WPB states that, in October 2025, the US government widened its drive of sanctions against individuals and entities connected to the Iranian oil and LPG trade, but particularly China-associated ones. The Office of Foreign Assets Control (OFAC) at the Treasury Department designated more than 50 individuals, companies, and vessels to its blacklists, with a view to closing down revenues streams financing Tehran's military and geopolitical ambitions.
Center to the sanctions is Rizhao crude oil terminal in Shandong province, a terminal that imports a significant percentage of China's imported crude. The U.S. accuses this terminal of having been found to be engaged in refining Iranian-origin crude, and it is reported to represent approximately 9 percent of China's crude imports. As some of its capital is pegged to Sinopec, one of China's biggest state-owned refiners, the naming sends strong signals to the other Chinese refining and importing players. By targeting Rizhao, Washington threatens to disrupt not only Iranian flows but broader Chinese crude logistics — even though Iranian volumes at this terminal are estimated to account for relatively modest shares of its overall throughput.
Another of the high-profile sanction targets is the Shandong Jincheng refinery, one of the so-called "teapot" (i.e., privately held) refineries with near-daily throughput of about 120,000 barrels. It is the fourth Chinese independent refinery sanctioned under Trump administration measures for continued purchases of Iranian oil despite previous U.S. pressure. The move is meant to send a sharper message to smaller refineries: fall in line—or get cut off from international financing.
In addition to terminals and refineries, some 20 percent of Iran-owned very large gas carriers (VLGCs) – vessels that transport liquefied petroleum gas – were also targeted in this round, along with 16 oil tankers believed to be owned by the shady "shadow fleet" used to conceal the origin of Iranian cargoes. The actions are part of a broader approach by the U.S.: not only attacking the producers and intermediaries, but attacking the shipping and logistics networks that facilitate sanctions evasion.
Strategic Goals and Broader Consequences
The Trump administration places these sanctions within the framework of a "maximum pressure" diplomacy aimed at isolating Iran's ability to fund its nuclear and missile programs, and its foreign proxies. Secretary of the Treasury Scott Bessent stated that these measures are intended to hurt Iran's cash flow by eliminating crucial components of its energy export apparatus.
By penalizing Chinese players, the U.S. is ratcheting up the stakes in Sino–U.S. trade and energy diplomacy. Chinese state refiners such as Sinopec can now count on heightened resistance in procuring crude, as some key terminals—Rizhao among them—are now subject to punitive measures. Analysts expect this to push Chinese buyers either to assume logistical costs, redirect shipments via other ports, or reduce Iranian supply.
Besides, the sanctions continue on a pattern: this is the fourth series of Chinese refinery sanctions in the present cycle of U.S. policy.
The U.S. is also expanding its reach by going after LPG-trading companies, shadow fleet shipping lines, and shell corporations assisting in laundering or concealing Iranian oil exports.
But these steps are expensive for diplomacy and operations. China is committed to its sovereign rights and access to oil, and the pressure may raise the heat at future U.S.–China negotiations. Iran can, in turn, double down on secret trading routes, vehicle transfers, ship-to-ship transfers, and other evasion tactics.
Challenges, Risks, and Outlook for the Bitumen Sector
To bitumen, asphalt, and heavy-oil industry stakeholders (which are apt to use fuel oil or petroleum feedstocks), the sanction spillover effects are worthy of close examination:
1. Fuel and Feedstock Markets
When Chinese crude importers are dislocated, the cost of crude and heavy residials can increase, altering price spreads among bitumen feedstocks. Some supply avenues can become curtailed, possibly with higher-import prices.
2. Logistics and Shipping
Terminal and vessel sanctions can cause bottlenecks in transportation or force alternative routing. That could raise insurance, freight, and transshipment fees for petroleum and bitumen-type commodities.
3. Secondary Sanctions Risk
Companies that supply or use heavy residues that are associated with Iranian origin risk being targeted. Downstream players—refiners, transporters, traders—are asked to harden their compliance efforts to avoid inadvertent exposure.
4. Geopolitical Uncertainty
Escalations involving the U.S., China, or Iran could lead to additional sanctions, retaliations, or disruptions of petroleum flows globally. International business bitumen companies must monitor developments closely.
5. Diversification and Alternatives
Certain companies can accelerate diversification—seeking alternative crude sources, increased use of domestic sources, or investing in more flexible blending and recycling plants to reduce exposure to volatility through imports.
In the future, the success of this sanctions wave will depend on consistency of enforcement, global backing (or opposition), and Chinese or Iranian countermeasures. China's decision on how to resist, comply, or quietly alter its routing will have much to do with it.
Conclusion
In October 2025, the United States escalated its sanctions drive by targeting over 50 units and vessels with connections to Iran's oil and LPG trade—especially those routed through China's terminals, refineries, and shipping networks. The measures are intended to choke off revenue streams fueling Tehran's ambitions in the region, but also create unintended side effects for global oil supply logistics, trading relationships, and downstream operations like bitumen production.
Strategically, the measures are an intensification of Trump's "maximum pressure" policy with an enhanced focus on China-related networks. For the bitumen sector, higher feedstock costs, shipping dislocation, and supply risk are in the limelight. Businesses must stay nimble, bolster compliance, and proactively diversify supply chains in their efforts to ride through the impending tempest.
