The Treasury also sanctioned Chinese refinery and dozens of vessels linked to Iran’s shadow fleet.
U.S. Treasury Secretary Scott Bessent said on April 24 that the United States will not renew the sanctions waivers that enabled buyers to take delivery of Iranian and Russian crude already loaded on tankers at sea.
Bessent said a one-time license covering Iranian oil on the water would not be extended, calling it “totally off the table.” The parallel waiver for Russian oil and petroleum products will also be allowed to end, he said.
“We will not be renewing the general license on Russian oil, and we will not be renewing the general license on Iranian oil,” Bessent said. “That was oil that was on the water prior to March 11. So all that has been used.”
The Treasury Department’s Office of Foreign Assets Control (OFAC) also on Friday sanctioned Hengli Petrochemical (Dalian) Refinery Co., a Chinese plant that can process roughly 400,000 barrels a day.
“Hengli has played an outsized role in purchasing crude oil from Iran’s armed forces,” the Treasury said in a statement.
The OFAC also sanctioned approximately 40 shipping companies and tankers connected to Iran’s so-called shadow fleet.
The action was executedunder Executive Order 13902 and President Donald Trump’s National Security Presidential Memorandum 2, the framework for the White House’s “maximum pressure” campaign.
“Treasury will continue to constrict the network of vessels, intermediaries and buyers Iran relies on to move its oil to global markets,” Bessent said in the Treasury statement.
On Friday, Bessent also disclosed the seizure of about $344 million in cryptocurrency held in crypto wallets the government has tied to Tehran.
“We will follow the money that Tehran is desperately attempting to move outside of the country and target all financial lifelines tied to the regime,” Bessent said.
Blockchain analysts cited in the report tied some of the wallets to the Central Bank of Iran and to Iranian cryptocurrency exchanges.
Bessent predicted earlier in the week that Iran’s oil sector was close to collapse. He said Kharg Island, the terminal that handles nearly 90 percent of Iran’s crude exports, would run out of storage “in a matter of days,” meaning producers had to shut in fragile wells that are hard and costly to restart.
