About HS Code 283911
Sodium metasilicates are a class of inorganic compounds characterized by their high alkalinity and excellent cleaning properties, making them indispensable in various industrial and household applications. They are typically traded in anhydrous, pentahydrate, or nonahydrate forms, each offering specific benefits in terms of solubility and alkalinity. Their primary use is as a builder in detergents and cleaning agents, where they enhance cleaning efficiency, emulsify oils, and provide corrosion inhibition. Beyond cleaning, sodium metasilicates are utilized in textile processing, paper de-inking, metal cleaning, and as a binder in refractory materials. The international trade involves chemical manufacturers, detergent producers, and industrial cleaning suppliers. Major importers are often countries with robust manufacturing sectors that require effective cleaning solutions or have significant detergent production. Exporters are typically nations with access to raw materials like silica and soda ash, coupled with advanced chemical processing capabilities. Understanding the specific hydrate form is crucial for accurate classification and application.
