Who owns SIKU containers
In the Navo24 Carrier Directory, SIKU belongs to Samudera Shipping Line, whose SCAC is SIKU. The line's profile, fleet and schedules are on its carrier page.
Samudera Shipping Line uses SIKU on its own equipment.
A prefix tells you who owns the box, not always who books it. Samudera Shipping Line also runs leased containers under lessor prefixes, and other lines can carry SIKU boxes on slot or swap deals.
How to read an SIKU container number
Every container number has eleven characters under ISO 6346. The first three letters (SIK) 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 SIKU1234560, a format example, 123456 is the serial and 0 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 an SIKU container
Enter the full number in the box on this page: SIKU is already filled in, add the seven digits. Navo24 detects Samudera Shipping 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 SIKU.

Samudera Shipping Line.
How do I track an SIKU container?

It is the ISO 6346 equipment category: freight container.
Is SIKU also a SCAC?
Yes. For Samudera Shipping Line the container prefix and the SCAC are the same four letters, which is common but not the rule.
Why does my SIKU 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.
