The largest ammonia producer in Russia OJSC Togliattiazot has filed a lawsuit to the international commercial arbitration court of Ukraine's Chamber of Commerce and Industry asking to collect $11.5 million from state-run enterprise Ukrkhimtransammiak.

"Togliattiazot believes that Ukrkhimtransammiak violated the contract liabilities in ammonia transit halting it unilaterally. The decision to appeal to court was made after top managers of Ukrkhimtransammiak refused to satisfy the Togliattiazot's claim sent on January 13, 2017 and settle the situation via talks," reads the report.

According to Togliattiazot, the supplement proposed by the Ukrainian company foresees the groundless increase in the transportation cost. The Russian company does not want to sign it.

"If Ukrkhimtransammiak does not start implementing its contract liabilities, losses would continue growing and Togliattiazot will try to collect them, including in international courts," Togliattiazot Director General Vyacheslav Suslov said.

As reported, referring to Ukrainian Economic Development and Trade Minister Stepan Kubiv, Ukrkhimtransammiak, the operator of the Togliatti-Odesa ammonia pipeline, will be able to resume pumping after signing the new agreement with the Russian company.
