Sulfuric acid prices rose sharply through the first half of 2026 before retreating from their mid-year peak as supply conditions loosened. Weak downstream demand has contributed to the easing, though the commodity remains a critical revenue buffer for copper smelters facing squeezed processing margins. The price trajectory reflects the interplay between by-product supply dynamics and broader industrial demand.
China's 98% smelting sulfuric acid price eased over the week as spot trading weakened and recovering supply added pressure. Elevated sulfur and metal ore costs provided partial support, but the market faces further downside as lower-priced regional supplies increase competitive pressure.

Stay updated with the latest Aluminium Sulfate prices, historical data, and tailored regional analysis
In China, the average price of Aluminium Sulfate was ~USD 177/MT (FOB) in the last month of Q2’26. Chinese conditions remained competitive during Q2 as ample domestic production and strong supplier competition limited pricing power. Market movement varied by grade and location, with high-purity material commanding stronger offers than standard industrial and water-treatment grades. Aluminium Sulfate in India was assessed at an average of ~USD 265/MT (CIF) in June. Indian values remained higher because of freight, import and handling costs, while municipal water treatment, paper manufacturing and industrial processing maintained regular demand. The average price of Aluminium Sulfate in the USA came in at ~USD 332/MT (CIF) in June, with Canada on par at the same level. North American conditions were firmer as aluminium-related inputs, inorganic chemical costs, energy and transportation expenses increased replacement costs. U.S. basic inorganic chemical producer prices rose 1.6% month on month in May, reinforcing cost pressure on regional chemical manufacturers. Water-treatment demand remained steady, but sufficient supply prevented a sharper increase.
Analyst Insight
According to Procurement Resource, aluminium sulfate prices are expected to remain stable to slightly firm, supported by treatment demand and operating costs while competitive Asian supply limits stronger gains.

Aluminium sulfate prices followed a firm trend in Q1 2026 as feedstock and logistics pressure outweighed moderate downstream demand. In Asia, India recorded a 5.24% increase from Q4 2025 to Q1 2026, while prices rose 6.99% from January to March 2026. The increase was supported by higher sulfuric acid-related cost pressure, steady demand from water treatment and paper applications, and freight uncertainty linked to the Iran war. In Europe, the United Kingdom showed a more moderate rise, with aluminium sulfate prices increasing 4.02% from Q4 2025 to Q1 2026 and 5.33% from January to March 2026. Demand from municipal water treatment and industrial effluent treatment stayed stable, while energy and logistics costs kept producers cautious. In North America, the USA posted the strongest increase, with prices rising 15.53% from Q4 2025 to Q1 2026 and 12.60% from January to March 2026. The sharper movement reflected stronger cost pass-through, steady water-treatment demand, and broader chemical logistics pressure.
Aluminium Sulfate is a water-soluble white crystalline solid, and it is primarily used as a coagulating agent in the purification of drinking water and sewage treatment plants. Its anhydrous form occurs naturally as a millosevichite mineral found near volcanic sites. Aluminium Sulfate usually occurs in its hydrate form, mainly as hexadecahydrates or octadecahydrates. Aluminium Sulfate is often referred to as alum which has been used as a flocculating agent since immemorial. The alum is a hydrated aluminium sulfate salt with a monovalent cation often substituted by potassium or ammonium.

Alum schists (a type of metamorphic rock) are a mixture of iron pyrite, aluminium silicate, and various bituminous substances. These are roasted, and during the process, the sulfuric acid obtained reacts with clay to form a product mixture containing aluminium sulfate. The mixture is subjected to further treatment to remove the impurities. The mixture is mixed with water and allowed to stand for water-soluble impurities to separate. Additionally, it is subjected to evaporation so that iron sulfate crystals separate, leaving the desired aluminium sulfate.
