Hershey has told retailers it will be taking a double-digit price increase on average across its confection portfolio due to a surge in costs of cocoa, a company spokesperson said Tuesday. The maker of Reese’s Peanut Butter Cups declined to comment on the specifics of the pricing action as discussions with its retail partners are underway.

Hershey told its retail partners it is raising prices by a percentage in the “lower double-digit range” over what its chocolate products cost over the past couple years, a company spokesperson confirmed to CNN. The culprit: high cocoa prices. Bloomberg first reported the increase.

Rising ingredient costs prompted Hershey to raise prices on chocolate products, and the company noted the change is unrelated to tariffs or trade policies.
