About HS Code 283990

This HS code covers commercial alkali metal silicates, excluding those of sodium, which are classified elsewhere. These compounds, such as potassium silicate or lithium silicate, are versatile inorganic chemicals used in a range of industrial applications. They serve as binders in welding rods, deflocculants in ceramics, components in detergents, and protective coatings. International trade involves countries with chemical manufacturing capabilities supplying these specialized silicates to industries globally. Key aspects to consider include the specific alkali metal (potassium, lithium), the silicate ratio, and the form (liquid solution, powder), as these dictate their suitability for different applications. Their demand is often tied to the health of the construction, manufacturing, and specialty chemical sectors.

Products Under This Code

Potassium silicate solution, Lithium silicate solution, Potassium silicate powder, Lithium silicate powder, Potassium waterglass, Lithium waterglass

Real World Examples

PQ Corporation Kasil, W. R. Grace & Co. Lithium Silicate, Evonik Potassium Silicate, Huber Engineered Materials Potassium Silicate

Common Misclassification

This code is distinct from sodium silicates (2839.11 or 2839.19) due to the specific alkali metal. It also differs from other silicon compounds like silicon dioxide (2811.22) or other silicates of non-alkali metals.

Products Classified Under 2839.90
