Market Analysis for 2025
In 2025, the domestic ammonium sulfate market will rise after the shock surge.
Ammonium sulfate market trend in the first half of 2025 shocks the actors. Ammonium sulfate market price rose in January-February. Demand for downstream composite fertilizer enterprises increased, downstream pellet factories actively replenished, and market trade warmed up. Urea market price rose sharply, favouring the domestic ammonium sulfate market. Ammonium sulfate market price fell in March. Domestic ammonium sulfate market demand was weak, new orders were reduced, and downstream procurement intention was insufficient Ammonium sulfate market price decreased in May. Market demand is limited, weak transaction. In June, the market for ammonium sulfate grew sharply, an increase of more than 20%. Due to geopolitical events, some countries stopped production of urea.
In the second half of 2025, the market for ammonium sulfate is depressed. In July-September, the market price of ammonium sulfate continues to fall. The supply of ammonium sulfate is sufficient, the downstream inquiries are reduced, the purchasing activity is weakened, and the trading atmosphere is light. The export market is poor, enterprise shipments are under pressure, and the ammonium sulfate market is weak. The atmosphere is faint, downstream replenishment on demand, there is resistance to high prices.
According to the K-column chart for the month 2025, the largest increase in ammonium sulfate in the year 2025 is in June, an increase of 20.97%. The largest decrease in the year is in December, a decrease of 10.79%.
Future Market Forecast for 2026
Availability
In recent years, China’s ammonium sulfate production capacity has maintained a growing trend. The total production capacity of ammonium sulfate will reach about 30.5 million tons in 2025, an increase of 12.17% year-on-year. The total output will reach 27.92.4 million tons in 2025 and increase to 34.62 million tons in 2027. The growth is mainly due to the rapid growth in the commissioning and by-production capacity of large-scale capsulamide units. In 2023-2025, there are about 34 ammonium sulfate proposed units in China, with a total production capacity of 4.4 million tons / year, of which capsulamide grade accounts for 88%.

China’s ammonium sulfate production capacity is expected to continue to increase in 2026. The compound growth rate is expected to be 4.40% over the next five years, which is slower than in the past five years. Environmental protection policies and “dual carbon” targets will drive SME production capacity and expand the advantages of leading enterprises.
Export situation
In January-November 2025, China’s total ammonium sulfate exports reached 1936 million tons, an increase of 4.01 million tons compared to the same period last year, an increase of 26.1% year-on-year, with total exports of $2.995 billion, an increase of 31% year-on-year, and the total annual export volume is expected to reach 21 million tons. In January-November 2025, China’s main exporters of ammonium sulfate are Brazil, Vietnam, Myanmar, Indonesia and Turkey.
China is a major supplier of ammonium sulfate worldwide, with increasing market share and influence. Combined with the continued release of China’s ammonium sulfate production capacity, exports are expected to continue to grow in 2026, but the growth rate will be somewhat slower than before. There is a problem of soil sulfur deficiency in the Americas, and demand for ammonium sulfate is expected to continue to grow, and Brazil may maintain the status quo as the largest export destination. The maturity of extrusion pellet technology will also help ammonium sulfate exports.
Demand situation
In 2025, China’s demand for ammonium sulfate is expected to reach 10.564 million tons, with agricultural composite fertilizers and industrial applications being the main growth points. Agriculture: accounting for 65%-70%, and the demand for economic crops such as tobacco and tea will grow by an average of 3.5%-4.2% per year. Industrial: accounting will increase from 22% to 30%, and the demand for new energy batteries (lithium battery positive-pole materials) and rare earth mining is strong.
Demand for ammonium sulfate in China is expected to grow steadily in 2026, with agriculture and industry being the main drivers.
Agricultural demand: increased food production drives the demand for nitrogen fertilizer. The increase in food production directly pulls the demand for ammonium sulfate as nitrogen fertilizer.
Industrial demand: Multi-industry applications are expanding. Antibiotics and vitamin production demand is increasing, driving the application of ammonium sulfate in the pharmaceutical field, and the demand for new energy batteries and rare earth mining is increasing.
Summary and outlook
In summary, the overall market situation for ammonium sulfate in 2025 is good. Supply is sufficient, demand is mainly agricultural, and industrial applications are growing significantly. Technically, green production technology and high purity products are trends. In terms of policy, environmental standards are tightened, but agricultural subsidies may continue.
Ammonium sulfate market is expected to remain optimistic in 2026. The market is expected to have a loose supply, and exports are still the main driver of growth, but prices may fluctuate under the influence of environmental protection policies. Ammonium sulfate production capacity is expected to continue to grow, but the growth rate is slowing down, mainly affected by the pace of production of capsulamide devices.
