About glass; drawn and blown, in sheets, (other than glass coloured throughout the mass (body tinted), opacified, flashed or having an absorbent, reflecting or non-reflecting layer)

HS code 700490 covers a wide range of flat glass products that are drawn or blown, but do not have any special coatings or tints. These types of glass sheets are commonly used in construction, automotive, and various industrial applications due to their versatility and cost-effectiveness. The global flat glass market is a crucial component of the broader 26 Building Materials industry, playing a vital role in the construction and manufacturing sectors worldwide.

Production process

The production of glass sheets under HS code 700490 typically involves two main techniques: drawing and blowing. In the drawing process, molten glass is drawn vertically through a die to create thin, uniform sheets. Alternatively, the blowing method involves inflating a glass bubble, which is then flattened to form the desired sheet. Both techniques require precise temperature control, careful annealing, and quality inspection to ensure the final products meet industry standards.

Production inputs

The primary raw materials required for the production of HS code 700490 glass sheets are silica sand, soda ash, and limestone. Manufacturers also rely on specialized machinery, such as glass-drawing or blowing equipment, as well as annealing ovens and cutting tools. Skilled labor, including glass technicians and engineers, is another crucial input for this industry.

Production outputs

The glass sheets produced under HS code 700490 are used in a wide range of applications, including 7007 Safety Glass, 7008 Insulating Glass Units, and 7009 Glass Mirrors. These glass products are often further processed or incorporated into other 94 Furniture and 85 Electrical Machinery and Equipment items, making them an essential component of many downstream industries.
