Who owns BMSU containers
In the Navo24 Carrier Directory, BMSU belongs to BMC Line, whose SCAC is BMSU. The line's profile, fleet and schedules are on its carrier page.
BMC Line uses BMSU on its own equipment.
A prefix tells you who owns the box, not always who books it. BMC Line also runs leased containers under lessor prefixes, and other lines can carry BMSU boxes on slot or swap deals.
How to read a BMSU container number
Every container number has eleven characters under ISO 6346. The first three letters (BMS) are the owner code registered with the BIC in Paris. The fourth letter is the equipment category: U, freight containers: the dry, reefer, open top, flat rack and tank boxes that travel on ships, trains and trucks.
Then come six serial digits and one check digit. In BMSU1234566, a format example, 123456 is the serial and 6 is the check digit. It is calculated from the first ten characters, so a single mistyped letter or digit almost always shows up as a wrong check digit.
How to track a BMSU container
Enter the full number in the box on this page: BMSU is already filled in, add the seven digits. Navo24 detects BMC Line from the prefix, reads the line's own events (gate in, loaded, departed, transshipped, discharged) and adds the vessel's live AIS position and an ETA.
If the box is not found, it may not be on an active booking yet, or the digits may be wrong. Try the bill of lading or the booking number instead: they start with the line's code, often BMSU.
Questions about BMSU
Who owns BMSU containers?
BMC Line.
How do I track a BMSU container?
Type the seven digits after BMSU into the tracking box on this page. No sign-up is needed for a single lookup.
What does the U in BMSU mean?
It is the ISO 6346 equipment category: freight container.
Is BMSU also a SCAC?
Yes. For BMC Line the container prefix and the SCAC are the same four letters, which is common but not the rule.
Why does my BMSU number show a wrong check digit?
One character is probably mistyped: O and 0, I and 1, or two swapped digits. Check the number printed on the container door or on the bill of lading.
