India’s Calibre Buys RheinPerChemie from Evonik

Indian specialty chemicals company Calibre Chemicals has agreed to acquire RheinPerChemie (RPC) from Evonik. Based in Rheinfelden, Germany, RPC manufactures ammonium and sodium persulfates.

Calibre, which regards itself as India’s largest producer of potassium persulfate, perchlorates and iodine derivatives, said the acquisition will turn it into a global supplier of a full range of persulfates while also expanding its presence in the European market.  

“The RPC acquisition will accelerate organization learning to provide best-in-class products and services to customers and enhance customer centricity for all our business lines in Europe. Teams across the two continents would work together to expand our electrochemistry capability and capacities to further improve existing products and manufacture new products as well,” said Calibre CEO Deepak Chander.

The two companies’ offerings are complementary and revenue accretive. The Mumbai-based firm added that once the deal has closed, Calibre will also be a “front runner for Indian specialty chemical companies investing in green electrochemical opportunities in the western world.”  

Calibre plans to further strengthen manufacturing at RPC and will also add new persulfates capacity in other geographies.  

Singapore-based private equity group Everstone Capital bought a controlling stake in Calibre on Aug. 31, 2021 with the aim of transforming the Indian firm from a family-owned business to a global player.

Calibre supplies customers in Europe, the Americas, Africa and Asia, with two thirds of its revenue generated by exports. The company operates a manufacturing plant in Sarigam, Gujarat and also has a wholly owned subsidiary in Belgium.
