Gypsum Suppliers, UAE

Gypsum (calcium sulphate dihydrate, CaSO4·2H2O) is a widely used industrial mineral essential to the GCC construction sector. It serves as a set retarder in Portland cement, as the primary raw material for plasterboard and plaster products, and as a soil conditioner in agriculture. Natural gypsum is quarried from surface deposits, while synthetic gypsum is a by-product of industrial desulphurization processes. Both forms are ground, calcined (to produce hemihydrate plaster of Paris), or processed into specialty products depending on the end use.

Saudi Arabia and the UAE are major gypsum producers and consumers, with extensive high-purity deposits in the Eastern Province, Yanbu corridor, and Oman border regions. The region's plasterboard industry has expanded rapidly to meet demand from residential, commercial, and hospitality construction. Procurement managers should specify gypsum by CaSO4·2H2O purity (typically above 85 percent for cement and above 90 percent for plasterboard), free moisture, combined water content, particle size, and levels of impurities such as clay, anhydrite, sodium chloride, and organic matter.

Sourcing considerations include proximity to the manufacturing plant (gypsum is a bulk, low-value-per-tonne commodity where freight cost is decisive), consistency of supply from the quarry, and the supplier's ability to deliver crushed, sized, or ground product to the required specification. Long-term supply contracts with established quarry operators are standard, and buyers should verify quarry reserve life to secure uninterrupted multi-year supply. Quality variation between quarry faces is common, so regular sampling and certificate-of-analysis verification are important quality assurance practices.
