What is the market price trend for ferrous sulfate?

The following is the recent market price trend of ferrous sulfate1:

Early March 2025: overall fluctuating downward trend. average price from 1 - 5 March was RMB 312 / ton, average price from 6 - 10 March was RMB 284 / ton, and average price from 11 - 15 March is expected to be RMB 230 / ton.

The price of ferrous sulfate is affected by a number of factors, as follows:

Production process: different production processes to produce ferrous sulfate cost is different, such as sulfuric acid titanium dioxide production process by-product of ferrous sulfate cost is relatively low, and through chemical synthesis and other methods of production of ferrous sulfate cost is higher, the difference in cost will be reflected in the price.

Product purity: the higher the purity of ferrous sulfate, the higher the price is usually, for example, drying ferrous sulfate with content ≥ 98%, the price in Shanghai can be up to RMB 930 / ton, and industrial grade, 91% heptahydrate ferrous sulfate.

Market supply and demand: when market demand is greater than supply, the price rises; conversely, the price falls. For example, in the demand season of water treatment, agriculture and other industries, the price of ferrous sulfate may rise; if the market is oversupplied, the price will be suppressed.

Raw material prices: fluctuations in the price of raw materials for the production of ferrous sulfate will affect its cost, which in turn affects the price. Such as sulfuric acid, iron filings and other raw material prices, will lead to an increase in ferrous sulfate production costs, the price may also rise.

Transportation costs: the transportation costs of ferrous sulfate will also have an impact on the price. The distance between the place of production and the place of sale, the mode of transportation and other factors will lead to different transportation costs, which will make the price of ferrous sulfate in different regions differ.
