The Treasury Department’s Office of Foreign Assets Control (OFAC) on Tuesday designated one of the world’s largest steel-producing companies as part of its latest round of sanctions against Russia in response to the country’s invasion of Ukraine.

Magnitogorsk Iron and Steel Works (MMK) and its majority owner and board chairman, Viktor Filippovich Rashnikov, were designated pursuant to Executive Order 14024 for “operating or having operated in the financial services sector of the Russian Federation economy.” MMK ranked among the top 50 steel-producing companies globally in 2021 and is regarded as one of Russia’s largest taxpayers, according to OFAC.
