ETD (Estimated Time of Departure)

Estimated Time of Departure (ETD) is a core term in foreign trade and logistics, referring to the date and time that the carrier (shipping company, airline, or freight forwarder) has pre-notified as the planned departure of the vessel or flight from the port of origin. It typically appears in booking confirmations, loading lists, bill of lading instructions, and shipment tracking, and is used to arrange production, trucking, customs clearance, and insurance. Usage scenarios include: the seller informing the buyer of the shipment plan, the freight forwarder updating the customer on the sailing schedule, and reference for the latest shipment date required by a letter of credit. Note: ETD is an estimated time and may change due to weather, port congestion, or schedule adjustments; the actual departure date is subject to the carrier's final confirmation. It is the counterpart of ETA (Estimated Time of Arrival) and differs from ATD (Actual Time of Departure), which is the actual departure time. Difference: ETD emphasizes planning, while ATD emphasizes fact; ETD may be earlier or later than ATD. Foreign trade practitioners should closely monitor changes in ETD and promptly notify relevant parties to avoid breach of contract or extra costs due to delays.
