HS v2017 Code: 700530

About glass; float glass and surface ground or polished glass, in sheets, wired glass, whether or not having an absorbent or reflecting layer

HS code 700530 covers a range of glass products that are widely used in construction, automotive, and various other industries. This category includes float glass, surface ground or polished glass, and wired glass, which can be further processed to have absorbent or reflecting layers. These glass products play a crucial role in the global economy, providing essential materials for a diverse array of applications, from energy-efficient buildings to advanced transportation solutions.

Production process

The production of the glass products covered under HS code 700530 typically involves a multi-step process. The primary technique is the float glass process, where molten glass is poured onto a large, flat surface and allowed to spread and form a smooth, uniform sheet. This sheet is then cooled and can undergo further processing, such as grinding, polishing, or the application of specialized coatings. Wired glass is produced by embedding wire mesh into the glass during the manufacturing process, which enhances its strength and safety properties.

Production inputs

The main inputs required for the production of the glass products under HS code 700530 include high-quality raw materials such as silica sand, soda ash, and limestone. Specialized machinery, such as float glass production lines and grinding/polishing equipment, are also essential. Additionally, energy sources, such as natural gas or electricity, are needed to power the manufacturing process, which involves high-temperature melting and shaping of the glass.

Production outputs

The glass products covered under HS code 700530 are primarily used in the construction industry, where they are incorporated into windows, facades, and other architectural elements. They are also widely used in the automotive industry for windshields, side windows, and other vehicle glazing. Additionally, these glass products may be consumed by 700510 Glass; float glass and surface ground or polished glass, in sheets, but not otherwise worked, 700520 Glass; wired glass, in sheets, and 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.
