About glass; float glass and surface ground or polished glass, in sheets, non-wired, (other than coloured throughout the mass (body tinted), opacified, flashed or merely surface ground)

HS code 700529 covers a wide range of float glass and surface ground or polished glass products. These materials are essential components in various industries, including construction, automotive, and electronics. The global float glass market is expected to grow significantly in the coming years, driven by increasing demand for energy-efficient buildings and the rising popularity of smart glass technologies.

Production process

The production of float glass and surface ground or polished glass involves a multi-step process. First, the 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 and forms a smooth, uniform layer. This process is known as the float glass method. The glass is then slowly cooled and annealed to remove any internal stresses. Finally, the glass can be further processed, such as grinding, polishing, or coating, to meet specific requirements.

Production inputs

The main inputs required for the production of float glass and surface ground or polished glass include raw materials like sand, soda ash, and limestone, as well as specialized machinery and equipment for the melting, forming, and processing stages. Energy, in the form of electricity or natural gas, is also a significant input for the high-temperature furnaces used in the production process.

Production outputs

The primary outputs of HS code 700529 are various types of float glass and surface ground or polished glass sheets, which are used in a wide range of applications. These glass products are often consumed by industries such as 700600 Glass; glass of heading 7003, 7004 or 7005, bent, edge-worked, engraved, drilled, enamelled or otherwise worked, but not framed or fitted with other materials, 701910 (Glass fibres (including glass wool) and articles thereof (for example, yarn, woven fabrics)), and 701990 Glass; articles thereof, not elsewhere specified or included.
