2839.11.00.00 - Sodium metasilicates

This HTS category, 2839.11.00.00, specifically covers sodium metasilicates. These are inorganic chemical compounds consisting of sodium and silicate, often found in hydrated forms. Sodium metasilicates are typically crystalline solids and are primarily used in industrial applications, including as cleaning agents, detergents, adhesives, and as a component in cement and refractories. Their primary characteristic is their ability to form alkaline solutions when dissolved in water, contributing to their effectiveness in various industrial processes.

This classification distinguishes itself from its sibling category, 2839.19.00.00, which encompasses "Other" commercial alkali metal silicates of sodium. While both fall under the broader umbrella of sodium silicates, this specific subheading is for metasilicates, a distinct chemical structure with specific properties. The "Other" category would include sodium silicates that are not metasilicates, such as ortho-silicates or poly-silicates, depending on their chemical composition and structure.

As this is a leaf node, there are no further subcategories to introduce. Classification within 2839.11.00.00 is determined by the specific chemical identity of the sodium silicate as a metasilicate. Importers and exporters should ensure that the product's technical specifications and chemical analysis confirm it as a sodium metasilicate to ensure accurate classification and compliance with customs regulations.
