Ukraine's Office of Prosecutor General is probing charges of underpayment against FPM and another subsidiary, Ferrexpo Yeristovo Mining (FYM), which represents the group's second largest mine.
FPM received a tax audit report in February 2022 which charged that underpayment of iron ore royalty payments from April 2017 to June 2021 amounted to about $35.6 million.
Ferrexpo on Tuesday denied all accusations made as part
of the investigation and said it would appeal the decision.
The court order adds to Ferrexpo's legal tussles in Ukraine.
Last September, an appeal court
ruled that a share sale in FPM sold to entities owned by former CEO Kostyantin Zhevago in 2002 was invalid, and that the 40.19% stake needed to be transferred to the unit's former shareholders.
The group last said at the time it was exploring all
options, including appealing to Ukraine's Supreme Court.
Zhevago, who is also Ferrexpo's controlling shareholder, stepped down from the group's board in late December shortly after he was arrested in France at Ukraine's request on suspicion of embezzlement and money-laundering.
Ferrexpo, the world's third-largest exporter of iron ore pellets, has all its operations in Ukraine.
Last month it reported a
slump in annual production
of pellets owing to higher costs, logistical constraints
and disruptions caused by Russia's invasion of Ukraine.
