The Strait of Hormuz is a narrow waterway connecting the Persian Gulf to the Gulf of Oman. Because of its narrowness, it is one of the world's most critical chokepoints, facilitating the transit of a massive percentage of the world's liquefied natural gas and crude oil.

While Iran manages its own coastal waters, the concept of transit passage ensures that ships from other nations can move through these straits for the purpose of continuous and expeditious transit.
