About glass; glass frit and other glass, in the form of powder, granules or flakes

HS code 320740 covers a diverse range of glass products, including glass frit, powder, granules, and flakes. These materials play a crucial role in various industries, from construction and ceramics to electronics and specialty coatings. As a versatile and essential raw material, the glass products under this code contribute significantly to the global economy, supporting a wide array of manufacturing and industrial processes.

Production process

The production of glass frit, powder, granules, and flakes typically involves the melting and cooling of raw materials, such as silica, soda ash, and various mineral additives. The molten glass is then subjected to various mechanical processes, including grinding, crushing, and sieving, to achieve the desired particle size and shape. Specialized techniques, such as controlled cooling and chemical treatments, may also be employed to impart specific properties to the final products.

Production inputs

The main inputs required for the production of glass frit, powder, granules, and flakes include silica sand, soda ash, limestone, and various mineral additives. Depending on the specific application, other raw materials, such as metal oxides or specialized chemicals, may also be incorporated. Additionally, the industry relies on specialized equipment, such as glass furnaces, grinding mills, and sieving systems, to ensure efficient and consistent production.

Production outputs

The glass products covered by HS code 320740 are widely used as raw materials in a variety of industries. The glass frit, powder, granules, and flakes may be incorporated into the manufacture of 701000 Glass and glassware, 690100 Ceramic products, 854400 Insulated wire, cable and other electric conductors, and 321100 Prepared driers, pigments, paints, varnishes and related products, among others.
