what happened
European regulators have opened an antitrust inquiry into Switzerland's Omya, citing possible abuse of a dominant market position. The concern is that the company may be exploiting its leading role in selling calcium carbonate to paper producers.
According to the Commission, Omya may have pushed paper-industry buyers to source all or most of their calcium carbonate from it. That could have made it harder for rival suppliers to win European customers. Omya told Reuters it is cooperating with the probe.
why it matters
Calcium carbonate lowers production costs for paper and board and improves brightness, opacity and printability, so the terms of supply feed directly into mill economics. For markets this is a single-company case in a niche segment, but it signals closer EU scrutiny of industrial input supply chains.
