HS v2017 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. Its unique properties, such as its ability to be coated with absorbent, reflecting, or non-reflecting layers, make it a versatile and in-demand product worldwide.

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 at high temperatures. The molten glass is then poured onto a large, flat surface, where it spreads out and forms a smooth, uniform sheet. This 'float' process gives the glass its characteristic flat and even surface. The glass sheet is then slowly cooled and annealed to remove internal stresses. Finally, the glass may undergo additional processing, such as grinding, polishing, or the application of specialized coatings, to meet specific customer requirements.

Production inputs

The main inputs required for the production of HS code 700510 glass products include high-purity raw materials such as 2505 Silica sand, 2511 Barium sulfate, 2518 Dolomite, and 2807 Sulfuric acid. Additionally, specialized machinery, such as float glass production lines and grinding/polishing equipment, are essential for the manufacturing process. Energy, in the form of electricity or natural gas, is also a significant input for the high-temperature melting and annealing stages.

Production outputs

The primary output of HS code 700510 is float glass and surface ground or polished glass sheets, which are then used as inputs for a wide range of industries. These glass sheets may be further processed, coated, or incorporated into final products such as 7007 Safety glass, 7008 Multiple-walled insulating units of glass, and 7009 Glass mirrors. The versatility of this type of glass makes it a crucial component in the construction, automotive, and furniture sectors, among others.
