Columns

ColumnDescription
imoIMO ship identification number (7 digits), the stable hull identifier.
vessel_nameVessel name as listed on the OFAC SDN list.
vessel_typeVessel type per the OFAC SDN remarks (may be empty).
flagFlag state per the OFAC SDN remarks (may be empty if OFAC did not record one).
flag_transparency_tierFlag-state UBO-transparency tier. Vessels flying a sanctioned state’s own flag (e.g. Russia, Iran, DPRK) classify as unclassified — the tier addresses open-registry / flag-of-convenience use, not the sanctioned state itself. (transparent, restricted, flag_of_convenience, unclassified)
ofac_programsOFAC sanctions program code(s) for the designation, semicolon-separated, as recorded in the OFAC SDN snapshot for this release (see provenance.data_as_of).
sanctions_regimeConvenience grouping of the OFAC program(s) into a regime (Iran, Russia, North Korea (DPRK), etc.), from the OFAC SDN snapshot for this release.
mmsiMaritime Mobile Service Identity per the OFAC SDN remarks (may be empty).
call_signRadio call sign per the OFAC SDN remarks (may be empty).
ownership_resolution_stageHow far the vessel’s ownership resolves in the public GLEIF Global LEI Index. NOT beneficial ownership; a vessel with no GLEIF match may still have a registered owner in other records. (no_gleif_owner, registered_owner_no_parent, direct_parent_resolved, ultimate_parent_resolved)
