Wan Hai Container Tracking: Find Your Container and Ship

Wan Hai Container Tracking: Find Your Container and Ship
In this article 7 sections

Wan Hai container tracking tells you what has already happened to your box. Wan Hai vessel tracking tells you where the ship carrying it is right now, and most people searching for the first never find the second.

There’s a wrinkle specific to this carrier that makes the gap worse than usual. Wan Hai’s own portal keeps shipment history for roughly 90 days and then the record is gone, so a box that sat in a yard for a few weeks before loading can outlive its own tracking page. The ship itself has no such limit. It has been broadcasting its position the entire time, on every leg, for as long as it has sailed.

This walks through what Wan Hai’s tracker actually shows, how to read a Wan Hai container number, and how to carry the one detail that matters, the ship’s name, onto a live map before the status page expires on you.

What Wan Hai Container Tracking Actually Tells You

Wan Hai container tracking to find your container and ship location

Wan Hai Lines grew up on intra-Asia routes, and its tracking tool shows it. Paste in a container number, bill of lading, or booking reference and you get the standard liner answer: gate in, loaded on board, any transhipment, discharge, and a final delivery date, plus the ports and ship for each leg.

What you won’t get is the stretch in between. A “loaded on board” status from eleven days ago isn’t a stalled shipment. Nothing changes at a terminal until the ship arrives, so nobody has touched it.

That’s by design. A liner’s tracking records custody, because custody is what the carrier answers for at each handover. Nobody updates a web page to say a ship is 300 nautical miles east of Taiwan doing 18 knots. But that information exists, and it’s free to look up once you know which ship you’re after.

Wan Hai Container Prefixes: WHLU and WHSU

A container number runs to eleven characters under ISO 6346: a four-letter owner code, where the last letter marks the equipment category, followed by six serial digits and one check digit. Wan Hai’s registered codes are WHLU and WHSU, both ending in the U that marks a standard freight container.

PrefixOwner
WHLUWan Hai Lines, the prefix on most of its own boxes
WHSUWan Hai Lines, a secondary registered code

So WHLU 348217 6 reads as a Wan Hai-registered freight container, serial 348217, check digit 6. Run that check digit before you assume a typo is anything worse: it is a checksum built from the other ten characters specifically so a mistyped number fails the lookup rather than quietly pulling up someone else’s cargo.

If your container carries a different prefix entirely, say TCNU or TGBU, the steel belongs to a leasing company rather than Wan Hai. That changes nothing about where you look. Wan Hai issued the bill of lading and holds the shipment record regardless of who owns the box, so Wan Hai’s tracker is still the right tool.

Reading the Container Details: Size, Type and Tare Weight

Below the event history sits the physical data that decides what the box can legally hold. Size and type come as an ISO code, where 22G1 means a 20 foot general purpose container and 42G1 or 45G1 the 40 foot and 40 foot high cube versions. Tare weight is the empty box on its own, close to 2,200 kg for a 20 footer and 3,700 kg for a 40 footer depending on build year, and it is stencilled on the door as a backup. Gross weight minus tare gives you the payload you are legally allowed to load.

The seal number is easy to overlook. It proves nobody opened the doors after stuffing.

Tare weight is the field people actually come back for, almost always over a weighing dispute. SOLAS verified gross mass rules require a shipper to declare total container weight, cargo plus tare, and getting the tare figure wrong turns a correct cargo weight into a wrong declaration that stops a box at the gate rather than at sea.

How to Track a Wan Hai Container Step by Step

The first few steps here are what Wan Hai’s own tool already does for you. The later ones are the part the portal was never built to answer.

Step 1: Collect the right reference

Wan Hai accepts a container number, a booking number or a bill of lading. The bill of lading covers everything on one shipment and works even before a specific box has been assigned, which is usually the better choice for an importer tracking a whole order.

Step 2: Pull up the status and read from the bottom

Enter the reference on Wan Hai’s own site. The event history runs chronologically, so the newest line, the one you actually care about, sits at the bottom of the list.

Step 3: Save the status before the 90-day window closes

If the shipment has already cleared or you’re researching something older, screenshot or export what you see. Wan Hai’s retention window is short enough that a record you need for a dispute can disappear before the dispute is resolved.

Step 4: Take the vessel name from the loaded on board line

That entry names the ship, usually with a voyage code, in a shape like WAN HAI 365 V021. Copy it exactly, suffix included. This is the single line that turns a static status page into a live position, and it’s the step most people never reach.

Step 5: Grab the IMO number if the page shows one

Fleet names repeat across a carrier’s own ships and across the wider industry. An IMO number is permanent for the life of the hull, so when it’s available, search that instead of the name.

Step 6: Search the ship on a live AIS map

Open MarineRadar and search the vessel name or IMO number. The ship’s page returns position, speed over ground, course, the destination the crew has entered, an ETA, and the track it has actually sailed, not just the route it was scheduled for.

Step 7: Read the speed, not the schedule

A ship holding a steady 16-18 knots on a direct heading is running to plan. One crawling at 2 knots in slow circles outside your discharge port is queuing for a berth, and it will often keep showing the same cheerful ETA the whole time it does.

Step 8: Set a zone alert and stop checking by hand

Draw a boundary around the discharge port and get notified the moment the ship enters it, instead of refreshing a status page that only moves when something official happens. Our guide to tracking port arrivals and departures covers how to set this up.

Wan Hai Vessel Tracking: Following the Ship Itself

Every commercial ship above a certain size continuously broadcasts AIS (the Automatic Identification System) over VHF radio. Coastal stations pick it up near land, satellites pick it up further out, and a live map turns that stream into the ship’s position, speed, course, heading, navigational status, draught, crew-entered destination and ETA, plus its name, MMSI, and IMO number.

What AIS never carries is cargo. No AIS message has ever included a container number, so a live map can’t look one up directly. The two systems do different jobs: Wan Hai’s system knows which box is on which ship, AIS knows where that ship is, and the vessel name links the two.

How often a ship updates depends on where it sails. Near a busy coast or port approach, coastal receivers refresh the picture often. In open ocean, reports come via satellite and the gaps can stretch to an hour or more. A ship that goes quiet mid-Pacific isn’t broken, just out of easy reach.

From Intra-Asia Feeder Network to Transpacific Carrier

Wan Hai spent most of its history as a carrier most people outside shipping had never heard of, running short intra-Asia loops between Taiwan, Japan, Southeast Asia and South Korea on ships sized for those ports rather than the open Pacific. That changed in 2020, when it launched its first transpacific services to the US West Coast, and it has kept adding capacity on that route since.

It’s still, at heart, a regional carrier that expanded outward. Kaohsiung and Taipei sit at the centre of almost every service it runs, with Hong Kong, Shenzhen, Laem Chabang and Ho Chi Minh City feeding in around them.

If your box is moving on a different Taiwan-based line, our Yang Ming container tracking and Evergreen container tracking guides cover almost identical ground, down to the shape of the container prefix. Wan Hai also now co-loads some Asia-US services with ONE, so a booking reference from either line can put your cargo on the other’s ship. Our ONE container tracking guide is worth bookmarking for exactly that reason.

Why the Wan Hai ETA and the Live Map Disagree

Sooner or later, Wan Hai will promise Thursday while the map shows the ship arriving Monday. It’s tempting to assume one of them is wrong, but neither is.

Wan Hai’s delivery date is a commercial estimate for the whole shipment, including any transhipment leg and the inland move after discharge. The AIS ETA is just a figure a deck officer typed in for the next port only, updated when there’s a spare moment. It often keeps showing the previous port’s estimate for a while after the ship leaves. So a ship can tie up on Monday while your container isn’t available until Thursday, with discharge, customs clearance, and a truck booking filling the gap.

Berth waiting is the delay neither number sees until it has already happened, and on busy Asia-Pacific legs it’s the most common reason a schedule slips.

So use the ship’s speed and track to know where the vessel really is, and Wan Hai’s dates to know when your cargo will really move again after it arrives.

What Usually Goes Wrong

  • No vessel name shows yet, because the container is still gated in or sitting at a depot. There’s nothing to search for until it’s loaded.
  • The named ship changes partway through. Transhipment through a hub port is routine on Wan Hai’s intra-Asia network, so a box can shift to a second vessel while the status page still shows the first.
  • Someone tries the container number directly on a live map. It will never resolve there; AIS carries no cargo data at all.
  • The wrong WAN HAI vessel gets tracked, because the fleet runs dozens of similarly numbered ships. Confirm with the IMO number whenever one is available.
  • The status page has aged out past the 90-day window, and the only record left is whatever was saved earlier.

Who Actually Uses Both Halves

Importers plan warehouse labour and trucking around Wan Hai’s delivery dates, then check the live map to see whether those dates are still realistic given where the ship actually is. Forwarders lean on it to answer a client during the week-long silences between portal updates, which is usually the difference between a routine phone call and an awkward one.

Hauliers feel it hardest of all. A truck booked against a ship still queuing outside Kaohsiung is a paid slot sitting idle.

Once you’re importing on this carrier regularly, you’ll have boxes on three or four different ships at once, and looking each one up separately gets old fast; our guide to tracking multiple container ships covers grouping them properly. A fair number of people searching this, though, have no shipment riding on the answer at all. They just want to watch a particular ship move, which is reason enough on its own.

Conclusion

Use Wan Hai’s own tracker for what it does well: the paperwork state of your cargo and the name of the ship carrying it, saved before the 90-day window closes. Take that name to a live map for everything the portal can’t show, and let a zone alert replace the habit of refreshing a page that only changes when something official happens.

FAQs

How can I track a cargo ship?

Search its name or IMO number on a live AIS map such as MarineRadar for position, speed, course and route history. For a Wan Hai shipment, that name comes off the loaded on board line of your own tracking status.

Yes, a Taiwan-based container carrier.

Enter the container number, booking reference or bill of lading on Wan Hai’s own tracking page for the paperwork status, then take the vessel name it gives you to a live map for the ship’s real-time position. Wan Hai’s own records only run back about 90 days, so save the status early if you’ll need it later.

Not on a live map, no. The ship carrying it is what broadcasts a signal.

Both are ISO 6346 owner codes registered to Wan Hai Lines, with the trailing U marking a standard freight container. A different prefix, such as TCNU, means the box is leased rather than Wan Hai-owned, which changes nothing about where you track it.

Accurate for what it records, which is custody checkpoints, not continuous position. A status unchanged for a week at sea is normal rather than a sign something’s wrong, and the AIS ETA on the vessel side should be read as the crew’s current estimate rather than a fixed promise.

Yes, any ship broadcasting AIS, updated continuously rather than at scheduled checkpoints.
