United Company RusAl is being investigated by the Federal Anti-Monopoly Service after a client claimed it abused its dominant market position.
RusAl may have imposed "unfavorable" supply terms, the regulator said in a statement, without identifying the client. Vedomosti earlier reported that the complainant was Valcom-PM, based in Volgograd. Valcom-PM alleged that RusAl had forced it to buy A7-grade aluminum from a smelter in Krasnoyarsk, rather than from a plant in its home region, the newspaper said, citing unidentified regulatory officials.
Those claims are groundless, and Valcom-PM has already withdrawn its complaint, RusAl's press office said Wednesday. RusAl could be fined 1 percent to 15 percent of revenue.
