About HS Code 283539
This HS code covers a diverse range of polyphosphates, excluding the highly specific sodium tripolyphosphate (STPP) found in 2835.31. These "other" polyphosphates include compounds like sodium hexametaphosphate, potassium polyphosphates, and ammonium polyphosphates, each with unique industrial applications. They are widely used as sequestrants, dispersants, emulsifiers, and flame retardants in various sectors, including food processing, water treatment, ceramics, and textiles. Countries with advanced manufacturing capabilities and a need for specialized chemical additives are key importers. Exporters are typically chemical manufacturing hubs with the expertise to produce these complex inorganic polymers. Understanding the specific chain length and cation of the polyphosphate is crucial for correct classification and application, as their properties vary significantly. The trade in these specialized chemicals underpins many modern industrial processes, from enhancing food texture to preventing fires.
Products Under This Code
Sodium hexametaphosphate (SHMP), Potassium tripolyphosphate (KTPP), Ammonium polyphosphate (APP), Tetrasodium pyrophosphate (TSPP), Sodium acid pyrophosphate (SAPP), Sodium polyphosphate glass
Real World Examples
ICL (food phosphates), Innophos (specialty phosphates), Budenheim (food ingredients), Clariant (flame retardants)
Common Misclassification
This code is often confused with 283531 if the polyphosphate is sodium tripolyphosphate, or with 283529 if it's a complex orthophosphate rather than a true polyphosphate.
Products Classified Under 2835.39
Industry
This code belongs to the Chemicals industry.
Trade Overview
Major importers include industrialized nations like the USA, Germany, and Japan, while China, the USA, and European countries are significant exporters.
