A container shipment generates a dozen or more tracking events between origin and final empty return. This guide walks through every milestone in lifecycle order — what each means, how carriers label it, and what operational decision it should trigger.
A container shipment generates a dozen or more tracking events between the origin terminal and the final empty return. Each event marks a custody transfer, a milestone, or a status change — and each one carries a different name depending on which carrier you are tracking.
This guide walks through every tracking milestone from Gate In at origin to Empty Returned at destination, in lifecycle order. For each event, you will find what it means, how carriers label it, when to expect it, and what operational decision it should trigger.
Gate In
Definition
Gate In is the tracking event that records when a laden (loaded) container enters the terminal at the port of origin, passing through the terminal gate and into the yard for staging before vessel loading.
Explanation
Gate In marks the moment a container transitions from the shipper’s or trucker’s control to the terminal’s custody. The container has been stuffed with cargo, transported by truck or rail to the port, and cleared through the terminal gate. At the gate, the terminal operator records the container number, seal number, weight, and condition — creating the first terminal-generated event in the tracking timeline.
This event is distinct from the booking confirmation or empty container pickup that precedes it. A booking can be confirmed days or weeks before Gate In occurs. The empty container may have been released from a depot, transported to a warehouse for stuffing, and then trucked to the terminal — none of which appears in carrier tracking. Gate In is when the terminal’s system first sees the container. (....)
