Short answer: two HASU containers we ran through our tracking API on 4 November 2026 came back under Maersk. For the booking behind an old Hamburg Süd box, Maersk names two places: the Historic tab of a Maersk account and, for the time being, the old Hamburg Süd website.
The second one is where Hamburg Sud container tracking gets confusing. Maersk’s page for Hamburg Süd customers says previous bookings can be read on the Hamburg Süd website with the old login. On 4 November 2026 the address hamburgsud.com answered with a 301 redirect to maersk.com. We checked the front page and the /en/ page, not a booking login. Our reading: try the Maersk account first.
The line itself is easy to place. Navo24’s carrier page describes Hamburg Süd as a German line founded in 1871, a Latin America and reefer specialist, owned by Maersk since 2017, with the carrier code SUDU. On 19 June 2023 Maersk told customers that Hamburg Süd was unifying with the Maersk brand, in stages.
What the two Maersk pages say
The advisory of 19 June 2023 says the transition would be staggered and that customers would hear from Maersk when it was time to transfer their business. It also says the Hamburg Süd social media accounts and newsletters would be phased out, with the content moving to Maersk equivalents.
The page titled “Hamburg Süd is now Maersk!” carries no date, but it reads as the later of the two. It says that for the time being previous Hamburg Süd bookings can be viewed on the Hamburg Süd website with Hamburg Süd details, that Maersk will give as much notice as possible before closing that website, and that customers should start downloading and saving any information they need longer term. In a separate answer about shipment information, Maersk says the Maersk account holds all historical and current information, including Hamburg Süd bookings. Log in with Maersk credentials, open the Historic tab on the top menu, or search for the container as usual.
Where does Hamburg Sud container tracking start for an old number?
A bare container number is the quickest to test. Navo24’s Hamburg Sud carrier page says the owner prefixes include SUDU and HASU. The same page says it accepts a container, bill of lading or booking number. It also says a single lookup needs no sign-up.
A booking needs a login, either the Maersk one or the old Hamburg Süd one.
If you have no Maersk login, register on Maersk.com. A verification link comes by email, and clicking it finishes the registration. Maersk also publishes a website guide for registering, logging in, making bookings, managing shipments and finding invoices. For what the guide leaves out, it points to its Sales and Customer Experience teams.
EDI and API bookings are a third case. Maersk says its teams guide the switch to the Maersk EDI channel and that in most cases they have already been in touch. Customers are advised to keep their other accounts active so updates on previous and current shipments keep arriving, and Maersk has asked third-party providers to keep sending EDI cargo status messages until those shipments are complete.
What two HASU boxes returned on 4 November
None of the 4,145 containers tracked under our API key started with SUDU. Two started with HASU, the other owner prefix the carrier page lists. At 20:28 UTC (22:28 in Kyiv) we ran both through the lookup endpoint of the tracking API.
Both responses named Maersk as the carrier.
HASU4670162 is a 40-foot high cube (ISO type 45G1) and came back as discharged, on the vessel AL RIFFA. Its nine events, in the local time of each place:
| Local time | Event | Place |
|---|---|---|
| 7 Sep 11:10 | Gate in | GBLBA |
| 7 Sep 23:19 | Gate out | GBLBA |
| 8 Sep 08:30 | Gate in | GBLGP |
| 12 Sep 00:52 | Loaded | GBLGP |
| 12 Sep 17:53 | Departure | GBLGP |
| 20 Oct 17:31 | Arrival | INMUN |
| 21 Oct 10:12 | Discharged | INMUN |
| 25 Oct 20:53 | Gate out | INMUN |
| 27 Oct 22:08 | Gate in | no code given |
HASU4155157, also a 40-foot high cube, was still at sea on the vessel MARINA SAPPHIRE, sailing from Nansha to Ho Chi Minh City. It was loaded on 1 November at 17:16 and departed on 2 November at 06:56 (both China time), and the response carried a planned arrival of 5 November at 08:00 local time, with an ETA confidence of 80 percent.
Both responses left the bill of lading and booking number fields empty. Per Maersk, the booking behind such a box sits in the Maersk account or on the old Hamburg Süd website. We tested neither: we have no Hamburg Süd login, and nothing here shows what the Historic tab displays.
What the sources leave open
Maersk’s two pages give no date for closing the Hamburg Süd website and no date by which every customer is carried over. The 2023 advisory says the process is staggered and will take several months. The redirect check was one request to hamburgsud.com and one to hamburgsud.com/en/ on 4 November 2026, and the booking login was not tested.

Which contact details work for Hamburg Süd accounts?
The same page says that in most cases staff have already replied from Maersk email addresses, and that for the time being both the Hamburg Süd and the Maersk contact details are active.
Did the trade routes change when the brand was unified?
Maersk's answer on its Hamburg Süd page is that the current network design is brand agnostic and is not affected by the brand unification.
