China's independent refineries, known in the trade as "teapots", bought Iranian crude at prices above the global benchmark for the first time since 2022, Reuters reported on Friday. It is a small but telling sign of how profoundly the US-Iran war has reshuffled the global oil order.
What Are Teapots?
Teapots are China's hundreds of small, privately-owned refineries, concentrated in Shandong province in eastern China. As per reports, China's state-owned refiners are cautious about buying Iranian oil because they do not want to be cut off from the US dollar-based international financial system. But the teapots, which cater to a domestic market, have no such qualms.
For years, they have been Iran's most reliable customers, quietly absorbing the sanctioned oil that no one else would touch. Reportedly China bought more than 80 percent of Iran's exported oil in 2025, importing 1.4 million barrels per day.

The Old Deal And Why It Broke Down
The arrangement worked because Iranian oil was cheap. Sanctions cut Tehran off from most buyers, so it sold to China at steep discounts. Iranian oil typically traded at around $10 per barrel below Brent because of sanctions, a significant saving for refineries running on thin margins.
But when the US and Israel launched strikes on Iran in late February 2026, everything changed. Tehran shut the Strait of Hormuz, cutting off roughly a fifth of the world's oil supply. Global prices surged toward $120 a barrel. Washington, to soften the shock, temporarily lifted sanctions on Iranian and Russian crude at sea, erasing the discount that made those barrels attractive to teapots in the first place. The teapots largely stayed on the sidelines as prices soared and their margins collapsed.
The New Deal And What Triggered It
Then, this week, the calculus shifted again. Brent crude futures dropped below $100 per barrel, the lowest since March 11, after President Donald Trump announced a two-week ceasefire with Iran, contingent on the immediate reopening of the Strait of Hormuz.
Armed with fresh import quotas issued by Beijing, at least two refiners in Dongying, reportedly, purchased Iranian Light crude at premiums of $1.50 to $2 a barrel above Brent - the first time teapots have bought Iranian oil at a premium since 2022.
Adding to the price pressure: India is set to receive its first Iranian oil cargo in seven years, after Washington temporarily waived sanctions as part of managing the energy fallout from the conflict. With India now competing for the same Iranian barrels, Chinese refiners face a rival buyer they haven't had to contend with in years.

What It Means
As per reports, Beijing last week issued import quotas for 55 million metric tons of crude - roughly 401 million barrels - to independent refiners, and ordered them to keep production rates at no less than their two-year average to secure domestic fuel supply.
Maintaining those run rates at current margins would result in significant losses for teapots, but Beijing has decided energy security matters more than refinery profits right now.
The broader message is stark. Iranian oil - once the world's most discounted crude - is no longer cheap. The war changed that. And the ceasefire, fragile as it is, has only added new buyers to the queue.
