Ammonium Sulphate Price Trend and Forecast 2026: Latest Global Market Analysis and Industry Outlook

 

According to ChemAnalyst, the global Ammonium Sulphate Price environment through 2026 has been dominated by a broadly synchronized second-quarter rally, with North America surging 20.14% and South Korea an extraordinary 40.38% quarter-over-quarter as strong spring fertilizer demand, cracker run-rate cuts, and tightened export availability pushed prices sharply higher across virtually every major region, even as spot pricing softened toward June as post-planting demand eased. Ammonium sulphate (AS) is an inorganic salt with several commercial uses, generally produced through three different processes: as a byproduct of caprolactam production, by combining anhydrous ammonia and sulphuric acid in a reactor, or by reacting ammonia recovered from coke oven gas with sulphuric acid. Its primary use is as a soil fertilizer given its nitrogen and sulphur content, while it also serves in flame retardant chemicals owing to its capability to increase the combustion temperature of materials. This report examines the Ammonium Sulphate Price Trend across North America, Asia-Pacific, and Europe, unpacks the feedstock and demand dynamics behind recent price movements, and offers a forward-looking outlook for the remainder of 2026.

Understanding Ammonium Sulphate as a Commodity

Ammonium Sulphate's distinctive multi-pathway production structure — as a byproduct of caprolactam manufacturing, through direct synthesis from ammonia and sulphuric acid, or via coke-oven gas recovery — gives the market a genuinely unusual supply dynamic compared to most conventional fertilizer commodities. Because a substantial share of global supply emerges as a byproduct rather than dedicated primary production, Ammonium Sulphate availability is often tied to unrelated industrial activity, such as caprolactam and coke-oven operating rates, rather than fertilizer-specific investment decisions.

This byproduct-heavy supply structure means the Ammonium Sulphate Price is shaped by an unusually broad set of factors: agricultural fertilizer demand and planting seasonality on one side, and caprolactam production economics, coke-oven utilization, and ammonia and sulphuric acid feedstock costs on the other. Demand for nutrient-rich food, development in the agriculture industry, and receding arable land are widely cited as major growth drivers for the Ammonium Sulphate market over the medium term, with agriculture representing the largest end-consumer segment globally. At the same time, volatility in raw material prices — particularly ammonia and sulphuric acid — remains one of the primary hindrances to stable, predictable market growth, a dynamic that has been on full display throughout 2025 and 2026.

North America: Strong Spring Demand Drives a Sharp Second-Quarter Surge

In the United States, the Ammonium Sulphate Price Index rose 20.141% quarter-over-quarter in the second quarter of 2026, buoyed by strong spring fertilizer demand, with the average price at approximately USD 511.00 per metric ton, reflecting balanced supply conditions. The Ammonium Sulphate Spot Price eased as import arrivals remained steady and domestic sellers offered prompt cargo discounts, while the production cost trend showed mixed pressures as lower ammonia costs offset firmer sulphuric acid-based inputs. The demand outlook remained muted post-planting, with distributors delaying purchases until side-dress and autumn programs, even as export diversion effects and ample Gulf inventories kept offers under pressure, with major Midwestern plants operating at steady run-rates, limiting supply shocks while supporting transactional liquidity in the merchant market.

This followed a first quarter of 2026 that had seen the US index rise 12.8559% quarter-over-quarter, prompted by import tightness, with the average price at approximately USD 436.00 per metric ton in Florida hubs, as Gulf terminal inventories fell and buyers bid for constrained cargoes, while war-related feedstock disruptions increased ammonia and sulfur shipment risk, elevating production costs and caution. Pre-plant agricultural nominations and increased distributor purchasing had elevated near-term offtake ahead of the spring application period, with exporters delaying shipments and constrained domestic byproduct output supporting a bullish market tone. This built on a fourth-quarter 2025 decline of 5.12% quarter-over-quarter, reflecting weak demand, as ample domestic production and elevated inventories led suppliers to discount prompt cargoes, following a third-quarter 2025 decline of 18.91% quarter-over-quarter reflecting oversupply pressure, as sustained domestic production and import arrivals had created oversupply amid a seasonal lull after spring planting. By June 2026, US Ammonium Sulphate prices stood at approximately USD 486.00 per metric ton.

Asia-Pacific: South Korea, China, and India See Dramatic Cracker-Driven Gains

South Korea saw its Ammonium Sulphate Price Index surge 40.38% quarter-over-quarter in the second quarter of 2026, due to cracker run-rate cuts, with the average price at approximately USD 270 per metric ton, per regional FOB assessments. Spot price volatility reflected shifting export inquiries and Chinese cargoes pressuring Korean offers, while the production cost trend showed upward pressure from LNG and sulphuric acid premiums recently. The demand outlook remained seasonally strong for Southeast Asian blenders ahead of planting season, even as ample domestic byproduct supply from steady caprolactam and coke-oven operations increased spot availability, pressuring offers, with subdued export enquiries from Southeast Asia and India reducing buying urgency and competitive Chinese cargo availability limiting producer pricing power despite occasional sulphuric acid cost upticks.

China saw its Ammonium Sulphate Price Index rise 24.96% quarter-over-quarter, reflecting tightened export availability, with the spot price easing in June as import inquiries weakened across core Asian buying. India saw its index rise 32.10% quarter-over-quarter, driven by restocking activity, even as exporters pushed lower spot price offers from East Asia, pressuring landed parity swiftly. This followed a first quarter of 2026 that had seen South Korea's index rise a more modest 3.59% quarter-over-quarter, reflecting export tightness, with the average price at approximately USD 192.33 per metric ton, as export availability had tightened after caprolactam maintenance and byproduct reductions reduced merchant supply, while rising LNG and sulphuric acid feedstock costs increased production expenses. By June 2026, South Korean Ammonium Sulphate prices stood at approximately USD 258.0 per metric ton, Chinese prices at USD 238.0 per metric ton, and Indian prices at USD 350.0 per metric ton.

Europe: Germany Sees Sustained Seasonal Demand-Driven Firmness

In Germany, the Ammonium Sulphate Price Index rose 24.11% quarter-over-quarter in the second quarter of 2026, reflecting stronger seasonal demand, with the average price at approximately USD 394.67 per metric ton as reported locally. The spot price remained volatile, with limited spot availability and seller offers sustaining firmness, while the production cost trend showed mixed pressures as falling ammonia offset rising sulphuric acid, compressing margins. The demand outlook remained seasonal, with agricultural top-dressing support but post-spring consumption gradually easing, even as balanced inventory and stable logistics limited abrupt directional shifts, with thin Hamburg stocks and nearby export demand absorbing surplus while integrated plants maintained operational rates.

This followed a first quarter of 2026 that had seen the German index rise 12.37% quarter-over-quarter, driven by tighter feedstock, with the average price at approximately USD 318.00 per metric ton, as exporters limited sales, keeping availability constrained with firm offers, while war disruptions reduced ammonia shipments, tightening upstream feedstock availability and raising production costs across the region. Higher gas prices had raised ammonia costs, prompting producers to limit runs and prioritize contracted shipments, with export enquiries from Central Europe absorbing volumes and tightening domestic spot supply ahead of spring application. This built on a fourth-quarter 2025 increase of 5.07% quarter-over-quarter, driven by ammonia increases, following a third-quarter 2025 rise of just 0.5% quarter-over-quarter, reflecting tighter supply conditions as autumn applications and compliance-driven buying had accelerated restocking amid river low water and port congestion constraining inland logistics.

Key Drivers Behind the 2026 Ammonium Sulphate Price Trend

Bringing the regional analysis together, several structural themes are shaping global Ammonium Sulphate pricing through 2026:

1. Byproduct supply linkage to caprolactam and coke-oven operations. Because a substantial share of global Ammonium Sulphate supply emerges as a byproduct of caprolactam production and coke-oven gas recovery, cracker run-rate decisions and maintenance schedules — as seen dramatically in South Korea's second-quarter surge — have an outsized effect on availability independent of direct fertilizer demand trends.

2. Ammonia and sulphuric acid feedstock cost divergence. Across nearly every region and quarter analyzed, ammonia and sulphuric acid costs have frequently moved in opposite directions, creating a genuinely mixed production cost trend that has periodically compressed producer margins even during periods of firm pricing.

3. Seasonal planting and side-dress application cycles. Spring pre-plant nominations and side-dress fertilizer programs have repeatedly driven concentrated demand surges across North America and Europe, with post-planting demand lulls just as reliably triggering subsequent price softening.

4. Geopolitical disruptions affecting ammonia shipments. War-related feedstock disruptions have repeatedly increased ammonia and sulfur shipment risk, elevating production costs and caution across North America and Europe throughout the first half of 2026.

5. Export diversion and competitive Asian cargo flows. Competitive Chinese cargo availability has repeatedly pressured South Korean and other Asia-Pacific pricing, while export diversion effects have periodically supported Gulf Coast inventory positions in the United States.

6. Regional logistics and port congestion. River low water levels, Gulf berth congestion, and inland waterway disruptions have repeatedly tightened physical availability and elevated distribution costs across both North America and Europe at various points throughout 2025 and 2026.

Outlook: What to Expect Going Forward

Looking ahead, the Ammonium Sulphate Price Trend is likely to see near-term moderation following the dramatic second-quarter 2026 gains before autumn restocking provides renewed support. In North America, the price forecast indicates modest near-term softening before seasonal restocking supports firmer late-summer pricing. In Asia-Pacific, South Korea's forecast expects moderate easing then stabilization as seasonal demand and inventories normalize. In Europe, the German forecast suggests near-term softness before autumn restocking, structural supply and seasonal dynamics reassert themselves.

For buyers, this environment underscores the importance of monitoring caprolactam and coke-oven operating rates alongside ammonia and sulphuric acid feedstock markets closely, given how directly and repeatedly these factors have driven Ammonium Sulphate price movements across multiple regions throughout 2025 and 2026. Buyers in agricultural fertilizer applications should factor continued seasonal volatility into procurement planning, particularly given the demonstrated capacity for the market to swing dramatically between planting-season tightness and post-application softness. Producers and distributors, meanwhile, will need to continue navigating the tension between byproduct-driven supply dynamics and genuinely seasonal agricultural demand patterns.

Why Track the Ammonium Sulphate Price Closely

Given its essential role as a nitrogen and sulphur soil fertilizer, its distinctive byproduct-linked supply structure tied to caprolactam and coke-oven industrial operations, and its demonstrated sensitivity to both agricultural seasonality and unrelated industrial production decisions, Ammonium Sulphate is a commodity where pricing dynamics can shift dramatically and sometimes counterintuitively, as illustrated by South Korea's extraordinary 40.38% quarterly surge during the second quarter of 2026. For fertilizer distributors, agricultural retailers, caprolactam producers, and procurement teams, staying current on real-time regional pricing, byproduct supply trends, and the underlying seasonal and feedstock factors behind each price movement is essential for effective contract negotiation, inventory planning, and cost management.

Continuous monitoring of the Ammonium Sulphate Price — tracked by region and updated regularly — combined with a clear understanding of the byproduct supply, feedstock, and seasonal demand factors driving each market, gives buyers and sellers the context needed to navigate a genuinely unusual fertilizer commodity market shaped as much by unrelated industrial production decisions as by traditional agricultural supply-demand fundamentals. As 2026 progresses, expect the Ammonium Sulphate Price Trend to keep reflecting this balance between caprolactam and coke-oven byproduct supply, ammonia and sulphuric acid feedstock costs, and steady, seasonally-driven structural demand from the global agricultural sector.
