Polyphosphates; other than sodium triphosphate (sodium tripolyphosphate), whether or not chemically defined

HS v2017 Code: 283539

About polyphosphates; other than sodium triphosphate (sodium tripolyphosphate), whether or not chemically defined

HS code 283539 covers a range of polyphosphate compounds, excluding sodium triphosphate (sodium tripolyphosphate). These polyphosphates are widely used in various industries, from detergents and water treatment to food additives and flame retardants. Their ability to sequester metal ions, control pH, and act as dispersing agents makes them essential ingredients in many commercial and industrial applications, contributing to the overall efficiency and effectiveness of diverse manufacturing processes.

Production process

Polyphosphates are typically produced through the reaction of phosphoric acid with various metal oxides or hydroxides. The specific production techniques can vary depending on the desired polyphosphate compound, but generally involve controlled heating, mixing, and purification steps to ensure the desired chemical composition and purity levels.

Production inputs

The main inputs required for the production of polyphosphates under HS code 283539 include phosphoric acid, various metal compounds (such as sodium, potassium, or ammonium compounds), and energy sources for the heating and processing steps. Specialized equipment, such as reactors, filtration systems, and drying units, are also essential for the efficient and consistent manufacture of these products.

Production outputs

The polyphosphates produced under HS code 283539 find applications in a wide range of industries. They are commonly used as detergent builders, water softeners, and dispersing agents in 340220 Washing preparations, including auxiliary washing preparations and 340290 (Organic surface-active agents (other than soap); surface-active preparations, washing preparations (including auxiliary washing preparations) and cleaning preparations, whether or not containing soap, n.e.c. in heading 3402). Additionally, these polyphosphates are utilized in 281920 Phosphoric acid and polyphosphoric acids and 281810 (Aluminium oxide (including artificial corundum)) production, as well as in various food, pharmaceutical, and industrial applications.
