Glass; unworked, in rods

HS v2017 Code: 700220

About glass; unworked, in rods

HS code 700220 covers the classification of unworked glass in rod form. This industry plays a crucial role in the broader glass and glass products sector, which is an integral part of the global manufacturing and construction industries. The production of glass rods serves as a foundational input for a wide range of downstream applications, making it an important component of the overall economy.

Production process

The production of unworked glass rods typically involves the melting of raw materials, such as sand, soda ash, and limestone, in a high-temperature furnace. The molten glass is then extruded or drawn through a die to form the desired rod shape. The rods may undergo annealing or other finishing processes to ensure their structural integrity and quality before being packaged and distributed.

Production inputs

The main inputs required for the production of glass rods under HS code 700220 include high-purity silica sand, soda ash, limestone, and other mineral additives. Specialized furnaces, extrusion or drawing equipment, and annealing ovens are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce capable of operating the specialized machinery and maintaining quality control standards.

Production outputs

The primary output of the industry covered by HS code 700220 is unworked glass rods, which are then consumed by a variety of downstream industries. These rods may be used in the production of 701931 optical fiber, 701940 glass fibers, and other specialized glass products. The glass rods may also be further processed into 700231 cast, rolled, or drawn glass, 700232 non-wired sheets, or 700233 wired sheets for various applications.
