Why does the US treasury watch Dalian when it comes to Iranian oil?
Dalian-based refineries, notably Hengli Petrochemical, have been identified as major buyers of Iranian crude routed through the shadow fleet.

Background

Dalian is a major port and industrial city in Liaoning Province, northeastern China, and the location of Hengli Petrochemical (Dalian) Refinery Co. Ltd, OFAC's highest-profile direct designation of a mainland Chinese commercial entity since the Iran-US conflict began in February 2026 .

Dalian is China's largest northern port city by cargo throughput and a key node in China's oil import infrastructure. Its Changxing Island petrochemical zone hosts multiple large refining and chemical complexes including Hengli's 400,000-barrel-per-day facility, which is China's second-largest independent refinery. The city's port infrastructure handles significant volumes of crude arriving from the Middle East, including sanctioned Iranian supply routed through intermediaries.

Liaoning Province is part of China's 'rust belt' industrial northeast, and Dalian's heavy industry has a long history of central government support. The Hengli designation placed the city's flagship industrial asset at the centre of the most consequential OFAC-MOFCOM confrontation since the Iran war began, with direct implications for Dalian's port throughput if dollar-clearing pressure reduces crude imports.
