American Potash and Chemical Company (sometimes abbreviated as AMPOT) was a large chemical manufacturer in the United States from the 1920s through the 1960s. It produced various chemicals for US industry and the US military. It was bought by Kerr-McGee in 1967, which reformed it into the Kerr-McGee Chemical Corporation (KMCC) around 1970. When AMPOT bought the Lindsay Chemical Company it also got the Rare Earths Facility in West Chicago, Illinois.
