The price changes will impact multiple products in Hershey’s portfolio that are made with chocolate. Among the items expected to increase in price are Hershey Kisses, KitKat, Reese’s and York Peppermint Patties. Hershey’s says price increases typically take around 90 days to take effect.

The price change will be a "low double-digit increase" and affect products across the company's confection portfolio, according to a Hershey spokesperson. Founded in 1894, the Pennsylvania-based company owns over 90 brands including Hershey Kisses, KitKat, Reese's and York.

Hershey is expected to raise its prices for retail customers by double digits. Prices will generally increase between the low teens and 20 percent, The Wall Street Journal reported Tuesday, citing a company official. But the WSJ reports three-quarters of the candy maker’s products should continue to cost $4 or less.
