Calcium Sulfate Market Reflects Remarkable Growth at 8.0%

Overview

New York, NY – Jan 01, 2026 – The global calcium sulfate market is projected to grow from USD 2.4 billion in 2024 to around USD 5.2 billion by 2034, expanding at a CAGR of 8.0% between 2025 and 2034, with Asia-Pacific leading the market by accounting for over 39.40% share, equivalent to nearly USD 0.9 billion in revenue in 2024. Calcium sulfate concentrates—including gypsum, hemihydrate, and anhydrite—play a critical role across construction, food and pharmaceuticals, and agriculture, where they are widely used in wallboards, plasters, cement set regulation, food firming and conditioning, calcium fortification, and soil improvement through calcium and sulfur supply.

According to the U.S. Geological Survey, total U.S. gypsum supply in 2024 reached about 42.8 million tonnes, comprising mined, imported, and synthetic sources, with synthetic gypsum alone contributing roughly 37% of quarterly supply in Q4 2024, highlighting its growing importance as a reliable secondary raw material. Regulatory support further strengthens high-purity demand, as calcium sulfate is recognized by the Food and Drug Administration as a multifunctional food additive and standardized in the EU as E516 with a minimum 99.0% purity requirement.

On the supply side, flue-gas desulfurization gypsum from coal plants has gained momentum after the U.S. Environmental Protection Agency endorsed its beneficial agricultural use in 2023, while in India, policy direction from NITI Aayog and handling guidelines issued by the Central Pollution Control Board are improving logistics and compliance, creating a structured pathway for increased synthetic gypsum availability and broader industrial and agricultural utilization.
