Glass; cast glass and rolled glass, profiles, not otherwise worked

HS code 700330 covers a range of glass products, including cast glass and rolled glass, that are not further processed beyond the initial shaping and forming stages. These glass products are widely used in construction, automotive, and various industrial applications, playing a crucial role in the broader economy. The versatility and durability of these glass profiles make them an essential material for a wide array of products and structures.

The production of glass products under HS code 700330 typically involves two main techniques: casting and rolling. In the casting process, molten glass is poured into molds and allowed to solidify, creating a desired shape or profile. The rolling process involves passing the molten glass through rollers, which flatten and shape the material into the required profiles. These techniques allow for the efficient and precise manufacturing of a variety of glass products, from simple flat panels to more complex shapes and profiles.

The primary inputs for the production of glass products under HS code 700330 are raw materials such as silica sand, soda ash, and limestone. These materials are combined and melted at high temperatures to create the molten glass. Additionally, specialized machinery, including casting molds and rolling equipment, is essential for the shaping and forming of the glass profiles. Energy sources, such as natural gas or electricity, are also required to maintain the high temperatures necessary for the manufacturing process.

The glass products covered by HS code 700330 are used in a wide range of applications, including 700510 Glass; float glass and surface ground or polished glass, in sheets, but not otherwise worked, 700521 Glass; float glass and surface ground or polished glass, in sheets, but not otherwise worked, of a thickness not exceeding 3.5 mm, and 700529 Glass; float glass and surface ground or polished glass, in sheets, but not otherwise worked, of a thickness exceeding 3.5 mm. These glass profiles are often further processed and incorporated into various products, such as windows, doors, and architectural elements.
