HMM Container Tracking

The fleet registers just two codes. HDMU dates from the Hyundai Merchant Marine decades; HMMU arrived with the shortened brand. Both resolve to HMM in the BIC register and both search identically at hmm21.com, so the code on the door tells you roughly when the box joined the fleet and nothing more.

Bills of lading carry HDMU — the rebrand changed the logo but not the SCAC, because swapping a filing code registered with customs authorities worldwide is a far bigger job than repainting ships. Paste the HDMU number under the B/L tab specifically; the container tab will reject it even though the string looks plausible.

Select the tab matching your identifier first — container, B/L or booking — then search; that ordering is the whole trick to hmm21.com. Our browser test confirmed the page ignores anything appended to the URL, so bookmarks can only take you to the empty form. For ongoing shipments the HMM e-Service app keeps a watch list, and the Hi Quote platform quotes rates instantly if you are still at the booking stage.

Not from the container. A standard dry box has no power, no radio and no satellite receiver — it is a steel case with a number painted on it, and it reports nothing about itself. Every position you see against a HMM shipment was reported by something else: a terminal crane, a gate reader, or the ship.

A live map on a carrier’s tracking page is almost always plotting AIS, the transponder every large vessel broadcasts with its position, course and speed. That is genuinely useful at sea: it is a real position rather than a schedule, and an ETA recalculated from actual movement. It is also the ship’s position, not your box’s, and the two part company the moment the container is discharged.

On land the map goes quiet. Between the gate-out and the delivery there is no vessel to follow, and the road leg appears only as whatever events the terminal and the trucker report. A container sitting on a chassis in a yard shows the last position of a ship it left days ago. Only specialised IoT equipment reports its own location, and wherever that exists it is a paid product sold to the shipper, not something a tracking page gives away.

How long a container spends at sea on HMM services, port to port. Each figure below is stated by two documents for the same service and the same pair of ports — the line’s own schedule and one more — and both are linked beside it. Where we could not find two, the pair is not listed.

These are schedule figures between two ports, not delivery times: add the days before the vessel sails and after it discharges, and expect the real voyage to drift by a few days either way. A line can change a rotation at any time, so check the date on each source.

The Asia–Europe figures are for the route around the Cape of Good Hope. On 18 October 2026 the lines’ own pages still sent these services that way; only ONE named services back through the Suez Canal (FE1, IOX). A return to Suez shortens the voyage by roughly ten days, so a figure here is out of date for any service that moves.

HMM operates in the Premier Alliance with ONE and Yang Ming, sharing vessels across the main east–west trades. The consequence shows up the first time you track: the ship named against your container can be a ONE or a Yang Ming vessel even though every document you hold says HMM. That is the alliance working as designed, not a fault in the feed.

It does not change where you search. Events follow the bill of lading, so an HDMU document resolves at hmm21.com whoever owns the hull. The one thing worth watching is a transshipment: on an alliance service the connecting leg may be operated by a partner, and the gap between discharge at the hub and loading onto the next ship is where a shipment most often appears to stall while nothing is actually wrong.

You are probably on the wrong tab. This is the failure particular to HMM. The search has separate tabs for container, bill of lading and booking, and each rejects the others silently — an HDMU document pasted under the container tab returns an empty result that looks exactly like a number that does not exist.

Both prefixes are current. HDMU predates the rebrand and HMMU followed it; both are live, both resolve to HMM, and the code on the door says only roughly when the box joined the fleet.

Links cannot help here. We opened the tracker with a number in the URL and the page ignored it, so a bookmark can only ever return you to the empty form.

Too new, or archived. The first event appears at gate-in or loading rather than at booking, and completed shipments leave the live system after some weeks.
