What is Estimated Time of Departure (ETD)
In transportation flow, the Estimated Time of Departure (ETD) is the expected time when the vessel, vehicle, or aircraft will depart from the origin port. This term is usually used in goods transportation to provide the expected time schedule for departure from the origin port to consignee and Stakeholders.
ETD is particularly importance for arrangements and coordination. It can help consignees, carriers, and receivers in easier operation processes, and arrange the shipment of goods in advance.
It is calculated by considering several factors such as:
- Stock management optimization
- Arrangement of the follow up shipment process
- Delivery time of goods
Factors Affecting Estimated Time Of Departure (ETD)
- Congestion of the port
- Shipment delayed due to the poor weather condition
- Malfunction of ship machinery/ equipment
- Delays in paperwork processing or clearance procedures
- Labor strike
- Goods and production processes are not delivered on time
- Tight shipping space and the transportation peak season
Estimated Time of Departure (ETD) is an important piece of information in shipping, which allows the carrier to make other supply chain logistic arrangements prior to the shipment of the goods, as well as preventing losses due to delays in advance.
