Ships should be prepared to encounter the US blockade, the UK Maritime Trade Operations (UKMTO) has warned in a new advisory, BBC reported.
The note to seafarers urges any vessels in the area to "maintain heightened situational awareness" and that more specific guidance is to follow.
The advisory says additional guidance for mariners regarding "how these measures will be applied in practice, including routing, verification and authorised transit producers, are in development".
UKMTO encourages anyone sailing the Gulf, Gulf of Oman, and the Arabian Sea east of the Strait of Hormuz to expect military presence and possible interception.
"These access restrictions apply without distinction to vessels of any flag engaging with Iranian ports, oil terminals, or coastal facilities," UKMTO said of the threatened blockade.
It adds: "Further clarification is expected to be provided through subsequent advisories as information becomes available."
