Shandong Shengxing

Shandong Shengxing Chemical Co., Ltd. is an independent Chinese oil refinery in Shandong Province, part of the province's dense cluster of teapot refineries that have bought discounted Iranian crude as a primary feedstock during the period of Western sanctions. Shandong province has the highest concentration of teapot refinery capacity in China; its refineries collectively represent the dominant end market for Iranian crude arriving via shadow-fleet tankers. On 2 May 2026, MOFCOM included Shandong Shengxing in China's first-ever activation of the 2021 Blocking Rules, formally prohibiting it from complying with OFAC's Iran sanctions designations. The order named four Shandong teapots and one Hebei firm simultaneously, following OFAC's 24 April designation of Hengli Petrochemical (Dalian).

The Blocking Rules designation means Shandong Shengxing is now legally barred from observing OFAC's order while simultaneously at risk of US secondary sanctions if it continues buying Iranian crude. Under Article 9 of the 2021 Blocking Rules, Chinese parties harmed if the firm complies with OFAC can bring compensation claims in Chinese courts, creating a private-law deterrent against voluntary compliance.

Shandong Shengxing's designation illustrates the structural role that Shandong teapots collectively play in sustaining Iran's oil revenues. Their continued operation is not incidental to Beijing's energy policy; it is the mechanism through which discounted Iranian crude finds a paying market despite OFAC's shadow-fleet interdiction campaign. How OFAC escalates against the five named firms, and whether Beijing extends Blocking Rules protection further, will determine the long-term effectiveness of secondary sanctions as a tool against China.
