Aluminum prices are up 59% from a year ago, and America’s 10% tariffs on the metal are not relieving any headaches at beer and non-alcoholic beverage manufacturers.

The tariffs were originally put in place in 2018, ostensibly to protect domestic aluminum producers. The theory was that China and other foreign producers were “dumping” aluminum into the U.S. at low prices below cost, to capture market share and supposedly drive American producers of aluminum out of business.
