The United States has imposed sanctions on a Greek linked shipping network that Washington alleges has maintained connections to Iran’s Islamic Revolutionary Guard Corps and Russia’s shadow fleet.
According to the US Treasury Department, the sanctioned network includes Hong Kong based Shipoil Limited and two Dubai based affiliates, Shipoil FZCO and Ship Fuels and Trade DMCC. The companies are controlled by Alberto and George Tsoris.
The network reportedly provides marine bunkering services and has a presence in the Greek port of Piraeus.
US authorities allege that companies within the Shipoil network have worked with Iranian petroleum businesses, entities connected to Iran’s state owned shipping company IRISL, and a wider shipping network associated with Iranian businessman Hossein Shamkhani.
Treasury records indicate that Shipoil affiliates supplied fuel during 2026 to tankers that US authorities allege were transporting cargo for Iran’s armed forces, as well as vessels controlled by Iran’s state shipping company.
The sanctions are part of Washington’s broader efforts to disrupt shipping and commercial networks that it says support Iran’s energy sector and Russia’s efforts to circumvent international restrictions.
Greek authorities have indicated that the measures were imposed directly by the United States rather than the European Union. As a result, they said there is currently no legal basis for Greece to impose corresponding domestic sanctions solely on the basis of the US designation.
The case highlights the growing scrutiny faced by Greek linked shipping interests as the United States expands enforcement against companies and maritime networks accused of facilitating trade with sanctioned entities.
