Silicates; commercial alkali metal silicates, other than of sodium

HS code 283990 covers a diverse range of silicate compounds, excluding those of sodium. These silicates have a wide array of industrial applications, serving as essential raw materials in the production of glass, ceramics, detergents, and various other chemical products. They play a crucial role in the manufacturing and construction sectors, contributing to the development of the broader economy.

The production of commercial alkali metal silicates, other than sodium, typically involves the reaction of silicon dioxide (SiO2) with various alkali metal compounds, such as potassium hydroxide or lithium hydroxide. This process is carried out at high temperatures, often in specialized furnaces or reactors, to facilitate the formation of the desired silicate compounds. The resulting products are then further processed, purified, and formulated to meet the specific requirements of various industries.

The primary inputs for the production of HS code 283990 silicates include silicon dioxide (SiO2), which serves as the main raw material, as well as various alkali metal compounds, such as potassium hydroxide or lithium hydroxide. Additionally, the industry may require specialized equipment, such as furnaces, reactors, and purification systems, to ensure the efficient and consistent production of these silicate compounds.

The silicates produced under HS code 283990 find applications in a wide range of industries. They are used as raw materials in the manufacture of glass, ceramics, and other construction materials. Additionally, these silicates are employed as detergents, water softeners, and in the production of various chemical products. The outputs of this industry may be consumed by industries classified under codes such as 681100 Articles of asbestos-cement, of cellulose fiber-cement or the like, 701000 Glass and glassware, and 340220 Washing preparations, including auxiliary washing preparations and cleaning preparations, whether or not containing soap, other than those of heading 34.01.
