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 are essential inputs for various industries, from construction and ceramics to electronics and specialty coatings. The global glass industry is a significant contributor to the economy, with a market size estimated at over $200 billion and projected to grow steadily in the coming years.

Production process

The production of glass frit, powder, granules, and flakes typically involves a multi-step process. First, raw materials such as silica sand, soda ash, and limestone are melted at high temperatures, often exceeding 1,500°C. The molten glass is then rapidly cooled, causing it to fracture into small, irregular pieces known as frit. The frit is then further processed, either by grinding into a fine powder or by sieving to produce granules and flakes of various sizes.

Production inputs

The main inputs required for the production of glass frit, powder, granules, and flakes include silica sand, soda ash, limestone, and other mineral additives. Specialized equipment, such as glass furnaces, grinding mills, and sieving machines, are also essential for the manufacturing process. Additionally, energy sources, such as natural gas or electricity, are needed to power the high-temperature melting and cooling stages.

Production outputs

The glass frit, powder, granules, and flakes produced under HS code 320740 are used as inputs for a wide range of industries. They are commonly used in the production of 320710 Glass in the mass, glass powder, granules or flakes for decorative and functional purposes, as well as in the manufacture of 701900 Glass fibers and articles thereof, 701910 (Glass fibers (including glass wool) and articles thereof), and 701990 (Glass fibers (including glass wool) and articles thereof, n.e.c. in heading no. 7019).
