Glass; cast glass and rolled glass, wired sheets, whether or not having an absorbent or reflecting layer but not otherwise worked

HS code 700320 covers a range of glass products, including cast glass and rolled glass wired sheets. These materials are widely used in construction, automotive, and various industrial applications due to their durability, versatility, and ability to provide insulation and safety features. The glass industry plays a crucial role in the global economy, supporting a diverse range of downstream sectors and contributing to sustainable development through the production of energy-efficient and recyclable materials.

The production of glass products under HS code 700320 typically involves a multi-step process. First, raw materials such as sand, soda ash, and limestone are melted at high temperatures to create the molten glass. The molten glass is then either cast into molds or rolled between metal rollers to create the desired sheet or wired glass. In the case of wired glass, a wire mesh is embedded within the glass during the rolling process to enhance its strength and safety properties. The glass sheets may also undergo additional processing, such as the application of absorbent or reflecting layers, to meet specific performance requirements.

The main inputs required for the production of glass products under HS code 700320 include raw materials such as sand, soda ash, and limestone, as well as specialized machinery and equipment for melting, casting, and rolling the glass. Energy sources, such as natural gas or electricity, are also essential for the high-temperature manufacturing process. Additionally, skilled labor and technical expertise are necessary to ensure the quality and consistency of the final products.

The glass products covered by HS code 700320 are primarily used in construction, automotive, and industrial applications. These materials can be further processed and incorporated into a wide range of end-products, including 700510 Float glass and surface ground or polished glass, 700600 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 701931 Mats. The versatility and durability of these glass products make them essential components in the production of energy-efficient buildings, safety-enhanced vehicles, and various industrial equipment.
