Calcium Sulphate Price Trend and Forecast 2026-2027

The US remains the costliest calcium sulphate market, and 2025 widened that gap further, up 9.3% from USD 205.0/MT to USD 224.0/MT. Steady construction demand and tightening gypsum supply did most of the work here. Globally, USD 118.0/MT to USD 130.2/MT, a 10.3% gain, then a seasonal dip to USD 127.5/MT in early 2026 before bouncing back to USD 134.0/MT by June, which is a fairly normal pattern for a construction-linked commodity like this one.

Gypsum, or calcium sulphate if you want the chemistry name, is a naturally occurring mineral made of calcium, sulphur, and oxygen. It comes in synthetic, natural, and flue-gas desulphurisation forms, and grades range from construction-quality material used in wallboard and cement through to agricultural-grade product for soil work and industrial-grade compound for water treatment applications. Cement and construction take the biggest share by far, where it regulates setting time and serves as the raw material for wallboard production, a use that has grown alongside overall building activity in most regions. Agriculture, water treatment, and food or pharmaceutical excipient uses fill out the rest of the demand, each a smaller and fairly stable slice year to year. Gypsum availability, sulphur costs, and construction activity are what really move the number, in roughly that order of importance.

Calcium Sulphate Price Forecast for 2026

The rest of 2026 should bring more measured climbing rather than anything sharp. Construction and infrastructure work has stayed consistent across most regions, gypsum has tightened, and sulphur costs have risen, with both of those propping up the floor. Port inventories are thin in several regions right now, which points to gradual gains rather than volatility through the year's end, barring any real supply shock.

A gypsum supply constraint or a sulphur cost spike is the main upside risk here. A construction slowdown, or someone finally releasing stock they have been sitting on for a while, would ease that pressure and bring the market back below the forecast range.

For the Quarter Ending June 2026

Calcium Sulphate Prices Q2 2026:

• United States: USD 231.0/MT
• China: USD 113.5/MT
• Germany: USD 178.0/MT
• India: USD 152.0/MT

Calcium Sulphate Prices in the United States

USD 231.0/MT, up 5.5%. Construction picked up as the season progressed into warmer months, and gypsum feedstock costs firmed right along with that pickup in activity.

Why did the price of Calcium Sulphate change in Q2 2026 in the United States?

Construction and infrastructure work ramped up through the quarter, lifting demand across most regions of the country. Gypsum feedstock costs rose in step with that demand. Because production capacity in the US remains sufficient, the increase stayed measured rather than sharp, settling near USD 231.0/MT rather than spiking the way it might have in a tighter market.

Calcium Sulphate Prices in China

USD 113.5/MT, up 5.6%. Infrastructure spending drove most of this increase, with feedstock costs adding a bit more on top of that underlying demand.

Why did the price of Calcium Sulphate change in Q2 2026 in China?

Infrastructure and municipal water project spending picked up noticeably this quarter compared to the softer start to the year. Feedstock and energy costs firmed at the same time. Even with the increase, China's scale of production keeps it the cheapest market tracked here by a comfortable margin.

Calcium Sulphate Prices in Germany

USD 178.0/MT, up 5.6%, among the highest levels tracked in this report. Domestic supply stayed tight, and gypsum board manufacturers kept demand firm throughout the quarter.

Why did the price of Calcium Sulphate change in Q2 2026 in Germany?

Domestic supply remained constrained through the quarter, while gypsum board and cement manufacturers kept buying at a steady pace regardless. Port inventories stayed low, and higher raw material and transport costs added further pressure, keeping the market elevated near USD 178.0/MT through most of the period.

Calcium Sulphate Prices in India

USD 152.0/MT, up 5.6%. Both agricultural and construction sector buyers came back into the market this quarter after a quieter start to the year.

Why did the price of Calcium Sulphate change in Q2 2026 in India?

Agricultural fertiliser use and construction activity both picked up through the quarter as the season progressed. Feedstock costs firmed alongside that demand, and the combination pushed prices to USD 152.0/MT by the quarter's end.

For the Quarter Ending March 2026

Calcium Sulphate Prices Q1 2026:

• United States: USD 219.0/MT
• China: USD 107.5/MT
• Germany: USD 168.5/MT
• India: USD 144.0/MT

Calcium Sulphate Prices in the United States

USD 219.0/MT, down 2.2%. Construction slowed seasonally through the colder months, and with production running at sufficient levels, there was not much pressure pushing prices higher.

Why did the price of Calcium Sulphate change in Q1 2026 in the United States?

Winter construction activity typically slows across most of the country, and this year followed that pattern closely. Production stayed sufficient and demand balanced, which kept the market fairly steady even as it eased to USD 219.0/MT ahead of the spring recovery that usually follows.

Calcium Sulphate Prices in China

USD 107.5/MT, down 2.3%. Construction procurement typically slows around the holiday period in China, and that pattern held again this year without much deviation.

Why did the price of Calcium Sulphate change in Q1 2026 in China?

Seasonal construction and infrastructure procurement moderated as it usually does around the holiday period each year. Inventory built up in the prior quarter softened demand somewhat further. The market eased to USD 107.5/MT before picking back up as infrastructure season got underway again in the second quarter.

Calcium Sulphate Prices in Germany

USD 168.5/MT, down 2.3%. Seasonal construction demand softened for the quarter, though the decline stayed limited compared to the size of the gains earlier in 2025.

Why did the price of Calcium Sulphate change in Q1 2026 in Germany?

Construction and gypsum board demand softened somewhat with the season, as it typically does this time of year. Raw material and transport costs stayed elevated though, which kept the market from falling much further than USD 168.5/MT before it turned back up.

Calcium Sulphate Prices in India

USD 144.0/MT, down 2.4%. Agricultural buyers pulled back seasonally, managing pre-season inventory instead of placing fresh orders during this stretch.

Why did the price of Calcium Sulphate change in Q1 2026 in India?

Agricultural fertiliser procurement moderated as buyers focused on working through existing stock ahead of the next cropping season. That reduced urgency eased the market to USD 144.0/MT before demand picked back up again in the second quarter.

Quarterly Calcium Sulphate Price Trends

Six quarters, a familiar arc for this market: a steady climb through 2025 on construction and infrastructure demand, a seasonal pause in early 2026, and a recovery once spring activity got underway. USD 118.0/MT in Q1 2025 to USD 130.2/MT by Q4, eased to USD 127.5/MT in Q1 2026, climbed to USD 134.0/MT by Q2, a net gain of about 13.6% across the entire window. Construction demand cycles, more than anything else, explain this shape, and the pattern has been fairly consistent year over year.

What was Calcium Sulphate Price in 2025?

A firming year overall, driven by expanding construction activity and tightening gypsum supply. USD 118.0/MT at the start, USD 130.2/MT by the fourth quarter, a 10.3% gain across the year. Construction sector growth was the biggest single factor behind that gain, with steady agricultural demand contributing a smaller but still meaningful part. Water treatment applications also added a bit of underlying support, though that segment moves slowly enough that it rarely shows up as a distinct driver in any single quarter.

Calcium Sulphate Prices in the United States in 2025

USD 205.0/MT to USD 224.0/MT, up 9.3%. Construction demand stayed steady all year without much interruption, and feedstock costs climbed alongside it in a fairly predictable way.

Calcium Sulphate Prices in China in 2025

USD 100.5/MT to USD 110.0/MT, a 9.5% increase. Infrastructure demand grew steadily through the year, and feedstock costs firmed in step with that growth.

Calcium Sulphate Prices in Germany in 2025

USD 158.0/MT to USD 172.5/MT, up 9.2%. Domestic supply stayed tight throughout the year, and gypsum board demand held firm the entire time.

Calcium Sulphate Prices in India in 2025

USD 135.0/MT to USD 147.5/MT, a 9.3% gain. Both agricultural and construction demand grew steadily across the year, without either one dominating the other.
