Container glossary
What does gate-out mean?
Gate-out is the event recorded when a container leaves the destination terminal on a truck or rail car after it has been discharged from the ship. It ends the container’s stay inside the port and starts the clock for returning the box empty.
What has to be cleared before a box can gate out
Three releases have to be in place. Customs must have cleared the cargo. The shipping line must have released it, which means the freight is paid and the bill of lading has been surrendered or replaced by a telex release or waybill. And the terminal must have its own charges settled; many also require the truck to hold an appointment.
With all of that done, the driver presents the pickup reference, the gate records the container number and the time, and the box leaves. The terminal reports the move to the line, which publishes it as gate-out.
Reading a gate-out on the tracker
Gate-out is the seventh of the eight events a tracker normally shows, after “discharged” and before the empty return. Between it and the return the tracker shows nothing at all: carriers publish terminal events, not positions on the road.
Allow for the feed. A container that physically left the port this morning can still read “discharged” tonight, because terminal events reach public trackers with a lag of 6–24 hours. The terminal’s own website is usually ahead of the line’s page for this last stretch. The same word can also appear at the very start of a journey: a “gate-out empty” at origin is the shipper collecting the empty box from the depot.
Gate-out is not delivery
People read gate-out as “delivered”. It says only that the box has left the port on somebody’s truck. The warehouse may be an hour away or several days away by rail, and no tracker will show that leg. Ask the trucking company, not the shipping line.
The costlier mistake is forgetting what gate-out starts. Inside the port the box was running up demurrage; from the gate onward the clock that counts is detention, and it runs until the empty container is handed back. A box left standing in a yard, unloaded but not returned, is charged for every day beyond its free time.
Frequently asked questions
Does gate-out mean my container has been delivered?
No — gate-out means only that the container has left the terminal on a truck or rail car. Delivery to the door happens afterwards and is not an event that shipping lines’ trackers report.
What starts at gate-out?
The detention clock starts: the time allowed for unloading the container and returning it empty to the depot the line names. The demurrage clock, which counted the days the full box sat in the terminal, stops at the same moment.
Why does my container still show “discharged” after it left the port?
Because the gate-out has not yet reached the tracker; terminal events are passed on in batches and typically appear 6–24 hours late. It is a delay in the feed and does not mean the box is still in the port.
