HS v2022 Code: 700510

About glass; float glass and surface ground or polished glass, in sheets, non-wired, having an absorbent reflecting or non-reflecting layer

HS code 700510 covers a critical component of the global glass industry - float glass and surface ground or polished glass in sheet form. This type of glass is widely used in a variety of applications, including construction, automotive, and furniture manufacturing, making it an essential material for many industries. The production and trade of this glass product plays a significant role in the broader economy, supporting a range of downstream activities and contributing to the development of infrastructure, transportation, and consumer goods.

Production process

The production of float glass and surface ground or polished glass sheets involves a multi-step process. First, raw materials such as sand, soda ash, and limestone are melted in a furnace to create a molten glass. This molten glass is then poured onto a large, flat surface, where it spreads out and forms a smooth, uniform sheet. The sheet is then slowly cooled and annealed to remove any internal stresses. Finally, the glass may undergo additional processing, such as grinding, polishing, or the application of specialized coatings, to meet specific performance requirements.

Production inputs

The main inputs required for the production of HS code 700510 glass products include raw materials such as 2505 Silica Sands, 2511 Calcium Carbonate, and 2813 Soda Ash. Additionally, specialized machinery and equipment, such as glass furnaces, float baths, and polishing lines, are essential for the manufacturing process. Energy sources, such as natural gas or electricity, are also crucial inputs for the melting and processing of the glass.

Production outputs

The primary output of HS code 700510 is float glass and surface ground or polished glass sheets, which are then used in a wide range of applications. These glass products are often consumed by industries such as 7007 Safety Glass, 7008 Multiple-Walled Insulating Units of Glass, and 7009 Glass Mirrors, among others. The versatility of these glass sheets makes them an important material for the construction, automotive, and furniture sectors, contributing to the development of various end-use products.
