Chinese refineries continue to benefit from discounted Iranian crude, a critical component of their energy strategy, despite intensified scrutiny and sanctions from the United States. Iran remains a significant supplier, leveraging a clandestine network of “dark fleet” tankers and intermediaries to evade U.S. sanctions. However, this covert supply chain faces heightened challenges, with Washington expanding measures targeting shipping routes and operators associated with these operations.
Iranian crude oil, often disguised as originating from Malaysia or Oman, constitutes about 13% of China’s total oil imports. Shipments have reached an estimated 1.4 million barrels per day this year, up significantly from earlier periods. Much of this oil is funneled through smaller, independent Chinese refineries known as “teapots,” which rely heavily on cost-effective supply sources to maintain operations amid narrowing profit margins.
China and Iran have crafted a trade system designed to bypass dollar transactions and U.S. oversight, utilizing Chinese yuan and intermediaries to shield their dealings. This setup has made it challenging for global regulators to enforce compliance. However, under the prospect of Donald Trump returning to the U.S. presidency and reinstating his administration’s “maximum pressure” campaign, sanctions enforcement could escalate further, potentially disrupting China’s energy imports and raising costs for refiners.
Expanded measures implemented by Washington in October include targeting vessels involved in ship-to-ship transfers of Iranian oil. This has caused delays in deliveries, forcing refiners to seek alternative methods to secure supply lines. While Beijing officially defends its oil trade with Tehran as lawful, the geopolitical stakes are high, with Western policymakers wary of letting discounted Iranian crude further entrench China’s energy security at odds with U.S. sanctions policies.
China’s appetite for Iranian oil reflects broader economic challenges, including lower-than-expected domestic fuel demand and weak refining margins. Many refineries are already struggling to remain profitable, and tougher sanctions enforcement could exacerbate their woes. Market experts predict that any disruption to Iranian oil imports might also create ripple effects across global markets, affecting oil prices and supply chains.
Meanwhile, China’s strategic ties with Iran are underpinned by a broader geopolitical alignment. Both nations seek to counterbalance U.S. dominance in the global oil market. Tehran views China as a lifeline to maintain its crude exports, while Beijing relies on these discounted imports to bolster its economic competitiveness. This intricate relationship continues to challenge U.S. efforts to isolate Iran economically.
