Clariant, a sustainability-focused specialty chemical company, today announced that on 16 July 2026, the company received another claim for damages against four companies, including Clariant, from Dow Europe with the court of Dortmund, Germany. The claim alleges damages amounting to around EUR 1.1 billion in relation to infringement of competition law on the ethylene purchasing market which was sanctioned by the European Commission in July 2020. Clariant firmly rejects the allegation and will adamantly defend its position in the proceedings. Clariant has substantiated economic evidence that the conduct of the parties did not produce any effect on the market.
