New records, all IMO-linked
Every record added between the two retained OFAC publication dates contains a valid seven-digit IMO number.
OFAC vessel records · 2026-07-01 to 2026-07-20
The identifier that makes a vessel designation actionable.
Every one of the 20 vessel records added in the latest retained OFAC interval carries a seven-digit IMO number. That does not settle a screening decision, but it gives investigators a durable hull-level key with which to begin one.
01 · Finding
Names are labels. The IMO number binds the hull.
A vessel’s name, flag, operator, and ownership structure can change over time. The International Maritime Organization’s ship identification scheme exists to give a ship a persistent identifier through that change. In sanctions work, that identifier lets a list record be joined to the operational and historical evidence that a name alone cannot safely carry.
99.5%
Coverage in the wider file
1,510 of 1,517 retained OFAC vessel records carry an IMO number; 7 do not.
19
Days in the interval
The finding compares retained OFAC list publications dated 2026-07-01 and 2026-07-20; it is not a count of all designations during that period.
02 · Workflow
What the identifier enables
An IMO number improves record linkage. It is not a shortcut around investigation or a legal conclusion.
Bind the list record
Connect the designation to a specific hull rather than relying on a potentially reused or altered vessel name.
Review the evidence trail
Use the hull identifier to gather registry, flag, port-state-control, class, ownership, insurance, and voyage evidence from the relevant sources.
Apply the decision rule
Assess the applicable sanctions regime, identity evidence, ownership/control facts, and transaction context. The identifier supports the review; it does not replace it.
Important boundary: an IMO number improves identity resolution. It does not prove that a particular owner, cargo, voyage, or counterparty is sanctioned, and absence of an IMO number does not imply wrongdoing.

04 · Gap
The seven records that need another binding step
These current OFAC vessel records do not contain a valid seven-digit IMO number. That does not weaken the designation or imply wrongdoing. It means an investigator cannot use the IMO scheme as the first hull-level join and must resolve identity through other source evidence.
| OFAC ID | Vessel | Recorded flag | Vessel type | Program |
|---|---|---|---|---|
| 4238 | MAR AZUL | Cuba | Tug | CUBA |
| 17104 | RYONG GUN BONG | Democratic People's Republic of Korea | General Cargo | DPRK |
| 23424 | BONU 5 | Malta | -0- | LIBYA3 |
| 27200 | ST. VITAMIN | St. Vincent and the Grenadines | Pleasure Craft | UKRAINE-EO13661, CYBER2, ELECTION-EO13848 |
| 33809 | FU YUAN YU 8683 | China | Fishing Vessel | GLOMAG |

Data-quality boundary: these are list-record completeness observations, not findings about a vessel's legal status, ownership, activity, or compliance. The absence of an IMO in this file can have legitimate source or record-history explanations.

How this report is calculated
ArcNautical uses the retained normalized vessel records from the official US Treasury OFAC SDN CSV. We compare stable OFAC record identifiers between the two stated list publication dates, then test whether an entry’s recorded IMO value is a seven-digit number. The roster and totals in this report are computed from those downloaded records.
The IMO-number statement is limited to the official IMO ship identification number scheme. The OFAC source snapshots and SHA-256 hashes supporting the comparison are linked in the source manifest.
