Some ships pass through the Iranian "control system" to pass through the Strait of Hormuz.

According to the British shipping media "Lloyd's List" on the 25th, the Iranian Islamic Revolutionary Guard Corps is implementing a "control system" in the Strait of Hormuz, requiring passing ships to submit complete documents, obtain a transit code, and accept Iranian escort through pre-designated channels. Since March 13, 26 ships have passed through the strait under this system. The report quoted sources as saying that ship operators are required to contact designated intermediaries associated with the Islamic Revolutionary Guard Corps before passing, submit complete documents including International Maritime Organization numbers, ownership chains, cargo lists, destinations, and full crew lists. The intermediaries will then pass on the documents to the Islamic Revolutionary Guard Corps Navy's command in Hormozgan Province for sanctions screening, cargo priority review, and "geopolitical review", with a current priority on oil transport ships. If approved, the Islamic Revolutionary Guard Corps will issue a transit code and provide route instructions. When approaching the strait, ships must verify the code via radio and be escorted into Iranian waters by pilot ships. The report mentioned that while the mainstream shipping industry has shown interest in Iran's controlled "control system", most shipping companies with detained ships have expressed that they will not have any form of contact with the Iranian Islamic Revolutionary Guard Corps due to concerns about triggering secondary US sanctions. The Iranian Foreign Ministry recently stated in a statement forwarded to all members of the International Maritime Organization that non-hostile countries' ships, if they do not participate in or support aggressive acts against Iran and strictly adhere to the published safety and security regulations, can enjoy the right to safe passage through the Strait of Hormuz after coordinating with Iranian authorities.
