Glass; drawn and blown, in sheets, coloured throughout the mass (body tinted), opacified, flashed or having an absorbent, reflecting or non-reflecting layer, but not otherwise worked

HS code 700420 covers a specific type of glass that is drawn and blown into sheets, with a distinct coloration throughout the material. This glass is often used in a variety of applications, including construction, automotive, and specialty industries, due to its unique optical and aesthetic properties. As a key component in the global glass manufacturing industry, this product plays an important role in the broader economy.

The production of glass covered under HS code 700420 typically involves a multi-step process. First, the raw materials, such as silica, soda ash, and other additives, are carefully measured and melted in a high-temperature furnace. The molten glass is then drawn or blown into thin sheets, which are subsequently cooled and annealed to ensure stability and durability. During this process, the glass can be tinted, opacified, or coated with various layers to achieve the desired optical properties.

The main inputs required for the production of HS code 700420 glass include high-purity silica sand, soda ash, limestone, and other mineral additives. Specialized equipment, such as glass-melting furnaces, drawing or blowing machines, and annealing ovens, are also essential for the manufacturing process. Additionally, skilled labor, including glass technicians and engineers, is necessary to ensure the consistent quality and performance of the final product.

The primary output of HS code 700420 is sheets of colored, opacified, or coated glass that can be used in a variety of applications. This glass may be further processed or incorporated into other products, such as 700510 Glass; float glass and surface ground or polished glass, in sheets, but not otherwise worked, 700600 Glass; of 70.03, 70.04 or 70.05, bent, edge-worked, engraved, drilled, enamelled or otherwise worked, but not framed or fitted with other materials, or 701931 (Glass fibres (including glass wool) and articles thereof (for example, yarn, woven fabrics)), depending on the specific requirements of the end-user.
