Ferrous Sulfate Market Outlook:
Ferrous Sulfate Market size was over USD 2.42 billion in 2025 and is projected to reach USD 3.55 billion by 2035, growing at around 3.9% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of ferrous sulfate is evaluated at USD 2.5 billion.
The ferrous sulfate market is expanding due to the rising demand for fertilizers, water treatment, and pharmaceuticals. Ferrous sulfate is essential in agriculture for restoring plant iron deficiency, boosting crop yields, and increasing soil quality. It works especially well to treat chlorosis, a disease brought on by an iron shortage that causes growth retardation and yellowing of the leaves. The necessity for high-quality agricultural products and the growing emphasis on sustainable farming methods fuel the ferrous sulfate market in this industry. According to WHO estimates, anemia affects 269 million children aged 6 to 59 months and half a billion women aged 15 to 49 globally. Anemia affects 106 million women and 103 million children in Africa and 244 million women and 83 million children in South-East Asia. These two regions are the most afflicted.
The increasing demand for clean water, especially in the water treatment sector, drives the ferrous sulfate demand in the market. Water supplies now contain more pollutants as a result of increased industrialization and urbanization. An essential coagulant for purging water of pollutants and impurities so that it is fit for industrial and human consumption is ferrous sulfate. The market's expansion has also been significantly fueled by government legislation requiring clean water standards.
