The letter to IMO member states, seen by the newspaper, says that "non-hostile vessels" should be able to pass through the strait "in coordination with Iranian authorities."
The Foreign Ministry in Tehran said that Iran "has taken necessary and proportionate measures to prevent the attackers and their supporters from exploiting the Strait of Hormuz to promote hostile operations against Iran."
At the same time, the ministry said that ships with links to the US and Israel, as well as "other participants in the aggression," do not qualify for the measure.
Oil prices fell late Tuesday evening. A barrel of North Sea oil that cost $103.5 at 9 p.m. Swedish time fell to $99.7 an hour and a half later.
Traffic through the strait, where about a fifth of the world's oil normally passes, has almost completely ceased since the US and Israel's war against Iran began on February 28.
Around 3,200 ships are stuck in the Persian Gulf waiting to pass through the Strait of Hormuz.
