« Economic Fury »: U.S. Sanctions China’s Hengli Petrochemical in Crackdown on Iran’s Oil Trade Network

WASHINGTON — In a sweeping escalation of its “Economic Fury” campaign, the U.S. Treasury Department has imposed sanctions on China’s Hengli Petrochemical (Dalian) Refinery Co., Ltd., one of Iran’s largest customers for crude oil and petroleum products, accusing the company of playing a “vital role” in sustaining Tehran’s oil economy. The move, announced on April 24, 2026, also targets approximately 40 shipping firms and vessels operating as part of Iran’s so-called “shadow fleet,” which the U.S. Alleges facilitates the illicit transport of Iranian petroleum and petrochemicals, providing a financial lifeline to the Iranian regime.

The sanctions, enacted under Executive Order 13902, mark a significant intensification of the Trump administration’s efforts to disrupt Iran’s revenue streams, which U.S. Officials claim fund destabilizing activities across the Middle East and support Tehran’s nuclear ambitions. Treasury Secretary Scott Bessent framed the action as part of a broader strategy to “constrict the network of vessels, intermediaries, and buyers Iran relies on to move its oil to global markets,” warning that any entity facilitating these flows risks exposure to U.S. Sanctions.

Hengli Petrochemical, described by the Treasury as one of Iran’s “largest customers” for petroleum, has reportedly purchased “billions of dollars’ worth” of Iranian oil, according to the official Treasury press release. The company, a major player in China’s independent “teapot” refinery sector, now faces severe restrictions on its access to the U.S. Financial system, along with potential secondary sanctions for its business partners. The designation underscores the growing geopolitical tensions between Washington and Beijing, as the U.S. Seeks to curb China’s role in enabling Iran’s sanctions evasion efforts.

The “Economic Fury” Campaign: A Financial Stranglehold on Iran

The Treasury’s latest action is the most aggressive iteration yet of the Trump administration’s “Economic Fury” strategy, a campaign of “maximum economic pressure” designed to cripple Iran’s ability to fund its military and proxy groups across the Middle East. Since its inception in 2018, the campaign has targeted Iran’s oil exports, banking sector, and industrial base, with the stated goal of forcing Tehran to abandon its nuclear program and regional aggression.

Secretary Bessent, in a statement accompanying the sanctions, declared that the measures are “imposing a financial stranglehold on the Iranian regime, hampering its aggression in the Middle East, and helping to curtail its nuclear ambitions.” The Treasury’s press release explicitly ties the sanctions to National Security Presidential Memorandum 2 (NSPM-2), which directs the Treasury to pursue “continued campaign[s] of maximum economic pressure against Iran’s shadow banking, money laundering, and sanctions evasion networks.”

The designation of Hengli Petrochemical and the 40 shipping firms is the latest in a series of actions targeting Iran’s oil trade. In 2025, the U.S. Sanctioned several Chinese and Emirati companies for their roles in facilitating Iranian oil exports, while also designating dozens of vessels suspected of engaging in “deceptive shipping practices,” such as disabling transponders to conceal their movements. The Treasury’s Specially Designated Nationals (SDN) List, updated on April 24, 2026, now includes the newly sanctioned entities, effectively barring U.S. Persons and companies from engaging in transactions with them.

Why Hengli Petrochemical? China’s “Teapot” Refineries and Iran’s Oil Economy

Hengli Petrochemical is one of China’s largest independent refineries, part of a sector colloquially known as “teapot” refineries due to their smaller scale compared to state-owned giants like Sinopec and PetroChina. These independent refiners have become critical players in Iran’s oil trade, as they are less constrained by geopolitical considerations and more willing to purchase Iranian crude at discounted rates, often in defiance of U.S. Sanctions.

According to the Treasury, Hengli has been a key buyer of Iranian petroleum, with purchases totaling “billions of dollars” in recent years. The company’s operations in Dalian, a major port city in northeastern China, have made it a hub for Iranian oil imports, which are then processed into refined products for domestic consumption and export. The sanctions against Hengli are likely to disrupt these supply chains, potentially forcing the company to seek alternative sources of crude or face severe financial penalties.

The designation of Hengli also reflects broader U.S. Concerns about China’s role in undermining international sanctions regimes. Beijing has consistently opposed U.S. Unilateral sanctions on Iran, arguing that they violate international law and harm global energy markets. However, the Trump administration has accused China of turning a blind eye to Iranian sanctions evasion, particularly through the use of “shadow” shipping networks and covert financial transactions.

The Shadow Fleet: How Iran Evades Sanctions

The Treasury’s designation of 40 shipping firms and vessels highlights the central role of Iran’s “shadow fleet” in circumventing U.S. Sanctions. This fleet, estimated to consist of over 200 tankers by some analysts, operates outside traditional maritime norms, often using deceptive practices to conceal the origin and destination of Iranian oil shipments. Common tactics include:

• Disabling Automatic Identification System (AIS) transponders: Many vessels in the shadow fleet turn off their transponders to avoid detection, making it demanding for authorities to track their movements.
• Ship-to-ship transfers: Iranian oil is often transferred between vessels in international waters to obscure its origin before being delivered to buyers like Hengli Petrochemical.
• False documentation: Some vessels use fraudulent bills of lading or mislabel cargo to disguise Iranian oil as originating from other countries, such as Malaysia or the United Arab Emirates.
• Flag hopping: Ships frequently change their flags of registration to evade scrutiny, often registering under the flags of countries with lax enforcement, such as Panama or Liberia.

The Treasury’s action targets firms and vessels that the U.S. Alleges are directly involved in these practices, including companies registered in Hong Kong, the Marshall Islands, and Panama. The sanctions freeze any assets these entities may have under U.S. Jurisdiction and prohibit U.S. Persons from conducting business with them.

Global Reactions: China, Iran, and the Future of Sanctions Enforcement

The U.S. Sanctions on Hengli Petrochemical have drawn sharp criticism from Beijing, which has long opposed what it views as Washington’s unilateral and extraterritorial use of sanctions. China’s foreign ministry has not yet issued a formal response to the latest designations, but in past statements, it has accused the U.S. Of “bullying” and “long-arm jurisdiction,” arguing that its sanctions on Iran violate international law and undermine global energy security.

Iran, for its part, has dismissed the sanctions as ineffective, with officials in Tehran claiming that the country’s oil exports have continued to flow despite U.S. Pressure. However, independent analysts suggest that Iran’s oil revenues have declined significantly since the reimposition of U.S. Sanctions in 2018, with exports falling from a peak of 2.5 million barrels per day to roughly 1 million barrels per day in recent years. The latest sanctions could further squeeze Iran’s already strained economy, which has been grappling with high inflation, currency devaluation, and widespread public discontent.

The European Union, which has sought to preserve the 2015 Iran nuclear deal (JCPOA) despite the U.S. Withdrawal, has also expressed concerns about the escalating sanctions. While the EU has not imposed its own restrictions on Hengli Petrochemical, it has warned that U.S. Secondary sanctions could disrupt European businesses operating in China and Iran. The bloc has attempted to create a financial mechanism, known as INSTEX, to facilitate trade with Iran while avoiding U.S. Sanctions, but the system has had limited success.

What’s Next? The Broader Implications of “Economic Fury”

The Treasury’s latest sanctions are unlikely to be the last in the “Economic Fury” campaign. U.S. Officials have signaled that they will continue to target entities involved in Iran’s oil trade, including buyers, shippers, and financial intermediaries. The Trump administration has also indicated that it may expand sanctions to include other sectors of Iran’s economy, such as its petrochemical industry, which has become an increasingly important source of revenue for Tehran.

For Hengli Petrochemical, the sanctions pose a significant challenge. The company, which has not yet issued a public response, may seek to distance itself from Iranian oil imports to avoid further U.S. Penalties. However, given the scale of its operations and its reliance on discounted Iranian crude, such a pivot could prove difficult. The sanctions could also deter other Chinese refiners from purchasing Iranian oil, further tightening the financial noose around Tehran.

The broader geopolitical implications of the sanctions are equally significant. The U.S. Move risks deepening tensions with China, which has increasingly positioned itself as a counterweight to U.S. Influence in global affairs. Beijing has already taken steps to reduce its reliance on the U.S. Dollar, including through the development of alternative payment systems and increased use of the yuan in international trade. The latest sanctions could accelerate these efforts, potentially undermining the effectiveness of future U.S. Financial measures.

For Iran, the sanctions underscore the challenges of operating in a global economy dominated by the U.S. Dollar and financial system. While Tehran has sought to mitigate the impact of sanctions through barter deals, cryptocurrency transactions, and the use of front companies, these measures have not been sufficient to offset the economic damage. The latest designations could further isolate Iran from international markets, exacerbating its economic woes and increasing pressure on the regime to negotiate with the U.S.
