Under the system, vessels planning to transit the waterway will receive instructions via email from the official address info@PGSA.ir, detailing rules and regulations for passage.

Ships are required to follow the framework and obtain a transit permit before crossing the Strait, a critical chokepoint through which roughly 20% of global oil supplies pass.

The initiative, described by Tehran as a sovereign governance system, comes amid heightened tensions in the region.

Iranian forces have maintained strict control over the Strait, blocking ships linked to the United States and Israel following the launch of strikes against the country on February 28.

Tehran had previously signalled willingness to reopen the Strait after the US and Israel agreed to a Pakistan-mediated ceasefire, which also involved Lebanon.

However, Iranian authorities declared the waterway closed again, citing ongoing violations of the truce by Washington and Tel Aviv.

A draft law currently advancing in Iran’s parliament would impose a total ban on Israeli-affiliated vessels, while ships linked to the US and other “hostile” countries would face severe restrictions.

The legislation also proposes a toll system for non-hostile vessels.

Tensions escalated further after the US launched an operation on Sunday aimed at challenging Iran’s control of the Strait.

Iranian naval forces responded Monday by firing missiles and drones near US destroyers that allegedly ignored repeated warnings to stay clear.

Iranian officials have vowed to maintain sovereignty over the Strait, warning that any attempts to undermine their control will be met with force.
