How to track a M Container Line shipment
4 steps
Find your M Container Line reference. Locate your M Container Line container number, bill of lading, or booking number; it is on your booking confirmation, arrival notice, or commercial invoice.
Enter it at trackingmcp.com/track/m-container-line. Paste the reference into the search box. TrackingMCP auto-detects whether it is a container, bill of lading, or booking number and resolves it to M Container Line.
Read the live, cross-checked status. See M Container Line's own milestones, the vessel's live AIS position, the published schedule, and a forecast ETA side by side, so one stale source cannot mislead you.
Watch the demurrage & detention clock. Track the free-time countdown and get an alert before M Container Line demurrage or detention charges begin to accrue.
What you'll see when tracking M Container Line
DCSA model
Every M Container Line shipment is normalised to the DCSA Track & Trace model, so the milestones read the same as any other carrier:
Gate-inThe empty or full container enters the origin terminal or depot.
LoadedThe container is loaded onto the ocean vessel.
Vessel departureThe ship sails from the load port (the free-time clock has not started yet).
TransshipmentOn indirect routings, the box is discharged and reloaded at a hub port.
Arrival & dischargeThe vessel arrives at the destination port and the container is discharged; this is when import demurrage free time starts.
Gate-out / deliveredThe container leaves the terminal for delivery; detention free time runs until you return it empty.
M Container Line demurrage & detention free time
free-time clock
Every M Container Line import container has a free-time clock: the calendar days before demurrage (box left in the terminal) or detention (box kept out too long) charges start. Look up M Container Line's published free days by country on the free-time reference →, and TrackingMCP alerts you before the clock runs out.
M Container Line container number format, and the mistakes that break tracking
ISO 6346
A M Container Line container number follows ISO 6346: four letters, six digits, then a check digit: for example MDLN 123456 7. The first three letters identify the owner (MDLNMLII), the fourth is the equipment category (usually U).
Letter O vs zeroThe classic. Container numbers never contain the letter O in the digit positions. If tracking returns nothing, check character 5 onwards.
Spaces and hyphensFine either way; TrackingMCP strips them. But a missing final check digit makes the number unresolvable.
B/L pasted as a container numberBills of lading have a different shape (often starting MDLN). Paste it as-is and the format is auto-detected.

M Container Line tracking statuses that confuse people
5 answers
RolledYour container missed its planned vessel; usually overbooking or a schedule change, and is rebooked onto a later sailing. The new ETD/ETA shows once the carrier assigns the next vessel.
Transshipment in progressThe box was discharged at an intermediate hub and is waiting for its connecting vessel. Days without a new event here are normal; hubs often move a box only when the connection arrives.
Discharged vs. availableDischarged means the crane took the box off the ship; available means the terminal has released it for pickup after unstacking, customs and fee clearance. The gap is typically hours to a few days.
Customs or carrier holdThe container is physically at the terminal but blocked from release; customs inspection, unpaid charges, or missing documents. Tracking looks "stuck" until the hold clears.
Empty returnedThe importer has returned the empty box to the depot; the shipment cycle is complete and this is the final event on most timelines.
M Container Line tracking not updating? Six reasons
6 reasons
Carrier events lag at origin. M Container Line's own systems often post the first events 24–48 hours after gate-in or loading. If your booking is fresh, the timeline fills in as the carrier's data catches up.
The box is on a feeder or transshipment leg. Between discharge at a hub and loading onto the connecting vessel, many carriers publish nothing. The live vessel position keeps moving on TrackingMCP even when M Container Line's milestones pause.
Wrong reference type. A booking number can stop updating once the carrier splits it into containers. Track by container number for the fullest history; TrackingMCP auto-detects which type you pasted.
The shipment is too new. A booking confirmed today may not be in M Container Line's public tracking yet. It usually appears within a day of the carrier issuing the booking confirmation.
Mid-ocean quiet stretch. On a long leg there are simply no port events to report. Satellite AIS position and the forecast ETA still update daily; milestones resume at the next port call.
A typo in the reference. One wrong character (the letter O vs zero is the classic) returns an empty or stale record. Validate the number with the free ISO 6346 check-digit calculator.
