The global ammonium sulphate supply market is set to witness significant growth over the next decade, driven by the need for sustainable agriculture practices and improved crop yields. Valued at USD 3,706.1 Million in 2025, the market is forecasted to reach USD 7,497.5 Million by 2035, expanding at a robust CAGR of 7.3%. Increasing emphasis on sulfur-deficient soil treatment and regulatory backing for balanced nutrient applications are key growth drivers across multiple regions.
Caprolactam-based production dominates the ammonium sulphate supply market, accounting for 72.4% of global share in 2025, due to its integration with nylon-6 manufacturing, cost efficiency, and sustainable byproduct recovery. Widely adopted in China, Germany, and South Korea, this method ensures continuous output, supply stability, and supports circular economy goals—making it the preferred choice over coke oven gas and gypsum-based alternatives.

- Byproduct-Based Production: An industry-wide shift is underway toward producing ammonium sulphate from industrial byproducts, aligning with circular economy goals and reducing waste.
- Technological Advancements: Improvements in granulation and coating technologies are ensuring uniform distribution, reducing nitrogen volatilization, and improving fertigation compatibility.
- Precision Agriculture Integration: Growing adoption of granular and blended formulations makes ammonium sulphate highly compatible with modern precision farming tools and systems.
Key Takeaways of the Report:
- The global ammonium sulphate market is projected to grow at a CAGR of 7.3% from 2025 to 2035.
- United States leads with a CAGR of 7.6%, followed by South Korea (7.5%), and the European Union (7.3%).
- Increasing soil sulfur deficiency is compelling governments and farmers to adopt sulfur-based fertilizers, with ammonium sulphate emerging as a cost-effective solution.
- Government support and policy alignment in regions like the EU (Common Agricultural Policy), UK (Environment Act 2021), and Korea (Korean New Deal) are fostering market expansion.
- Eco-friendly product formulations and improved supply chains are enhancing product adoption, especially in regions with salt-sensitive crops like Japan.
Caprolactam-Based Production Leads the Market
Caprolactam-based production accounts for 72.4% of the global ammonium sulphate market in 2025, making it the dominant process due to its integration with nylon-6 manufacturing. It offers continuous output, cost efficiency, and supports circular manufacturing by converting chemical waste into valuable fertilizer.
Industrial Integration Drives Stability
Used widely in China, Germany, and South Korea, this method ensures stable supply and supports both fertilizer and polymer sectors. Compared to coke oven gas and gypsum-based methods, caprolactam production offers scalable output, steady raw material flow, and better alignment with sustainable, large-scale industrial systems.
Regional Market Outlook:
United States:
A stronghold in the global ammonium sulphate market, the U.S. is seeing demand driven by crop fertilization needs in sulfur-deficient soils, particularly for corn, wheat, and soybeans. Supportive EPA guidelines and byproduct recovery from industries like coke and caprolactam are fueling domestic production.
United Kingdom:
The UK market is being reshaped by sustainability regulations under the Environment Act 2021. With increasing sulfur deficiency and environmental concerns, ammonium sulphate is being integrated into balanced nutrient programs for cereals, rapeseed, and grasslands.
European Union:
Nutrient efficiency mandates under CAP and the Farm to Fork Strategy are propelling growth in Germany, France, and Poland. Industrial byproduct utilization and formulation innovation for uniform fertilizer application are central to the EU market’s progress.
Japan:
Japan’s ammonium sulphate demand is driven by rice farming, horticulture, and greenhouse crops. Government initiatives promoting food self-sufficiency and chloride-free fertilizers are creating fertile ground for innovation in slow-release and organic formulations.
South Korea:
With rice cultivation and protected agriculture at the forefront, South Korea is witnessing strong adoption of ammonium sulphate in compound and urea blend fertilizers. The government’s sustainable agriculture programs and advanced domestic production facilities are adding momentum to the market.
