Iran effectively shuttered the crucial waterway in the early days of the war and in mid-April the US responded by imposing its own blockade on Iranian ports,

Iran's foreign ministry said on Monday that Tehran was collecting fees for "navigational services" on ships transiting the strategic Strait of Hormuz, but is not imposing tolls.
"The services that are provided - navigational services in addition to the measures necessary to protect the environment of the Strait of Hormuz, the Persian Gulf and the Sea of Oman - require the collection of certain fees," foreign ministry spokesman Esmaeil Baqaei said in a weekly press briefing.
He added that Iran was "not seeking to collect tolls."
Last week, Iran published a map claiming regulatory control over a stretch of the Strait of Hormuz that extends deep into the territorial waters of the United Arab Emirates and Oman, prompting five Gulf states to formally warn shipping companies through the International Maritime Organisation (IMO) not to comply.
In a post on X, Iran's Persian Gulf Strait Authority defined its claimed management zone as running from Kuh-e Mobarak in Iran to the south of Fujairah in the UAE at the strait's eastern entrance, and from the end of Qeshm Island in Iran to Umm al-Quwain in the UAE at its western entrance.
