North America is a well-established ammonium sulphate market, but remains steady, with the USA an integral part of agricultural production on a large scale, particularly for corn and soybean production. In addition, ammonium sulphate is widely used in the region as a standalone fertilizer and supplement of ammonium nitrate and urea-based fertilizers for acidic soils. Demand further stems from water purification plants and the animal feed sector, supporting supply dynamics
Moderate consumption in agriculture and steady industrial use prop up supply market in Europe. Germany, Belgium and the Netherlands are Western European countries that by-products ammonium sulphate during caprolactam production. Effective fertilizer application and promotions for soil health from the European Green Deal and Common Agricultural Policy (CAP), are driving the demand for Sulfur-rich fertilizers,.
The largest and fastest growing ammonium sulphate supply market is Asia Pacific. China is by far the largest producer with more than 40% of global capacity, mostly as a by-product of synthetic fiber production. India and Southeast Asia are significant importers owing to sulfur-depleted soils and a heavy dependence on nitrogen fertilizers that feed rice and wheat production. Higher investments in chemplants and local fertilizer production sustain long-term supply growth
Supply dependence on byproduct routes and trade volatility limits consistency.
We find that we can only solve a few primary problems with the ammonium sulphate supply chain, primarily involving its reliance on the production of byproduct from the processing of caprolactam and coke oven gas instead of dedicated production. This exposes supply volumes to volatility in upstream sectors like nylon and steel. As a consequence, changes in caprolactam production on a global scale affect the availability of the fertilizer in agricultural plant regions.
Geopolitical tensions and export bans in critical supplier countries have also set off volatility in global prices and availability. They face challenges such as the lack of proliferation of standalone production units and discrepancies in set standard quality levels across suppliers hindering seamless integration in global markets. Supply shortages are particularly damaging in developing countries at critical planting seasons.
Standalone production, green ammonia integration, and precision farming create growth momentum.
To improve reliability, many countries are now targeting dedicated ammonium sulphate production from synthetic ammonia and sulfuric acid, and decoupling supply from caprolactam cycles. Now, this shift opens investment opportunities in emerging economies that are heavily import-dependent.
In addition, the emergence of green ammonia made from renewable hydrogen is likely to profoondly affect nitrogen fertilizer markets over the next ten years. Low-carbon ammonium sulphate, for example, may be a component of sustainability fertilizer systems. The rising adoption of precision agriculture and integrated nutrient management plans also boosts the consumption of sulfur-based fertilizers for localized soil treatment, which in turn supports steadily growing demand.
As the world recovered from COVID-19 pandemic, ammonium sulphate markets (2020 to 2024) were influenced by disrupted regional caprolactam productions during COVID-19 pandemic, supply disruptions owing to Asia export restrictions, and fertilizer prices (driven by energy volatility). Nevertheless demand held up particularly well due to the vital importance of agricultural output and food security measures undertaken in developing areas
In 2025 to 2035 the market will shift from byproduct-based models to systems that have been designed with specific intended purposes in mind. Focus of new entrants will be on energy-efficient synthesis and low-emission processes. At the same time, countries that seek to limit imports of fertilizer will increase downstream integration in the production of nitrogen and sulfur. International trade flows will be streamlined by digital inventory tracking, predictive demand mapping and greater diversification of suppliers’ networks.

The demand for ammonium sulphate supply is still on the rise as the global agricultural, chemical, and polymer sector require more and more dependable nitrogen-bearing compounds for fertilizer mixing as well as for intermediate purposes. Ammonium sulphate (AS) is a type of crystalline salt, mainly used as nitrogen fertilizer, and it is now produced and obtained through chemical byproduct recovery processes.
Ammonium sulphate, based on caprolactam, accounts for highest global market share among production processes owing to the incorporation of this process in nylon-6 production method, the cost-benefit of the process as well as a continuing supply in developed as well as developing regions. This segment plays a significant role in nitrogen supply chains, and helps you achieve industrial circularity, converting caprolactam waste into a valuable agronomic input.
Ammonium sulphate is produced as a by-product of caprolactam plants, used to make nylon intermediates, and increases output could be felt in East Asia and Europe, where demand from their downstream textile and plastic sectors remains healthy. This production route augments supply security at the regional level and mitigates environmental burdens from disposal.
| Production Process | Market Share (2025) |
|---|---|
| Ammonium Sulphate for Caprolactam | 72.4% |
As a result, caprolactam-based production dominates the ammonium sulphate supply market, because ammonium sulphate is produced continuously and can be tailor made to match the solid feed composition going directly into nylon-6 polymer production. Generating about 2.5 to 3 tons of ammonium sulphate per metric ton of caprolactam produced, this route has become a key pillar in nitrogen fertilizer markets.
Chinese, German and South Korean manufacturers extensively utilize this method with integrated production balancing the industrial chemical and fertilizer markets. The dual-product adds more profitability while being sustainable and taking care of chemical effluents from the process.
Its crystalline structure allows it to dissolve easily and be stored, blended, transported in bulk, leading to its popularity in neutralize and acidic dryland soils.
Coke oven gas and gypsum-based methods cater to regional markets or are limited by raw material availability; meanwhile, caprolactam-based AS has a stronghold due to industrial-scale capacity, steady supply, and synergy with synthetic polymer ecosystems.
Strong growth in the ammonium sulphate supply market is driven primarily due to its common use in nitrogenous fertilizers, as well as in industrial chemicals, water treatment, and pharmaceutical applications. With agriculture still taking the lead in global demand, growing population and expanding food security programs are driving fertilizer use across Asia, Latin America and Africa.
Non-durable industrial uses in flame retardants, leather processing and feed additives also are supportive of supply diversification. Producers are also investing in coupled production from caprolactam byproducts, flue gas desulfurization, and coke oven gas streams to meet circular economy and emission-reduction mandates.
