Swiss chocolate producer Barry Callebaut has seen quarterly sales jump almost 22% thanks to its outsourcing deals with the likes of Hershey and Nestlé.

The company posted a 21.9% rise in first-quarter sales to CHF1.4bn (US$1.3bn) for the three months to 30 November.

Callebaut also pointed out that part of the rise in revenue stemmed from the passing on of higher raw material prices to its customers.

CEO Patrick De Maeseneire said Callebaut had "clearly strengthened our leadership position" in the business-to-business chocolate sector.

Callebaut saw European sales volumes grow by 11.5% to over 240,000 tonnes, driven by increased demand from industrial and artisanal customers. Sales volumes in the Americas rose 12.9% thanks to Callebaut's outsourcing deals.
 
However, Callebaut saw volumes in Asia and its rest of the world division fall 6.6% with volumes hit by the sale of its Chocosen subsidiary in Senegal last year and capacity constraints in Asia.
