HS v2022 Code: 700530

About glass; float glass and surface ground or polished glass, in sheets, wired glass, whether or not having an absorbent or reflecting layer

HS code 700530 covers a wide range of glass products that are essential for various industries, including construction, automotive, and electronics. This category encompasses float glass, which is a high-quality, flat glass produced through a specialized manufacturing process, as well as surface-ground or polished glass sheets and wired glass. These materials are widely used in applications that require transparency, durability, and specific optical properties, making them a crucial component of the global glass industry.

Production process

The production of the glass products covered under HS code 700530 typically involves a multi-step process. Float glass is manufactured by pouring molten glass onto a large, flat surface, where it spreads and forms a smooth, uniform sheet. This sheet is then carefully controlled and cooled to achieve the desired thickness and properties. Surface grinding and polishing techniques are then applied to create the desired finish, such as increased clarity or specific reflective qualities.

Production inputs

The main inputs required for the production of the glass products under HS code 700530 include high-quality raw materials such as silica sand, soda ash, and limestone. Specialized machinery, such as float glass production lines and grinding/polishing equipment, are also essential. Additionally, energy sources, such as natural gas or electricity, are needed to power the manufacturing process.

Production outputs

The glass products covered under HS code 700530 are primarily used in the construction, automotive, and electronics industries. The float glass, surface-ground glass, and wired glass produced under this code can be further processed and incorporated into a wide range of end-products, including 701910 Glass fibers and articles thereof, 700910 Glass mirrors, and 700800 Multiple-walled insulating units of glass.
