Letter from Iran: US sanctions cut off crude supply line
Deliveries to China decline by around 1m b/d from move to curb crude exports to Shandong port, putting Iran under further economic pressure

The directive comes after a surge in sanctioned crude tankers visiting key Chinese terminals, raising concerns about potential disruptions in supply for independent Chinese refiners, or ‘teapots’. These refiners have relied on discounted Iranian crude, especially since 2020 when flows from Iran to China started to ramp up, and such restrictions could worsen the challenges Iran faces in its oil export operations. Iran’s oil deliveries to China have sharply declined, according to recent data. Volumes dropped below 850,000
