Global ammonium sulfate market grows by $5.7 billion over a decade; agriculture in multiple countries drives demand upward.

Recently, "Chemical & Materials" released a special industry research report, systematically reviewing the current status of the global ammonium sulfate industry and providing quantitative forecasts for industry scale, segmented structure, country-specific demand, and future development trends from 2025 to 2035. Data shows that the global ammonium sulfate market is steadily rising, with rigid agricultural demand as the core driver. Products are iterating towards granulation, specialization, and green efficiency enhancement, while regions such as the US, Europe, Japan, and South Korea exhibit differentiated growth rhythms due to their specific agricultural characteristics.

I. Total Volume Measurement: Market Expands by $1.2 Billion in Ten Years, Rising Steadily in Two Stages

According to the report, the global ammonium sulfate market size will be $4.5 billion in 2025 and is expected to increase to $5.7 billion by 2035. This represents a cumulative increment of $1.2 billion over ten years, an overall increase of 26.7%, and a compound annual growth rate (CAGR) of 2.4%. Rising rigid grain demand, increased penetration of nitrogen-sulfur dual-effect fertilizers, and expanded applications in industrial and fine chemicals jointly support the industry's expansion to 1.27 times its original volume over the decade.

Market growth presents distinct phased characteristics:

1. 2025—2030: The market grows from $4.5 billion to $5 billion, an increment of $500 million, accounting for 41.7% of the total ten-year increment. The implementation of global food security strategies, the transformation of agricultural intensification, and the volume release of rigid sulfur fertilizer demand drive chemical and agricultural enterprises in various regions to add new capacity to match the fertilizer needs of field planting.

2. 2030—2035: The market size rises from $5 billion to $5.7 billion, adding $700 million, which accounts for 58.3% of the total increment. The comprehensive implementation of sustainable agriculture and precision fertilization, along with soil improvement and quality enhancement of economic crops, spurs demand for specialty fertilizers, becoming a new engine for industry growth in the mid-to-late period.

II. Segmented Landscape: Granular Products and Agricultural Applications Dominate the Industry

1. Product Form: Granular Ammonium Sulfate Becomes the Market Choice

Compared to crystalline and liquid types, granular ammonium sulfate held a 52% market share in 2025, ranking first. The product offers excellent fluidity, is resistant to caking, and is suitable for mechanized fertilizer spreading and large-scale storage and transportation, aligning with the global trend of popularizing agricultural machinery in field farming. With the continuous promotion of variable rate fertilization equipment, the advantages of granular ammonium sulfate will be further consolidated.

2. Application Structure: Agricultural Demand Supports 70% of the Market

In 2025, the agricultural sector accounted for 72% of total ammonium sulfate consumption, serving as the industry's fundamental base; the remaining market consists of industrial raw materials, feed additives, and other segmented demands.

3. Raw Material Sources: By-product Recovery and Chemical Synthesis are Two Major Production Paths

Currently, the global supply of ammonium sulfate raw materials relies primarily on two process routes: by-product recovery from caprolactam units and chemical synthesis. It is also an important category for the resource utilization of chemical by-products domestically.

III. Industry Pros and Cons: Multiple Positive Factors Drive Expansion, While Substitution and Environmental Protection Form Developmental Constraints

Positive Support

Global population growth forces increased grain production. The popularization of intensive planting, the implementation of balanced fertilization concepts, and the long-term upward trend in demand for nitrogen-sulfur combined fertilizers continue to raise the ceiling for ammonium sulfate demand.

Constraining Factors

Product substitution competition exists from unitary nitrogen fertilizers like urea; environmental policies are becoming stricter globally, with ammonia control and soil acidification management raising production thresholds; fluctuations in upstream raw materials and bottlenecks in existing capacity periodically limit industry expansion.

IV. Three Long-term Development Trends: Green, Customized, and High-end Specialty Fertilizers Become the Main R&D Focus

1. Accelerated Implementation of Green Low-load Products: The normalization of green planting drives the volume release of environmentally friendly ammonium sulfate, making efficiency-enhancing modified products a focus of corporate R&D;

2. Customized Formula Fertilizers Supporting Modern Agriculture: The popularization of smart agriculture equipment such as GPS variable rate fertilization and soil monitoring creates development opportunities for on-demand customized formula ammonium sulfate;

3. Specialty Slow-release Products Tapping into High Value-added Crops: The expansion of economic crop planting such as fruits, vegetables, and traditional Chinese medicinal materials drives the rapid volume release of new specialty ammonium sulfate products featuring slow/controlled release, coating, and inhibitor additions. Enterprises are leveraging granulation, coating, and additive technologies to lay out in the high-end differentiated track.

The report mentions that industry participants include large fertilizer groups, fine chemical enterprises, and comprehensive agricultural service providers. Technical transformation for cost reduction, new product development, green production, and segmented customization are key to building core competitiveness.

V. Divergence in Country Growth Rates: North America Leads in Growth, Japan and South Korea Rely on Precision Agriculture for Steady Growth

The report discloses the 2025—2035 CAGRs for various countries: USA 2.8%, Mexico 2.6%, Germany 2.2%, France 2.1%, UK 1.9%, South Korea 1.8%, Japan 1.7%. Regional agricultural models determine demand logic:

· USA, Mexico (North America): Large-scale US farms and precision agriculture systems drive demand for soil improvement fertilizers; Mexico's agricultural export industrialization is accelerating, opening up agricultural material increments through North American trade dividends.

· Germany, UK, France (Europe): Germany's stringent environmental standards drive the R&D and export of green efficiency-enhancing fertilizers; France's diverse cropping creates demand for high-end agricultural ammonium sulfate; the UK relies on refined nutrient management to optimize fertilizer application structures.

· Japan, South Korea: The popularization of facility horticulture and high-standard refined farmland drives steady growth in demand for high-purity specialty ammonium sulfate.
