FAS took on coking coal producers after a sharp rise in prices. The antimonopoly service demanded that the largest coal miners explain the October increase in coal prices. Companies must disclose their cost structure, production and sales volumes, supply plans and justify the reasons for the price increase. In October, domestic coking coal prices jumped by 19.5-35.7% compared to September, to 9.5-15.3 thousand rubles. The tone depends on the brand. The price increase comes against the background of strengthening global prices and rising costs. At the same time, the cost of production in Kozbas during the year, according to various estimates, increased by 10-15%. So far the matter has been reduced to requests for manufacturers. Possible sanctions will only be discussed if the service finds violations. Koala on Telegram | up to MAX.
