COSCO Container Tracking

Three of the four codes — CSNU, CCLU and CSLU — sit plainly under COSCO Shipping Lines in the BIC register. CBHU is the oddity: the registration names Florens, the container-leasing company inside the same group, while the boxes circulate in COSCO’s operated fleet. Aggregator sites split on how to label it; our checker follows operational reality and points CBHU at the COSCO tracker.

Documents issued by COSCO Shipping Lines carry the COSU SCAC ahead of the number — distinct from every container prefix in the fleet, so a COSU string pasted into a prefix validator will rightly be rejected as “not a container”. The eLines search accepts it directly, and tracking at B/L level is the sensible default when a booking covers several boxes moving together.

Manual entry is the rule here: our tests confirmed that elines.coscoshipping.com ignores any number smuggled into the URL, presenting a blank form every time. Once submitted, the timeline runs from empty-container pickup through vessel legs to final gate-in, in English despite the .com/.cn duality. The COSCO Shipping Lines app mirrors the feed and adds subscription alerts, which beats polling the site during a long transpacific crossing.

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 COSCO Shipping Lines 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 COSCO Shipping Lines 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.

COSCO completed its purchase of OOCL in 2018 and kept both brands trading separately. For an owner that is a corporate detail; for anyone holding a document it is the single most common way a COSCO search fails. The two lines run separate tracking systems, and neither resolves the other’s bills of lading.

The rule is simple and it is about paperwork, not ownership: search where your document was issued. A COSU bill of lading belongs on elines.coscoshipping.com; an OOLU one belongs on the OOCL site. The same is true across the wider Ocean Alliance — COSCO shares vessels with CMA CGM, Evergreen and OOCL, so the ship named against your box often belongs to a partner, and that changes nothing about where the events are published.

You may be on the wrong one of the two. See above: an OOCL document does not resolve here, however closely the two companies are related.

CBHU looks like someone else. That prefix is registered to Florens, the leasing company inside the same group, so prefix lists elsewhere file it as a lessor and people stop looking. Those boxes run in COSCO’s operated fleet and track here normally.

Check the digit before retrying. Four prefixes that all begin with C make a misread first letter easy. The checker here catches a single wrong character, which is the cause of most failed searches at every line.

Too new, or archived. Events begin at gate-in or loading, not at booking, and finished shipments leave the live system after some weeks.
