The Trump administration is late this week moving to identify, punish, and cut off remaining tankers in Iran's so-called 'shadow fleet' which are still engaged in shipping Iranian oil to Asia.
Thursday saw the US Treasury impose sanctions on 17 vessels and their owners involved in transporting Iranian crude oil, petroleum products and petrochemicals - with these being mostly aging oil tankers which conduct ship-to-ship transfers and other evasive, concealment tactics.

However, it's commonly estimated that some 20 million barrels of Iranian crude remain aboard ships which are far outside the reach of the Persian Gulf-centered US naval blockade, sitting off southeast Asian ports.
"Treasury is starving the tyrannical regime in Tehran of the money it uses to wage war in the region, and we will continue exposing those who enable the regime’s oil sales," Treasury Secretary Scott Bessent stated alongside the sanctions announcement.
"No enabler of Iranian sanctions evasion is safe from the full force of Treasury’s authorities," Bessent added.
Some of the notable specific targeting actions taken include—
- Starway was sanctioned for transporting over 3 million barrels of Iranian naphtha since 2025.
- Gas Lucky and Shenzhen were targeted for shipping more than 500,000 barrels of Iranian ethylene and 3.5 million barrels of Iran
