The United States has launched a sweeping new crackdown on Iran’s oil and petrochemical trade, unveiling fresh sanctions against companies, vessels and shipping operators allegedly involved in moving Iranian-origin petroleum products across international markets. The action marks another sharp escalation in the US pressure campaign against Tehran, with US authorities accusing the network of helping channel crucial revenue to Iran’s military establishment and the Islamic Revolutionary Guard Corps (IRGC).
Global sanctions net expands
The US Department of State announced sanctions against multiple entities spread across Qatar, Singapore, Hong Kong, the United Arab Emirates and the Marshall Islands, alleging their involvement in Iran’s so-called “shadow oil economy”.
According to the State Department, the targeted companies were engaged in the purchase, transport, sale and marketing of Iranian petroleum and petrochemical cargoes through complex international shipping arrangements designed to evade sanctions.
American authorities said the latest action forms part of a broader strategy aimed at disrupting Iran’s overseas oil revenue channels.
Petrochemical firms under scanner
The sanctions package also targeted three companies accused of trading Iranian petrochemical products, along with one senior executive linked to the operations.
US officials claimed that revenues generated through such transactions ultimately support Tehran’s military infrastructure and strategic operations.
Washington alleged that the financial networks linked to the trade provide economic lifelines to entities associated with Iran’s defence establishment.
Vessels accused of deceptive operations
The State Department designated eight vessel management companies and identified eight ships as blocked property under the sanctions regime.
US authorities alleged that several of the vessels engaged in “dark activity” and deceptive maritime practices while transporting Iranian cargoes across international waters.
Investigators claimed the shipping operations relied on layered ownership structures, covert routing methods, and concealed cargo transfers to bypass sanctions enforcement mechanisms.
Treasury targets oil sales network
Alongside the State Department action, the US Treasury Department imposed sanctions on a major oil sales network allegedly responsible for facilitating the movement of tens of millions of barrels of Iranian oil.
American officials alleged that proceeds generated through these transactions directly benefited the Islamic Revolutionary Guard Corps (IRGC), Iran’s Armed Forces General Staff, and other elements of Iran’s military structure.
The latest measures significantly widen the scope of Washington’s efforts to choke Iran’s energy exports and disrupt financial networks tied to the country’s oil trade.
