China and India are the leading exporters of Ammonium sulfamate, accounting for the majority of global shipments, while the United States, Germany, and Brazil represent the largest importers. Ammonium sulfamate prices have remained relatively stable amid steady cross-border flows, with no major supply disruptions reported in recent years. Export volumes from China have increased modestly since 2022, while Indian exports have plateaued, and U.S. imports have grown consistently—reflecting sustained agricultural and industrial demand.
Ammonium sulfamate is a white, crystalline, odorless solid at room temperature, with moderate solubility in water and low volatility; it decomposes before melting, typically above 150 °C. It is an inorganic ammonium salt of sulfamic acid, classified as a nitrogen-containing fertilizer additive and chemical intermediate. Its primary industrial use is as a selective herbicide—particularly for controlling woody weeds and brambles—and as a flame retardant in cellulose-based materials such as paper and textiles. It also serves as a catalyst or curing agent in polymer and resin systems, and as a precursor in the synthesis of other sulfamate derivatives for agrochemical applications.
In the manufacture of fire-retardant compositions, for flameproofing textiles and paper products; in the manufacture of weed killing compositions; in electroplating solutions; for the generation of nitrous oxide gas.
