Iranian authorities announced Monday that ships transiting the Strait of Hormuz will be subject to maritime service fees [1].

This development creates a diplomatic contradiction between Tehran and Washington during a fragile period of attempted conflict resolution. Because the Strait of Hormuz is a critical global chokepoint for oil and trade, the definition of these charges determines whether the waterway is truly open or remains under Iranian financial control.

President Donald Trump said Monday that the strait had been reopened "permanently toll‑free" [2]. This statement was tied to a declared deal intended to end the war with Iran and signal a return to stability in the region [3].

However, Iranian officials provided a different interpretation of the arrangement. An Iranian official said that charging a toll is illegal under international law, but some fees are allowed for services [1]. Iran intends to charge these fees for specific services it may provide to vessels, arguing that such charges are permissible under international legal frameworks [3].

Critics and some observers suggest the distinction between a toll and a service fee is purely semantic. Some reports indicate that these fees are a code for paying for safe passage through the waterway [2].

Despite the competing claims from the U.S. and Iran, the actual flow of commerce has not yet recovered. A France 24 correspondent said that shipping remains virtually at a standstill through the Strait of Hormuz [3].

The disagreement centers on the legality of the charges. While the U.S. administration describes the waterway as free, Iran maintains that it has the right to collect payment for maritime services provided to transiting ships [1].

“"permanently toll‑free"”

The discrepancy between President Trump's 'toll-free' claim and Iran's 'service fee' policy suggests a lack of alignment on the terms of the peace deal. If Iran implements mandatory fees for all transiting vessels, it may be viewed as a de facto toll, potentially reigniting tensions over the freedom of navigation in one of the world's most sensitive maritime corridors.
