China’s Unipec arm of Sinopec has rerouted a supertanker laden with Abu Dhabi’s Upper Zakum crude away from the Rizhao port in Shandong following U.S. sanctions on the terminal there. Originally destined for discharge at Rizhao, the vessel changed course toward Ningbo and Zhoushan ports, with arrival expected around October 15.

The sanctions, which target the Rizhao Shihua Crude Oil Terminal (co-owned by Sinopec logistics unit), accuse the facility of receiving Iranian barrels from sanctioned sources. The diversion underscores how regulatory pressures are echoing into global refining logistics — complicating maritime routing and refining feedstock security.

For refiners in China and East Asia, the rerouting represents both cost and scheduling disruption. Alternative ports may impose different tariffs, bottlenecks, or transport inefficiencies, while downstream plants may need to adjust crude blends or throughput. In a tightly balanced region, even a redirected cargo can ripple across refining margins.
