Chocolate lovers might not want any kisses from Hershey anytime soon.

Pennsylvania’s own chocolate maker Hershey has banned imports into the U.S. of British-manufactured Cadbury chocolate, among others.

Hershey blocked imports of Cadbury chocolate products into the U.S. after a settlement between the Hershey Company and Let’s Buy British Imports, one of the country’s top distributors of popular food brands from the UK, Australia and South Africa. Hershey claimed that the imports infringed on trademarks because the packaging is similar to Hershey products and could be misleading to consumers.

Other products that have been banned include Yorkie chocolate bars, Toffee Crisps, Maltesers, and British Ki-Kat bars.

While Hershey has the license to produce Cadbury chocolate in the U.S., the products have different recipes, resulting in a different taste.

“Chocolate in Britain has a higher fat content; the first ingredient listed on a British Cadbury’s Dairy Milk (plain milk chocolate) is milk. In an American-made Cadbury’s bar, the first ingredient is sugar,” The New York Times writes.

This ban has chocolate lovers up in arms on social media. Displeased consumers have started a  #BoycottHershey hashtag as well as a petition on MoveOn.org.

21st century capitalism: Someone does it better than you? Don't compete with them, ban them. Shame on Hershey's. #BoycottHershey

If you're THAT worried about your product, don't you think you should be innovating rather than blocking imports? #boycotthershey
