Iran’s shadow fleet relies on little-known ship management companies to operate its tanker fleet, which Tehran uses to disguise Iranian oil shipments to China through ship-to-ship (STS) transfers involving sanctioned vessels. On May 08, 2025, the United States imposed sanctions on the tanker IMO 9171448. According to IMO’s Global Integrated Shipping Information System (GISIS) data as of July 14, 2025, the vessel’s registered name is IMPALAS, flag unknown. ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: flagst us_ofac_sdn ofac-541202025-08-08 Vessel: id5792bd08ca869124907f3403679d10b845a0b9a5 us_sam_exclusions usgsa-s4mrwcfx52026-01-06 Vessel: id0a6a59c3511b6e93dd2190379b347a63137d34ed ext_us_ofac_press_releases ofac-pr-5912abaaffb9d8468505cd38fdfb7aebf2c817732026-01-06 Vessel: ide126a62f0a0218547b43273e20ecd52c106d9692 us_trade_csl ofac-541202026-01-06 Vessel: idb661bf9fe00403e02f00942525c6a6082b6ca5fe us_ofac_sdn ofac-541202026-01-06 Vessel: id90a4f218c2ac104aa70f4d81b0a1c018d53604df ua_war_sanctions ua-ws-vessel-10922026-01-09 Vessel: imoNumberIMO9171448 eng us_ofac_sdn ofac-541202025-05-08 Vessel: imoNumberIMO9171448 ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: mmsi668116257 eng us_ofac_sdn ofac-541202025-05-08 Vessel: nameIMPALAS ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: nameIMPALAS eng ext_us_ofac_press_releases ofac-pr-5912abaaffb9d8468505cd38fdfb7aebf2c817732025-12-31 Vessel: nameIMPALAS us_trade_csl ofac-541202025-05-08 Vessel: nameImpalas eng us_ofac_sdn ofac-541202025-05-08 Vessel: nameIMPALAS eng us_sam_exclusions usgsa-s4mrwcfx52025-05-24 Vessel: notesIran's 'ghost armada' ua_war_sanctions ua-ws-vessel-10922026-01-09 Vessel: pastFlagsmh ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: pastFlagsst ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: pastFlagsgr ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: pastFlagspa ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: previousNameMaran Callisto ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: previousNameAstro Callisto ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: programIdUS-IRAN eng us_ofac_sdn ofac-541202025-06-02 Vessel: programIdUA-WS-MARE ua_war_sanctions ua-ws-vessel-10922025-10-09 Vessel: registrationNumberEJ2HFSKX9GX3 eng us_sam_exclusions usgsa-s4mrwcfx52025-05-24 Vessel: sourceUrl https://home.treasury.gov/news/press-releases/sb0135ext_us_ofac_press_releases ofac-pr-5912abaaffb9d8468505cd38fdfb7aebf2c817732025-12-31 Vessel: sourceUrl https://sanctionssearch.ofac.treas.gov/Details.aspx?id=54120us_ofac_sdn ofac-541202025-05-08 Vessel: topicssanction us_trade_csl ofac-541202025-12-30 Vessel: topicsmare.shadow ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: topicssanction us_ofac_sdn ofac-541202025-05-08 Vessel: topicspoi ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: topicsdebarment us_sam_exclusions usgsa-s4mrwcfx52025-12-29 Vessel: type20 ua_war_sanctions ua-ws-vessel-10922025-10-06 Vessel: typeCrude Oil Tanker eng us_ofac_sdn ofac-541202025-05-08
