The U.S. Treasury Department on Friday announced sweeping new sanctions targeting a major Chinese independent refinery accused of purchasing large volumes of Iranian oil, marking a significant escalation in Washington’s economic pressure campaign against Tehran.
In a statement, the Treasury Department said it had sanctioned a so-called “teapot refinery” operated by Hengli Petrochemical in the port city of Dalian, China, for allegedly buying billions of dollars’ worth of Iranian crude and petroleum products. Teapot refineries are smaller, privately owned Chinese facilities that often rely on discounted oil from countries under U.S. sanctions.
The sanctions were issued through the Treasury’s Office of Foreign Assets Control (OFAC), which said that China-based independent refineries continue to play a crucial role in sustaining Iran’s oil economy. According to OFAC, Hengli has emerged as one of Iran’s largest customers for crude oil and other petroleum products, helping generate significant revenue for Tehran despite ongoing U.S. sanctions.
In addition to targeting Hengli, OFAC also sanctioned approximately 40 shipping firms and vessels allegedly involved in transporting Iranian petroleum and petrochemicals. Officials described the network as part of Iran’s so-called “shadow fleet” — a web of tankers and intermediaries that operate covertly to move oil to global markets in defiance of sanctions.
U.S. Treasury Secretary Scott Bessent said the measures are part of “Operation Economic Fury,” an initiative aimed at tightening financial restrictions on Iran. He described the campaign as an effort to impose a “financial stranglehold on the Iranian regime,” with the goal of limiting its military activities in the Middle East and curbing its nuclear ambitions.
“At President Donald Trump’s direction, Treasury will continue to constrict the network of vessels, intermediaries, and buyers Iran relies on to move its oil to global markets,” Bessent said. He warned that any individual or vessel facilitating Iranian oil flows through covert trade or financial arrangements risks exposure to U.S. sanctions.
Teapot refineries in China have become key buyers of sanctioned oil from countries such as Iran, Russia, and Venezuela, often purchasing crude at steep discounts. After losing access to Venezuelan oil following political upheaval tied to the leadership of Nicolás Maduro, many of these refineries reportedly increased their purchases from Iran.
The Treasury Department noted that independent Chinese refineries now account for the majority of Iran’s oil exports. Since at least 2023, Hengli has reportedly received shipments of Iranian crude overseen by Sepehr Energy Jahan Nama Pars Company, an oil sales arm linked to Iran’s Armed Forces General Staff. U.S. officials claim these transactions have generated hundreds of millions of dollars in revenue for the Iranian military.
Hengli’s Dalian facility is one of China’s largest independent refineries, with a production capacity of approximately 400,000 barrels per day. The company has grown into a major petrochemical player in China, producing plastics, synthetic fibers, and industrial chemicals that are widely used across Asia’s manufacturing supply chains.
Carrying Iranian oil to China is what U.S. officials describe as a vast shadow fleet of tankers operating outside normal regulatory channels. OFAC announced sanctions against 19 specific vessels on Friday, along with the shipping companies that manage them, in what analysts describe as one of the most aggressive recent crackdowns on the trade.
Industry observers told Bloomberg News that the sanctions represent a significant escalation, particularly because they target one of China’s largest independent refiners just weeks before President Trump is scheduled to meet with Chinese leader Xi Jinping. Some analysts suggested the move could serve as a potential bargaining chip in upcoming talks, while others viewed it as evidence that the administration is serious about cutting off Iran’s oil revenue streams.
Bloomberg also cautioned that the sanctions could have ripple effects across Asia. With Hengli potentially cut off from the U.S. dollar-based financial system, hundreds of chemical, textile, and synthetic fiber producers in East Asia may face supply disruptions. While competitors in China, Japan, and South Korea could benefit in the short term, the sudden market shift may also contribute to inflationary pressures, especially amid ongoing instability in the Middle East.
The financial markets reacted swiftly. Hengli’s shares reportedly dropped by 10 percent on Monday as investors assessed the potential impact of losing access to dollar transactions and global trade channels.
China’s Foreign Ministry responded sharply, condemning the sanctions as “illicit unilateral measures” lacking a basis in international law. Foreign Ministry spokesman Lin Jian urged the United States to cease what he described as the improper use of long-arm jurisdiction and vowed that China would defend the lawful rights and interests of its companies.
The sanctions underscore mounting tensions between Washington and Beijing, particularly as they intersect with U.S. efforts to isolate Iran economically. With high-level diplomatic talks looming, the latest move adds another layer of complexity to an already strained global energy and geopolitical landscape.
