Copper smelters are relying on by-product sulfuric acid revenues to offset losses from negative concentrate treatment charges. Strong acid prices are supporting smelter profitability, with prices remaining elevated. The trend underscores the key role of sulfuric acid in smelter economics and suggests continued price strength.
Evonik expects Q2 2026 adjusted EBITDA of €600-650mn, up from €509mn a year ago, driven by higher sales volumes and higher prices. Supply chain disruptions affecting Asian competitors provide temporary pricing and availability support; however, the effect is expected to weaken later in 2026 as global shipping stabilizes. Full-year EBITDA outlook raised to €2.0-2.2bn.

Asia
Ammonium sulphate prices in Asia followed a strong upward trend in Q1’26, supported by tightening domestic supply, higher upstream costs, and steady fertilizer demand. The prices were ~1.12 RMB/kg (CFR) in January and ~1.59 RMB/kg (CFR) in March. This quarter’s prices were ~21.07% higher than the previous quarter, while prices increased by ~41.60% from January to March. Supply tightened as export availability from China remained constrained while demand from India and Southeast Asia stayed firm. The Strait of Hormuz disruption reduced ammonia and fertilizer-linked flows, increasing freight risks and limiting import availability, which supported price momentum across the region.
Europe
Ammonium sulphate prices in Europe trended upward during Q1’26 due to elevated ammonia-linked costs and reduced supply flexibility. Natural gas volatility increased upstream ammonia costs, which directly supported ammonium sulphate production costs. At the same time, import availability remained uncertain due to disruptions in Middle East supply chains. About one-third of the global fertilizer trade moves through the Strait of Hormuz, and the sharp fall in vessel movement significantly raised supply concerns across Europe, especially during the pre-season fertilizer demand period.
North America
Ammonium sulphate prices in North America remained firm with a moderate upward trend in Q1’26, supported by steady domestic demand and global nitrogen tightness. Spring planting demand sustained fertilizer consumption, while global trade disruption influenced replacement costs. Although domestic production reduced supply risks compared to other regions, the integrated global fertilizer market transmitted cost pressure from disrupted Middle East flows and higher upstream ammonia and sulphur values.
Analyst Insight
According to Procurement Resource, ammonium sulphate prices are expected to remain firm as long as shipping disruptions and feedstock constraints persist, with any normalization in Hormuz flows likely to ease upward pressure gradually.

Asia
In 2025, the Asian ammonium sulphate market followed a moderately fluctuating but generally balanced trajectory, shaped by conflicting feedstock movements and shifting fertilizer demand. During the first quarter, prices moved within a range as falling ammonia values due to oversupply contrasted with firmer sulfuric acid costs, creating an unsettled cost environment. Demand from the fertilizer sector remained steady and acted as a stabilizing factor. In the second half of the year, the market showed mild fluctuations. Q3 saw brief firmness in China due to higher ammonia costs and temporary supply tightness, though improved operating rates and stable sulfuric acid values later softened the trend. In Q4, Chinese prices increased from around 142 USD/MT (CFR) in October to approximately 160 USD/MT in December, supported by lower operating rates and stronger restocking demand. However, buying resistance at elevated levels led to later consolidation and mild softening.
Europe
European ammonium sulphate prices in 2025 remained largely range-bound with periodic fluctuations. In the first quarter, the market wavered due to lower ammonia prices and firmer sulfuric acid costs, while stable fertilizer demand kept the market balanced. During H2, Q3 remained mostly stable to slightly weak as feedstock costs stayed moderate and agricultural demand softened seasonally. In Q4, the market tracked Asian firmness initially, supported by tighter supply and improved downstream demand, before consolidating as procurement slowed and seasonal holiday closures reduced trading activity.
North America
In North America, ammonium sulphate prices followed a similarly stable-to-firm path in 2025. Q1 reflected wavering trends as lower ammonia costs were balanced by stable sulfuric acid pricing and subtle demand support. Q3 remained largely stable due to adequate supply and cautious purchasing. In Q4, prices rose with constrained caprolactam-grade availability and steady fertilizer demand, before easing slightly toward year-end as buyers shifted to need-based procurement.
Ammonium Sulphate is an inorganic sulphate salt that is derived by the reaction of sulphuric acid with two equivalents of ammonia. It is widely utilised as a fertiliser for alkaline soils. It is also known as an ammonium salt and an inorganic sulphate salt.
