Prefix and carrier caveats
MERU and related prefixes identify registered equipment and may differ from the operating carrier on a specific leg. A discharge event can be a transshipment milestone, so compare the location with the booked final port. Carrier, terminal, and feeder updates can arrive at different times, which may create temporary gaps in the timeline.
Official portal limitations
The official Mariana Express Lines portal is best for carrier-confirmed release, booking, and account-specific actions. CargoEnter is better when Mariana Express Lines milestones must be shared with customers or connected to project documents and team follow-up.
When to use CargoEnter
Use CargoEnter to keep Mariana Express Lines container events, documents, notes, and customer-visible status in one workspace.

Carrier-specific status notes
Gate in: The Mariana Express Lines shipment has reached a terminal, but it is not yet proof of vessel loading. Loaded: Use the vessel and voyage from this event as the active ocean leg for customer updates. Discharged: Check whether the port is a transshipment hub or the final destination before marking the shipment arrived.
