About glass; drawn glass and blown glass, in sheets, whether or not having an absorbent, reflecting or non-reflecting layer, but not otherwise worked

HS code 7004 covers a wide range of glass products, including drawn glass and blown glass in sheet form. This industry plays a crucial role in the construction, automotive, and electronics sectors, providing essential materials for windows, displays, and various other applications. The global glass industry is a significant contributor to the economy, with growing demand driven by urbanization, technological advancements, and the need for energy-efficient building materials.

Production process

The production of glass sheets under HS code 7004 primarily involves two main techniques: drawn glass and blown glass. Drawn glass is produced by drawing molten glass through a die, resulting in thin, uniform sheets. Blown glass, on the other hand, is created by blowing air into a molten glass bubble, which is then flattened into sheets. Both processes require precise temperature control, specialized equipment, and skilled labor to ensure the desired thickness, clarity, and quality of the final product.

Production inputs

The main inputs for the glass industry under HS code 7004 include raw materials such as silica sand, soda ash, and limestone, as well as various additives and colorants. Additionally, the industry relies on specialized machinery, including glass-melting furnaces, drawing or blowing equipment, and annealing ovens. Energy, in the form of electricity or natural gas, is another critical input for the high-temperature processes involved in glass production.

Production outputs

The primary outputs of the glass industry under HS code 7004 are sheet glass products, which can be used in a variety of applications. These include 7005 Float glass and surface ground or polished glass, in sheets, whether or not having an absorbent, reflecting or non-reflecting layer, but not otherwise worked, 7006 Glass of heading 7003, 7004 or 7005, bent, edge-worked, engraved, drilled, enamelled or otherwise worked, but not framed or fitted with other materials, and 7007 (Safety glass, consisting of toughened (tempered) or laminated glass). The glass sheets produced under HS code 7004 are often further processed and incorporated into other products, such as windows, mirrors, and display panels.
