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.

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

Hershey, the maker of Reese’s, Whoppers, barkThins and other chocolate candies, said Wednesday that it will be raising U.S. retail prices later this fall. In some cases, pack sizes will get smaller; in others, list prices will rise. The average price increase will be in the low double-digit percentages.
