ETA (Estimated Time of Arrival): Estimated time of arrival
ETA refers to the time when the cargo, ship or aircraft is expected to arrive at the destination. This time is usually calculated by the transport company based on factors such as the speed of the transport tool, route and weather conditions, and is a key node in the logistics plan.
For example: Shipping from China to Kuwait, the goods departed from Shenzhen on December 23 and are expected to arrive at Kuwait Airport on December 28, so the ETA is December 28.
The role of ETA:
- Provide a reference for logistics planning: ETA allows the consignee to arrange unloading, customs clearance and warehousing in advance to ensure the smooth operation of the entire supply chain.
- Improve customer experience: Through transparent estimated arrival time, customers can keep track of the status of the goods at any time, thereby improving their satisfaction with logistics services.
- Optimize resource allocation: For hubs such as ports and airports, ETA can help plan the use of resources, such as loading and unloading equipment, labor and storage space.
Issues to note:
ETA is only an estimate and may be affected by various factors such as weather and route congestion, so deviations may occur.
For goods with multiple transport segments, ETA needs to comprehensively consider the connection time of each transport segment.
ETD (Estimated Time of Departure): Estimated time of departure
ETD refers to the time when the goods or means of transport are expected to depart from the place of origin, usually provided by the copyright when the goods are loaded or the transportation plan is determined. It is the starting point of logistics operations and the starting benchmark of the time node.
Example: Shipping from China to Oman, if the ship departs from Ningbo on December 22, the ETD is December 22.
Importance of ETD:
- Starting point of transportation plan: ETD determines the timeline of the goods in the entire logistics link, which helps to formulate subsequent transportation and arrival plans.
- Coordinate multi-party cooperation: In international logistics, the accuracy of ETD directly affects the collaboration between upstream and downstream of the supply chain, such as warehouse arrangements, cargo preparation, etc.
- Control transportation costs: Reasonable arrangement of ETD can avoid the generation of port detention or delay fees, thereby effectively reducing logistics costs.
Issues to note:
ETD may change due to cargo loading, customs inspection or weather conditions, and needs to be updated in real time to maintain the accuracy of the transportation plan.
For cross-border logistics, changes in ETD may lead to adjustments in subsequent customs clearance and distribution schedules.
ATD (Actual Time of Departure): actual departure time
ATD refers to the time when the goods or means of transportation actually leave the port of departure. This time is usually recorded on the shipping document and is used to confirm the actual start time of the shipment.
For example: Shipping from China to Iran, it was originally planned to leave Shanghai Port on December 20, but due to delays due to the peak season, the ship will sail on December 25, and the ATD at this time will be changed to December 25.
The role of ATD:
- Reflect the actual situation of transportation: ATD can be used to evaluate the implementation of the transportation plan. Especially when there are differences between ETD and ATD, the reasons can be analyzed and follow-up plans can be adjusted.
- Generate transportation reports: ATD is an important parameter in logistics reports and transportation history data, helping companies optimize transportation efficiency.
- Calculate transportation timeliness: By comparing ATD and ETA, companies can evaluate whether there are delays in the transportation process and take necessary measures to improve it.
Issues to note:
ATD may deviate significantly from ETD due to port congestion, weather changes, etc., and needs to be communicated with customers in a timely manner.
In some cases, such as goods transported in multiple stages, the ATD of each stage needs to be recorded separately.
ATA (Actual Time of Arrival): Actual arrival time
ATA refers to the time when the goods or transport vehicle actually arrives at the destination, in contrast to ETA. ATA is an important sign of the completion of cargo transportation and an important evaluation standard for the quality of logistics services.
Example: Shipping from China to Iraq was originally scheduled to arrive at the port of Iraq on January 15, but due to congestion at the terminal, the cargo ship did not arrive until January 20. The ATA of this batch of goods is January 20.
The significance of ATA:
- Confirmation of delivery completion: ATA marks the end of the transportation link, and the handover of goods from the copyright to the consignee is officially completed.
- Measure transportation efficiency: By comparing ETA and ATA, the accuracy and execution efficiency of the transportation plan can be analyzed, thereby improving future transportation processes.
- Support bill settlement: ATA is usually one of the important bases for calculating transportation service fees, especially in time-sensitive transportation.
Issues to note:
If the difference between ATA and ETA is large, it may be necessary to re-evaluate the problems in the transportation link, such as whether there is a transportation vehicle failure, weather impact, etc.
For special goods such as cold chain transportation, ATA time deviation may directly affect the quality of the goods and requires special attention.
