LONDON — Unilever and cocoa supplier Barry Callebaut have entered into a long-term agreement in which Barry Callebaut will supply Unilever with approximately 70% of its cocoa and chocolate needs. More specific terms of the agreement were not disclosed.

“Our ice cream category has a significant role to play in Unilever’s sustainable growth model to deliver our ambition of doubling the size of our business whilst reducing our environmental impact,” said Kevin Havelock, president of Unilever’s Refreshment business unit. “Our leadership position has been built on great taste, innovation and increasingly sustainable ingredients. We need partners like Barry Callebaut to help us extend this position and achieve our overall aim.”

Barry Callebaut said it will invest $24 million in its infrastructure in order to develop the capacity necessary to meet Unilever’s needs. The company estimated the necessary upgrades and facility improvements would be completed within 12 months.

On Jan. 17, Barry Callebaut also announced an agreement to supply Grupo Bimbo S.A.B. de CV with up to 32,000 tonnes of chocolate products annually for Bimbo’s domestic market in Mexico.
