China and the United States are the leading exporters of potassium polymetaphosphate, accounting for a substantial majority of global shipments, while India, Germany, and South Korea represent the largest importers. Potassium polymetaphosphate prices have remained relatively stable amid steady cross-border flows. Export volumes from China have increased modestly over the past two years, while U.S. exports have held steady, and Indian imports have grown consistently—indicating strengthening demand in South Asian industrial applications.
Potassium polymetaphosphate is a white, crystalline, odorless solid that is highly hygroscopic and readily soluble in water; it has no defined melting point due to thermal decomposition upon heating. It is an inorganic polyphosphate salt, classified as a condensed phosphate compound. It serves primarily as a sequestrant, dispersant, and buffering agent in industrial formulations, and is widely used as a functional additive in detergents, water treatment chemicals, and food-grade preservatives. Typical application areas include household and institutional cleaning products, metal surface treatment solutions, textile processing aids, and as a stabilizer in dairy and beverage products.
