Gypsum Reserves by Country

Two countries multiplied their reported gypsum reserves more than a hundredfold in the same year. The USGS Mineral Commodity Summaries 2019-2026 underpin this page, with reserves representing estimated quantities that can be economically extracted rather than material mined in a given year. The ranking spans 11 countries (9 with reported 2025 values) and 5,597,000 thousand metric tons in listed 2025 reserves.

China (1,800,000 thousand metric tons) leads Thailand (910,000) by nearly two to one. Iran (750,000), the United States (700,000) and Canada and Brazil (450,000 each) fill out a top six in which every step down is visible.

Pakistan's 760,000 absence is more than fifteen times France's 50,000 decline.

Thailand and Pakistan reset the ranking in 2023

Thailand reported 1,700 thousand metric tons from 2019 through 2022, then 910,000 for 2023 — more than a five-hundredfold rise. Pakistan leapt in the same year from 6,000 to 760,000, about a 127-fold increase, and Iran entered the table at 900,000.

Pakistan's 760,000 drops out in 2025

Pakistan held its 760,000 through 2024, then reported nothing for 2025 — the only large holder to exit the latest year. Australia's series is shorter: its last reported value was 340,000 in 2018. Together the two absences remove 1,100,000 thousand metric tons of formerly listed reserves from view.

France is the only 2025 mover

Eight of the nine reported values did not move; France's dip from 350,000 to 300,000 (-14.3%) was the sole change. The United States (700,000), Brazil and Canada (450,000 each), Türkiye (200,000) and India (37,000) have each reported the same reserve figure throughout the 2020–2025 series.

Methodology

Figures come from the USGS Mineral Commodity Summaries 2019-2026, with 2025 values estimated. Units are thousand metric tons, exactly as reported. Empty means the source reported no value; 0 means the source reports zero. The source’s world total, where published, may be rounded, approximate, a lower bound, or a textual estimate, so shares are computed against the sum of the listed countries. Reserves and production are different measures and should not be combined without equalizing units.
