What Is the Difference Between ETD and ETA on a Shipment Plan?

Two abbreviations on a booking note carry the whole plan, and they are read as if they were one date with two ends. They are not. ETD is an estimate of a departure set by a carrier schedule; ETA is an estimate of an arrival at a port, which is a different place, measured from the same estimate, and it is not the date anything becomes sellable. This piece takes a shipment plan apart in the order it should be read, and names the three things that sit between the two dates.

What Is the Difference Between ETD and ETA?

ETD is the estimated time of departure of the vessel from the load port, and ETA is the estimated time of its arrival at the discharge port. The two are separated by a transit that the carrier operates, and each of them is an estimate rather than a commitment, which is what the E stands for and what buyers forget. A plan showing both is a plan with a transit implied between them.

The more useful way to hold them is as two different kinds of date. ETD is mostly within the control of the programme: the cartons have to reach the container yard before the cut-off and the documents have to be right before their cut-off. ETA is mostly outside it: once the vessel sails, the arrival belongs to the carrier, the lane and the weather. Pressure works on one and not on the other.

Read the third and fourth rows together and the asymmetry appears: the ETD is a date the programme can influence until the cartons are in the yard, and the ETA is a date it can only observe. That is the practical reason a delivery promise should be written to the ETD under FOB terms rather than to an arrival nobody is operating.

What Does ETD Measure, and From Where?

The departure of the named vessel from the named load port, and both halves of that sentence matter. A plan that names the port and not the vessel is a plan with a schedule someone else can substitute; a plan that names the vessel and not the port is worse, because the same vessel calls at more than one. Under Incoterm decision tool terms agreed as FOB Xiamen, the ETD at Xiamen is where the obligation ends.

The date is also an estimate against a service rather than against a booking. A direct service and a service with one transshipment can carry the same ETD and an ETA a week apart, and the difference is invisible on a plan that shows only the two ends. Ask for the service and any transshipment port with the two dates, because that is where the planning number actually lives.

Where Do the Cut-Offs Sit Between ETD and ETA?

Both of them before the ETD, and both of them are fixed times rather than targets. The container yard cut-off is the moment the terminal stops receiving for that sailing, and a carton that arrives after it rolls to the next vessel regardless of how well the rest of the run went. The document cut-off is earlier still, and it is the moment after which a correction to the bill of lading costs a sailing rather than an email.

The practical rule is to work backwards from the ETD and treat both cut-offs as the real deadlines. An ETD of the twentieth means cartons in the yard by the seventeenth and the document set lodged before that, and a production plan that finishes on the nineteenth has missed the vessel while appearing to have met the date. That arithmetic is the single most common cause of goods that were finished on time and shipped late.

What Is the Difference Between ETD and ATD?

One letter, and it is the difference between an estimate and a fact. ATD is the actual time of departure, recorded after the vessel has sailed, and ATA is the actual arrival. They are not planning figures; they are the record of what happened, and they are what a claim, an insurance question or a dispute about a delivery obligation is settled on.

The reason to ask for them is that the record is what the estimate is measured against. A carrier whose ETD and ATD differ by four days on four consecutive sailings is a carrier whose ETD should be planned around with four days added, and that is information no schedule will volunteer. Two columns in a log, one estimated and one actual, and the lane reveals itself within a quarter.

What Does Transit Include, and What Does It Not?

Transit is the movement of the container from the load port to the discharge port, and it includes the water leg, any transshipment and the discharge. It does not include the inland haulage to the terminal before it, the customs entry after it, or the inland delivery and receiving at the far end. Those three are separate operations with separate owners, and they are the three most often folded into a transit figure that was never meant to carry them.

The safest way to hold it is to ask for the transit in writing for the lane and the service, and then to add each of the three separately with the party who owns it named. The question to ask a forwarder is not how long it takes but what the figure covers, and the answer to that question is usually where the missing week is hiding.

The last two rows are the ones a production-side calendar never carries and a buyer-side calendar always needs. A container can be discharged on the first and still not be receivable until the sixth, and the five days in between belong to the receiving warehouse rather than to anybody in the production programme. Planning them is the difference between an arrival date and a selling date.

What Does ETA Promise at the Destination?

Very little, and less than buyers assume. It is an estimate of the vessel arriving at a port, not of the container being available, and the container sits behind discharge, release and entry before it can be collected. An ETA of the tenth is an ETA of the tenth, and the goods are frequently collectable on the fourteenth.

It also says nothing about the condition of the goods. The ETA is a transport date, and the inspection that decided whether the lot was acceptable happened at the origin, five steps earlier. A buyer who reads the ETA as the date the goods become sellable is reading two things at once, and both halves of the reading are wrong.

How Do You Turn a Shipment Plan Into a Warehouse Date?

By adding the six steps in the order of the table and dating each one. Start at the inspection, add the reserve, add the haulage to the yard, add the wait to the ETD, add the transit the forwarder confirmed, add the entry, and add the receiving appointment. The result is a date the warehouse can be booked against, and it is usually a week later than the ETA alone suggested.

Then book the receiving appointment against that date rather than against the ETA. A warehouse appointment booked for the day the vessel arrives is an appointment that will be missed, and a missed appointment is a container sitting on the terminal accruing charges while the goods are technically in the country. There is no other step in the plan where a five-minute action saves that much.

What Moves an ETD After It Has Been Given?

Three things, in descending order of frequency: the vessel slips on its previous call, the booking is rolled because the container missed the cut-off, and the sailing is cancelled or the service omits the port. None of the three is caused by anything happening on the production floor, which is why a rolled booking is so often reported as a production delay when it is not one.

The response is the same in all three cases and it is worth having ready. Ask for the next available ETD, in writing, with the cut-off that belongs to it, and then recompute the warehouse date rather than the arrival date. A rolled vessel changes every downstream date by the same number of days, and the party who recomputes first is the party who rebooks the appointment before it is missed.

What Should a Shipment Plan Say in Writing?

Document cut-off

The last moment the document set can be corrected

Container yard cut-off

The last moment cartons are received for the sailing

Vessel and load port

Both named, not one of them

ETD

The estimated departure, at the named port

Service and transit

The lane, the service and any transshipment port

ETA

The estimated arrival at the named discharge port

Receiving calendar

The appointment date booked at the destination

Seven fields and a shipment plan becomes a schedule somebody can be held to rather than two abbreviations. We do not promise the fastest 20 days. We promise a delivery date you can calculate. The arrival is the fourth step of six, and a plan that stops at the fourth is a plan that has not finished.

How Do You Read a Carrier Schedule?

As a service with a rotation rather than as a line with two dates on it. A service calls at a sequence of ports on a published rotation, and the same vessel appears on several lanes in the same month with different cut-offs at each. The two things worth holding are the rotation and the transit between the pair of ports the plan depends on, and both of them arrive in a single email from a forwarder if they are asked for.

The second thing to read is whether the transit is direct or routed. A direct service and one with a transshipment can differ by a week between the same two ports, and the routed option carries a second set of cut-offs at the port where the container changes vessel. Where both are offered it is a genuine trade rather than a formality: the direct service is faster and usually costs more, and the routed one is slower and usually costs less.

What Should the Log Record?

Two columns per shipment: the estimate and what actually happened. The ETD beside the ATD, the ETA beside the ATA, and the receiving date beside both. Four sailings are enough for the pattern to appear, and the pattern is what a planner needs, because a lane that arrives three days late three times out of four is a lane that should be planned three days late.

The log also answers the question that follows every late delivery, which is whether this one was unusual. Without it the answer is an impression, and impressions in this area are reliably favourable to whichever side is doing the speaking. With six entries in two columns the answer is a number, and the number is the same for both parties, which is the only property that matters in the conversation.

One thing a shipment plan cannot tell a buyer is whether the goods inside the container were inspected. The booking note carries dates, a vessel and a container number, and it says nothing about the AQL 2.5 draw that released the cartons. That evidence sits in the production file, and the two documents belong together in one folder, because a container that arrived on time and was never inspected is one whose arrival is the only fact known about it.
