Key Players
Competitive Landscape
Board makers choose gypsum suppliers on purity, moisture and haul distance, and reserve life decides multi-year contracts. The top five producers hold 58 to 63% of global share. Saint-Gobain reported €46.5 billion in group sales for 2025.[1]
Acquisitions and new lines marked 2026. Saint-Gobain completed the PMIM purchase in Vietnam.[5] Etex entered Algeria and invested in Australia.[6][7] Saint-Gobain announced the fourth Bahia line in Brazil.[1]

Board majors buy both quarried and synthetic gypsum. Etex operates 23 sites in Australia.[7] Saint-Gobain holds gypsum, light steel framing, cement board and construction chemicals positions in Vietnam.[5]
Who leads the calcium sulphate market?
The top five producers hold 58 to 63% of global share. Saint-Gobain, USG, Knauf, Etex and Georgia-Pacific figure among the key names on the producer list.
Which calcium sulphate companies have documented positions?
Saint-Gobain added capacity in Brazil and Vietnam.[1][5] Etex added Algeria and upgraded Australian calcination.[6][7]
What should board makers evaluate before approving a gypsum supplier?
Board makers check purity, moisture, haul distance and long-term reserve life. Synthetic gypsum buyers also weigh the closure dates of supplying power plants. Quarries within short haul distance get the first call.
How is calcium sulphate competition expected to change through 2036?
Majors will keep buying local board makers in emerging economies. Quarry ownership will matter more as flue gas gypsum declines.
