The Office of Foreign Assets Control, the US Treasury bureau that administers economic sanctions, issued General License V on Friday 24 April authorising a thirty-day wind-down of transactions with Hengli Petrochemical (Dalian) Refinery Co. and its majority-owned subsidiaries through Sunday 24 May 2026 1. A wind-down licence is permission to keep paying suppliers and complete in-flight contracts inside a fixed window so a counterparty can exit without a default cascade. After 24 May, every continuing transaction with Hengli is a primary sanctions violation under Treasury's enforcement framework. The licence is the only signed Iran instrument the Trump administration has produced across sixty days of war .
Hengli Petrochemical, the Dalian-based independent refiner targeted in the designation, said in a Sunday 26 April statement that it has 'never engaged in any trade with Iran' and that crude origins fall outside US sanctions scope 2. China's Washington embassy called the OFAC action 'illegal' and threatened retaliatory measures , yet Beijing has held its formal response at embassy level. The Ministry of Commerce (MOFCOM) has issued no specific instrument; CGTN's coverage of the Putin-Araghchi meeting on Monday omits Hengli entirely 3, separating the bilateral diplomatic story from the trade designation.
The licence has structurally mattered in a way Day 60 reads do not capture. Hengli is one of the largest independent refiners of Iranian-origin crude in Northeast Asia; a successful wind-down would remove a meaningful share of the laundering capacity that has kept Iranian barrels moving through East Asian ports under sanctions for the past decade. A failed wind-down, with continuing trade after 24 May, would force Treasury to choose between escalating against the parent company in Beijing's domestic market and accepting that primary sanctions are non-binding on Chinese state-adjacent refiners. OFAC's thirty-day window has converted that choice from a policy debate into a calendar entry.
Three actors are running coordinated denial postures with one shared interest: removing the 24 May pressure without escalating before then. Hengli denies the trade; the Washington embassy protests; CGTN omits the file. OFAC's deadline lands on Sunday 24 May 2026 regardless of which posture holds.
