Hengli Petrochemical faces US sanctions over alleged Iranian oil dealings, while China invokes its blocking law, creating uncertainty for investors.

Hengli Petrochemical shares have come under pressure after the U.S. Treasury’s Office of Foreign Assets Control (OFAC) added Hengli Petrochemical (Dalian) Refining Co., Ltd. to the Specially Designated Nationals (SDN) List on April 24, 2026, citing alleged participation in Iranian oil transactions.Geopolitechs as of 05/08/2026 The move restricts U.S. persons from dealing with the entity and may expose non?U.S. counterparties to secondary sanctions risk, amplifying geopolitical and regulatory uncertainty around the stock.The Straits Times as of 05/08/2026
