Domestic gypsum resources are adequate but unevenly distributed. Large imports from Canada augment domestic supplies for walboard manufacturing in the United States, particularly in the eastern and southern coastal regions. Imports from Mexico supplement domestic supplies for wallboard manufacturing along portions of the U.S. western seaboard Large gypsum deposits occur in the Great Lakes region, the midcontinent region, and several Western States Foreign resources are large and widely distributed, 81 countries produced gypsum in 2016 Substitutes: In such applications as stucco and plaster, cement and lime may be substituted for gypsum; brick glass, metalic or plastic panels, and wood may be substituted for wallboard. Gypsum has no practical substitute in the manufacturing of portiand cement Synthetic gypsum generated by various industrial processes, including FGD of smokestack emissions, is very important as a substitute for mined gypsum in wallboard manufacturing, cement production, and agricultural applications (in descending order by tonnage). In 2016, synthetic gypsum accounted for approximately 50% of the total domestic gypsum supply Estimated NA Not available The standard unt used n the U S walboard industry is square feet, multiply square feet by 9 29 x10 to convert to square meters Source The Gypsum Association Data refer to the amount sold or used, not produced From domestic crude and synthetic Defined as orude production total synthetic reported used imports-exports Defined as imports-exports See AceendsCfor resource and reserve definitions and information concerming data sources U.S. Geological Survey, Mineral Commodity Summaries, January 2017

Approximately 7 2 million tons of gypsum was used in cement production agricultural applications, and small quanbties of high-purity gypsum, used in a wide range of industrial processes accounted for the remaining tonnage. At the beginning of 2016, the production capacity of operating in the United States was about 33 billion square feet per year.

The recycled gypsum was used primarily for agricultural purposes and feedstock for the manufacture of new wallboard. Other potential markets for recycled gypsum include athletic field marking, cement production as a stucco additive, grease absorption, sludge drying, and water treatment ImportSourcet2012-15): Mexico, 43%; Canada, 3296, Spain, 25%, and other, less than 1%.

Events, Trends, and Issues: U.S. gypsum production increased slightly compared with that of 2015. Apparent co sumption als creased by 5% eempared with that of 2015 The words leading gypsum producer, China. more than eight times the amount produced in the United States Iran, ranked second in world production, supplied much of the gypsum needed for construction in the Middle East Spain, the leading European producer ranked seventh in the world and supplied crude gypsum and gypsum products to much of Western Europe Increased use of wallboard in Asia, coupled with new gypsum product plants, spurred increased production in that region. As wallboard becomes more widely used in other regions, worldwide production of gypsum is expected to increase Demand for gypsum depends principally on the strength of the construction industry, particularly in the United States where the majority of gypsum consumed is used for building plasters, the manufacture of portland cement, and wallboard products flue gas desulfurization (FGD) units as feedstock continues, this could result in less mining of natural gypsum. The availability of inexpensive natural gas, however, may limit the additional construction of FGD units and, therefore, the use of synthetic gypsum in wallboard Gypsurm imports increased by 15% compared with those of 2015 Exports. although very iow compared with imports and often subject to wide fluctuations, decreased by 27%.
