The Russian-flagged Nord managed to clear the strait despite private vessels largely avoiding the waterway since the outbreak of hostilities.
While long-term peace negotiations stall between the two sides, Tehran has this week focused its diplomatic efforts on cementing its relationship with Russia.
Russian President Vladimir Putin hosted an Iranian delegation in St Petersburg on Monday, where Iranian Foreign Minister Abbas Araghchi hailed their “strategic relationship”.
Putin told Araghchi that the Iranian people were “courageously fighting” for their sovereignty in the face of American and Israeli pressure, Russian state-run news agency Tass reported.
Araghchi shared photos on X showing him smiling and shaking hands with Putin and his Russian counterpart Sergei Lavrov.
He wrote: “Recent events have evidenced the depth and strength of our strategic partnership.
“As our relationship continues to grow, we are grateful for solidarity and welcome Russia’s support for diplomacy.”
