What Do ETA and ETD Mean?
ETD (Estimated Time of Departure) is the date and time a vessel or aircraft is scheduled to leave the origin port or airport β for China sourcing, that means leaving a Chinese port such as Ningbo, Shanghai or Shenzhen (or an airport such as Guangzhou or Hong Kong). ETA (Estimated Time of Arrival) is the date and time it is scheduled to reach the destination port or airport. The two are linked: the carrier calculates the ETA by adding its published transit time to the ETD.
The confusion is that both read like a delivery date. Neither is. The ETD is a departure β your goods have not arrived anywhere yet β and the ETA is arrival at the port, not your warehouse. After the ETA, customs clearance, terminal handling and inland trucking still have to happen before the goods reach you.
ETA vs ETD: Side-by-Side Comparison
| Point | ETD (Estimated Time of Departure) | ETA (Estimated Time of Arrival) |
|---|---|---|
| Full name | Estimated Time of Departure | Estimated Time of Arrival |
| Refers to | Leaving the origin port / airport | Reaching the destination port / airport |
| Direction | Outbound from China | Inbound at destination |
| When it appears | At booking / shipping advice | At booking, updated after sailing |
| How it is derived | Carrier sailing schedule | ETD + carrier transit time |
| Is it the delivery date? | No (goods still in transit) | No (port arrival, not your door) |
| Typical accuracy | Β± a few days; can roll | Β± several days (congestion, weather) |
| Used for | Production & pickup cut-off planning | Restock, clearance and cash-flow planning |
A Real China Shipping Timeline
Here is a typical sea freight China β US West Coast timeline for a 1,000-unit order, showing where ETD and ETA sit in the sequence:
| Stage | Typical Duration | Milestone |
|---|---|---|
| Booking confirmed & container assigned | 3β7 days after order | Booking dated |
| Factory pickup & loading at origin | 1β3 days | Container gate-in |
| Vessel departs China | Sailing date | ETD |
| Ocean transit | 18β30 days | In transit |
| Vessel arrives at destination port | Arrival date | ETA |
| Customs clearance & terminal handling | 3β5 days | Released |
| Inland delivery to warehouse | 2β4 days | Delivered |
So for a sea shipment: booking β ETD β 7β14 days, and ETA β delivered β 5β9 days. By air freight the same order is much faster: ETD β 2β5 days after booking, transit 3β7 days, and destination clearance plus delivery 2β4 days.
How to Use ETA and ETD to Plan a Restock
- Plan production off the ETD. Work backwards from the ETD to set your factory completion and pickup dates; if the ETD rolls, everything upstream shifts.
- Plan landing and cash flow off the ETA. The ETA is when duty and clearance fees become due (under DDU/DAP) or when the seller finalises the landed cost (under DDP).
- Convert ETA into a delivery date by adding destination clearance and inland trucking: roughly 3β7 days by sea, 2β4 days by air.
- Track weekly, not once. An ETA given at booking is a forecast; the reliable ETA arrives after the vessel passes its first transshipment port.
- Add a buffer for deadlines. For FBA windows and retail launch dates, use ETA + 7β14 days as your working date.
How Yeatru Reports ETA and ETD
Yeatru shares both dates on every shipment so you can plan with confidence:
- ETD and confirmed on-board date from the carrier once the container leaves China.
- Updated ETA after each transshipment, plus a realistic delivery estimate that folds in destination clearance and inland trucking.
- Weekly tracking so a rolled sailing is flagged early, before it breaks your restock plan.
Frequently Asked Questions
1. What is the difference between ETA and ETD?
ETD (Estimated Time of Departure) is when the vessel or aircraft is scheduled to leave the origin port in China. ETA (Estimated Time of Arrival) is when it is scheduled to arrive at the destination port. ETD comes first; ETA is the ETD plus the transit time.
2. What does ETD mean in shipping?
ETD stands for Estimated Time of Departure: the planned date and time a container vessel or aircraft departs the origin port or airport. It is the date your goods leave China, and it is an estimate that can change if the sailing is rolled or delayed.
3. What does ETA mean in shipping?
ETA stands for Estimated Time of Arrival: the planned date and time the vessel or aircraft arrives at the destination port or airport. It is not the date the goods reach your warehouse, because customs clearance and inland delivery still have to happen after arrival.
4. Is the ETA the same as the delivery date?
No. The ETA is arrival at the destination port or airport. After that the goods still need customs clearance, terminal handling and inland trucking. Add roughly 3β7 days by sea and 2β4 days by air to turn an ETA into an expected delivery date.
5. Why does my ETD keep changing?
An ETD is an estimate. Carriers roll bookings when a vessel is overbooked, blank sailings are announced, or equipment is short. When the vessel actually departs, the carrier issues a confirmed on-board date and an updated ETA. Always re-check the ETA after sailing.
6. How accurate are ETA and ETD estimates from China?
ETD is usually accurate within a few days once the vessel has sailed. ETA can shift by several days due to port congestion, weather or transshipment. For planning, treat the ETA as a target and add a 7β14 day buffer for critical deadlines.
Conclusion
ETA and ETD look similar but answer opposite questions: ETD is when your goods leave China; ETA is when they arrive at the destination port. Neither is your delivery date β the goods still need clearance and inland trucking after the ETA. Plan production off the ETD, plan restock and cash flow off the ETA, confirm both after the vessel sails, and keep a 7β14 day buffer for deadlines.
