United States Gunpowder Trade Association
From Wikipedia, the free encyclopedia
The United States Gunpowder Trade Association (also known as the powder trust or the gunpowder trust) was a trade association of major American gunpowder manufacturers which coordinated pricing for gunpowder 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]
