Nine tankers carrying Russian-origin crude and fuel oil have discharged in the United States in April, likely the last ones to deliver before a wind-down set by Washington expires this week, customs and tanker tracking data showed.

The United States last month set an April 22 ban on imports of Russian crude and refined products. The United States gave importers of Russian petroleum, liquefied natural gas and coal 45 days to take en route and under-contract cargoes.

Tanker Seamagic, which loaded fuel oil at Russia's Taman port, discharged at Valero Energy's St. Charles, Louisiana, refinery last week, the last of the nine tracked to discharge. The data does not include ship-to-ship transfers or Russian-origin oil loaded elsewhere.

Minerva Ellie, a vessel carrying high sulfur fuel oil (HSFO) and sold by Russia's Rosneft, also discharged at Valero's St. Charles facility, according to U.S. customs data. The cargo was chartered by commodities trader Vitol.

Vitol declined to comment on trading activity. Minerva Marine Inc., which manages Minerva Ellie, and Thenamaris (Ships Management), which manages Seamagic, also declined to comment. Valero did not immediately reply to a request for comments.

The United States imported 672,000 bbl/d of Russian crude and refined products last year, according to data from the Energy Information Administration. Of that, 30% or 199,000 bbl/d was crude, while 473,000 bbl/d was refined products.

This month, one crude and eight fuel oil tankers carrying about 6.3 million barrels and which departed from Russian ports reached U.S. ports and lightering zones, according to the data.

A 2 million-barrel cargo of Caspian Pipeline Consortium (CPC) Blend and Urals crude that departed from Russia was received in Delaware, according to ship tracking data based on the chartering contract.

CPC Blend is composed of oil from Kazakhstan and often mixed with Russian oil and loaded at Russia's Novorossiysk port on the Black Sea. The U.S. ban on Russian imports does not prohibit trading in CPC crude, but advises the Russian origin crude should be segregated.
