ETD (Estimated Time of Departure)

ETD (Estimated Time of Departure) refers to the expected date when goods will depart from the port of loading or place of origin. It is a key time node in foreign trade transportation and documentation. It usually appears in booking confirmations, bills of lading, shipping notices, and letter of credit terms, and is used to coordinate production, trucking, customs declaration, and insurance. Use cases include: the seller notifying the buyer of cargo readiness progress, the buyer arranging payment or insurance, and the freight forwarder updating vessel schedules. Notes: ETD is an estimated time and may change due to weather, port congestion, or carrier adjustments; the actual departure date is subject to the On Board Date on the bill of lading. It is opposite to ETA (Estimated Time of Arrival): ETD focuses on departure, while ETA focuses on arrival. It differs from ATD (Actual Time of Departure): ETD is a planned value. In letter of credit transactions, if a shipment period is stipulated, ensure the actual departure is no later than the latest shipment date; otherwise, it may constitute a discrepancy. Therefore, in practice, ETD changes need to be tracked dynamically and communicated with all parties in a timely manner.
