The United States Gunpowder Trade Association (also known as the powder trust or the gunpowder trust) was a trade association of major American powder manufacturers which coordinated pricing for powder from 1872 to 1912. [1] [2] The cartel was dissolved through a Supreme Court ruling in 1912, which found it guilty of violating the Sherman Antitrust Act. [3] [4] [5]
Some of the companies that were part of the cartel included Hazard Powder Company, DuPont, Laflin & Rand Powder Company, Delaware Securities Company, Delaware Investment Company, Eastern Dynamite Company, California Investment Company, and Judson Dynamite and Powder Company. [4]
