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.

Asia
In China, the average Calcium Sulfate price was ~USD 4,133/MT in the last month of H1’26. Calcium Sulfate market fundamentals remained constrained by abundant desulphurised gypsum from the power sector, which limited pricing power for industrial-grade material. By-product gypsum was increasingly directed toward building materials, chemical products, fertilizers, and soil conditioners, adding to available supply. At the same time, growing wallboard use and new gypsum-product capacity provided demand support. Regional construction activity therefore offset part of the supply pressure, but abundant by-product availability remained the key constraint.
Europe
In Germany, the average Calcium Sulfate price settled at ~USD 4,254/MT in June. European prices were stable during the first quarter before producers introduced increases from April as energy and raw-material costs became more inflationary. Construction volumes were affected by unfavorable weather early in the year, although building activity in several markets remained supported. The cost pressure behind the increases weakened later as crude and energy costs declined following the reopening of the Strait of Hormuz. This reduced some of the upward pressure on energy-intensive calcining and processing costs.
North America
In the USA, the average Calcium Sulfate price was ~USD 4,288/MT in June. Prices faced downward pressure as weaker residential construction reduced wallboard demand. US housing starts fell sharply in May, while wallboard producers also faced excess panel capacity, limiting their ability to sustain higher prices. Domestic gypsum production had also declined, while imports remained important, with Spain, Mexico, and Canada among the principal sources of imported gypsum. Higher freight and raw-material costs added to producer expenses but were insufficient to offset weak construction demand.
Analyst Insight
According to Procurement Resource, Calcium Sulfate prices are likely to remain regionally divided, with construction demand and by-product availability weighing on some markets while energy and freight costs continue to influence European pricing.

Asia
In Asia, the prices of calcium sulfate products continued to increase moderately in Q4’25. Demand from the construction industry and other industrial uses continued to be steady, and the fertilizer industry, particularly the phosphates, continued to contribute to additional demand. Supply of the products was tight in the Asian region, particularly because of the limited availability of gypsum and other raw materials, thereby exerting upward pressure on prices. Production of the products continued to be steady, although there was a drawdown of stocks, particularly because of the local holidays in the Asian region. The Asian market continued to reflect a cautious buying sentiment, with moderate upward pressure on prices, as consumers continued to buy the products while stocks were available.
Europe
In the European market, the price of calcium sulfate showed an increase during the quarter. The feedstock costs, especially the sulfur and gypsum costs went up. This reflected an increase in the costs of the product. Some of the manufacturing units were under pressure due to the high costs of sulfur. This reflected a cautious approach in buying and selling. The demand was stable, but did not show an increase. The exports saw selective buying, especially for competitive pricing. The overall market reflected an increase in the price of the product.
North America
In North America, the prices of calcium sulfate were relatively stable during Q4’25, although prices rose slightly at the beginning of the period. The demand for calcium sulfate was stable from construction, agricultural, and specialty chemical end-use markets. The production of calcium sulfate was carried out normally, and the supply of calcium sulfate was enough to meet the demand. There was a slight impact of increasing energy costs on prices, although this was not enough to cause any fluctuations.
Calcium sulfate is a naturally occurring calcium salt. It is commonly known in its dihydrate form, gypsum- an odorless white power. Calcium sulfate crystals sometimes have a blue, grey, or reddish tinge or can be brick red. It is a common groundwater contaminant, causing hardness that cannot be removed by boiling. Calcined gypsum is used in making tile, wallboard, lath, and various plasters. When gypsum is heated, it loses three-quarters of its water, becoming the hemihydrate commonly known as Plaster of Paris, a widely used construction material.
