Strait of Hormuz Reopens: What Does This Mean for Shipping Safety?
The Strait of Hormuz will remain closed to normal shipping until 80 mines are cleared, according to a statement from the International Maritime Organization, which cited a joint assessment by regional naval forces. The announcement followed a series of attacks on commercial vessels in the area, including a reported mine explosion near the Qeshm Island corridor on April 5, 2024.
Iran has announced plans to implement maritime fees for vessels transiting the strait, a move confirmed by the Islamic Republic’s Maritime Organization. The fees, described as “a necessary measure to ensure security and infrastructure maintenance,” will apply to all ships regardless of flag, according to a statement published by the Tehran Times. The policy, which takes effect May 1, 2024, has drawn concern from shipping industry representatives, who warn of potential delays and increased costs for global trade routes.

CNN’s live tracking map shows 12 vessels currently navigating the strait under escorted conditions, with 24 others awaiting clearance. The map, updated hourly, indicates that 37% of the 80 required mine-clearance operations have been completed, according to a technician with the Saudi-led Maritime Security Coordination Center. “The pace is slower than anticipated due to technical challenges in identifying non-metallic mines,” the technician said, speaking on condition of anonymity.
Chinese shipowners have expressed unease over the prolonged closure, with the China Shipping Association noting that 14 of its vessels are stranded in the Persian Gulf. “We are monitoring the situation closely but remain concerned about the lack of transparency in the mine-clearance process,” said a spokesperson for the association, citing internal reports. The group has begun coordinating with Gulf states to explore alternative routes, though such detours would add 10–14 days to transit times for oil tankers.
Al Jazeera’s report highlighted unresolved safety concerns, citing a U.S. Navy official who stated that “unexploded ordnance remains a risk for vessels without specialized navigation tools.” The official declined to specify the number of active mines, but a separate analysis by the London-based International Institute for Strategic Studies estimated that at least 42 of the 80 mines are still unaccounted for. The group’s report also noted that Iranian forces have increased patrols in the area, with three additional frigates deployed since March 2024.
The U.S. Department of State has called for “transparent and expedited” mine-clearance efforts, while the United Nations Security Council has scheduled an emergency session to address the crisis. No resolution is expected before the May 1 fee implementation date, according to a draft agenda obtained by Reuters.
