Iran's Islamic Revolutionary Guard Corps is implementing a formal vetting protocol for vessels transiting the Strait of Hormuz under Iranian coordination. Ships requesting protected passage must now submit comprehensive documentation: crew rosters with personnel details, full cargo manifests, voyage itineraries, and original bills of lading.
The requirement signals a shift from ad-hoc coordination toward bureaucratic gatekeeping. Rather than informal diplomatic channels (as with Indian LNG carriers), Iran is establishing a formal administrative process that allows systematic review and rejection of vessel requests.
Operational Control Mechanism
This protocol serves multiple purposes: identification of "enemy-affiliated" vessels (those bound for Israel or US ports), sanction screening, and prevention of military supply vessels. It also creates leverage—Iran can selectively grant or deny passage based on geopolitical criteria, turning the strait into a managed chokepoint rather than a free waterway.
For shippers and vessel operators, the requirement creates operational friction. Documentation gathering takes time; delays in transit coordination create voyage disruptions; and uncertainty about approval criteria increases route planning complexity.
TankerMap monitoring shows that coordinated passages (like Indian LNG carriers) have been granted clearance, suggesting Iran will permit select commerce while maintaining political control. However, the new bureaucratic overhead will likely slow traffic and create disincentives for vessels without pre-negotiated status.
