U.S. Issues New Guidance for Vessels Transiting Strait of Hormuz

According to the guidance, U.S.-flagged commercial vessels should maintain maximum distance from Iran’s territorial waters where navigation allows. The advisory also instructs crews to verbally refuse any request by Iranian forces to board their vessels.

The Maritime Administration said crews should prioritise safety and avoid confrontation. If Iranian forces board a vessel, crews were advised not to forcibly resist.

Strategic Importance of the Strait

The Strait of Hormuz is a narrow waterway through which a significant share of global oil supplies is transported. Portions of the strait fall within Iranian territorial waters. In previous years, Iran has threatened to close the passage and has seized commercial ships and oil tankers, citing allegations of smuggling.

Diplomatic Context

The guidance was issued as tensions persist between Washington and Tehran over Iran’s nuclear activities. Iran’s foreign minister said on Friday that nuclear talks with the United States, mediated by Oman, had begun positively and were expected to continue.

U.S. officials have said any renewed diplomatic framework should also address Iran’s ballistic missile programme, its support for armed groups across the region, and human rights issues.

New Economic Measures

Separately, U.S. President Donald Trump signed an executive order on Friday imposing a 25% tariff on imports from any country that purchases goods from Iran, either directly or indirectly. The measure follows earlier warnings from Washington aimed at increasing economic pressure on Tehran.
