After some research. Iran maintains that the strait is governed by Innocent Passage. The Strait of Hormuz is within the 12 nautical miles which is considered Territorial Waters. Also for Oman. Quote Gemini AI "Under innocent passage, a coastal state has much broader authority to regulate shipping for national security, suspend transit if it is deemed prejudicial to peace, and require prior authorization for foreign warships." Iran passed its own domestic legislation in 1993 enforcing these restrictions. Quote Gemini AI "1982 United Nations Convention on the Law of the Sea (UNCLOS), international straits used for international navigation are governed by the Right of Transit Passage" Iran signed UNCLOS in 1982 but never ratified it. Oman signed and ratified UNCLOS. Under UNCLOS the No Hinderance, Free Passage to Navigation. No tolls or fees charged for transit are followed.
