What does gate-in mean?

The truck arrives with the loaded container and the driver gives the booking number. The gate checks the container number against the booking, reads the seal, notes any visible damage and records the time. The driver receives an interchange receipt, and the box goes to the yard to wait for its vessel.

The terminal then reports the move to the shipping line as an EDI message, and the line publishes it on its tracking page. That relay is not instant: terminal events typically reach public trackers 6–24 hours after they happen.

In the chain of events a tracker shows, gate-in comes second, after the pickup of the empty container from the depot and before “loaded”, the event that names the ship and the voyage. The wording differs from line to line; the order does not.

Read the place next to the event. A gate-in at the port of loading is the one described here. Some trackers use the same word once more at the far end of the journey, for the empty container arriving back at a depot — that one is the empty return. The tracking guide walks through all eight events in order.

A terminal accepts containers for a given vessel only until the cut-off printed on the booking confirmation. A box that reaches the gate later is not loaded on that ship; it is rolled to a later sailing. The shipper pays for the days in between and explains the delay to the buyer. Plan the truck for the day before the cut-off, not for the hour of it.

The quieter mistake is expecting tracking before gate-in. Carriers publish the first event only after the box has entered the terminal or been loaded, typically 24–48 hours after it enters the system. A shipment booked yesterday has nothing to show, and searching again changes nothing. Nor does an empty result mean that the booking has failed.
