arrival' as anchorage, berth, or pilot station, so it should be clearly specified in the contract; 2) ATA is usually based on carrier or port authority records, and it is advisable to keep evidence such as arrival notices and deck logs; 3) In letter of credit transactions, if 'arrival no later than a certain date' is required, ATA is the basis for judgment, but attention should be paid to whether the bank accepts such soft clauses. In short, ATA is an important time proof linking transportation and trade settlement.
