About HS Code 283919

This HS code encompasses a broad category of sodium silicates, excluding the specific sodium metasilicates covered by 283911. This group includes various forms of sodium silicate, often referred to as "water glass," which are characterized by different SiO2:Na2O ratios. These compounds are typically traded as viscous liquids or solid powders/lumps. Their diverse applications stem from their adhesive, binding, and deflocculating properties. They are widely used in the production of detergents, adhesives, binders for foundry molds, coatings, and as flocculants in water treatment. Additionally, they serve as raw materials for silica gels and precipitated silica. The international trade involves chemical producers, manufacturers of construction materials, paper and pulp industries, and water treatment companies. Importers are often countries with significant industrial manufacturing, while exporters are typically nations with strong chemical production capabilities and access to raw materials. The specific ratio of silica to sodium oxide is a critical factor influencing their properties and end-use, and thus their trade.

Products Under This Code

Sodium silicate solution (water glass), Sodium orthosilicate, Sodium disilicate, Sodium polysilicate, Powdered sodium silicate, Anhydrous sodium silicate, Sodium silicate for detergents, Sodium silicate for adhesives

Real World Examples

PQ Corporation Sodium Silicate, W. R. Grace Sodium Silicate, BASF Sodium Silicate

Common Misclassification

This code is often confused with sodium metasilicates (283911) if the specific silicate ratio or "meta" designation is not clearly stated. It's also important to differentiate it from other alkali metal silicates (283990) if the cation is not sodium.

Products Classified Under 2839.19

Industry

This code belongs to the Chemicals industry.

Trade Overview

China, the USA, and Germany are leading countries in the import and export of various sodium silicates, reflecting their extensive industrial applications.
