Iranian crude oil imports are back on the table for China’s massive state-controlled refiners. Following a surprise one-month waiver from Washington, industry giants are now weighing a return to a market they shunned for years to avoid U.S. wrath. This shift comes as the Treasury Department issues a rare licence to arrest soaring global energy costs.
China has been the biggest and nearly the only buyer of Iranian crude in recent years amid the U.S. sanctions on Tehran’s exports. However, these sanctioned barrels previously flowed almost exclusively via “dark fleets” to independent Chinese refiners. These private crude oil processors, commonly known as “teapots,” ignore international sanctions; their primary concern in choosing a supply is the bottom line. Because of the legal risks and “grey market” activity surrounding these shipments, Iranian barrels typically sell at steep discounts compared to international benchmarks.
Iranian Crude Oil Imports: The End of the “Dark Fleet” Monopoly?
Chinese state oil refiners, by contrast, have spent years staying away from Iran’s crude to avoid running afoul of U.S. financial restrictions. As massive global organisations with deep ties to the international banking system, the risk of being blacklisted by Washington was simply too high.
But the landscape shifted on Friday. Sanctions on imports of Iranian crude loaded on vessels as of 20 March are now lifted until 19 April. This window exists under a general license issued by the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC). The move appears to be a frantic attempt by the Trump administration to curb a sudden surge in global oil prices.
“Funding the Enemy”: The Geopolitical Backlash
In a highly unusual move, the waiver even allows “the importation into the United States of crude oil and petroleum products of Iranian origin.” Market analysts and political critics have reacted sharply to the news, with some describing the policy shift as effectively “funding the enemy” during a period of heightened geopolitical tension.
A Temporary Door for U.S. Imports
The licence “quietly opens that door” to U.S. importation of Iranian crude that has been prohibited for decades, says Max Meizlish, a research fellow for the Centre on Economic and Financial Power (CEFP) at the Foundation for Defense of Democracies (FDD).
Despite the opening, many experts remain sceptical. Sanctions specialists note that a one-month license is unlikely to attract a new slate of customers beyond the typical Chinese “teapot” firms. The uncertainty regarding how long this waiver—currently set to expire on 19 April—will actually last makes it difficult for state-run giants to pivot their long-term supply chains. Furthermore, other Iran-related sanctions remain firmly in place, leaving the door only slightly ajar rather than wide open.
