At least 10 vessels carrying Russia-linked cargoes of crude and refined petroleum products were approaching the United States on Wednesday, as suppliers rushed to deliver ahead of the U.S. government's deadline to wind down Russian energy purchases, data from traders and Refinitiv Eikon showed.

The United States, the world's biggest oil consumer, this month banned imports of Russian energy products due to the invasion of Ukraine, which Moscow calls a "special operation." Washington's ban gives importers until April 22 to discharge cargoes moving under pre-ban contracts.

At least one tanker carrying fuel oil heading to the United States has diverted, and at least two others that stopped at Russian terminals are awaiting discharge at U.S. ports — one since March 7, according to Refinitiv data.
