Hydrofluoric acid is produced in South Africa by a few companies, including Sasol and Solvay Fluorides. Sasol is a large integrated energy and chemicals company that produces hydrofluoric acid as part of its chemical operations, while Solvay Fluorides is a subsidiary of the international chemicals company Solvay, which also produces hydrofluoric acid in South Africa. Other smaller chemical companies in South Africa may also produce hydrofluoric acid, but Sasol and Solvay Fluorides are the main manufacturers of the chemical in the country.
