Glass; unworked, in rods

HS v2022 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 economy. Glass rods are versatile raw materials used in a wide range of applications, from optical fibers and laboratory equipment to decorative arts and specialty industrial components.

Production process

The production of unworked glass rods typically involves the melting of raw materials, such as silica sand, soda ash, and other mineral additives, in a high-temperature furnace. The molten glass is then drawn or extruded into long, continuous rods of varying diameters and lengths, depending on the intended application. The rods may undergo additional processing, such as annealing or surface treatment, to enhance their properties and durability.

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 glass-melting furnaces, drawing or extrusion equipment, and annealing ovens are also essential for the manufacturing process. Additionally, skilled labor and advanced quality control measures are necessary to ensure the consistent production of high-quality glass rods.

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 include the 853120 optical fiber communications, 701990 glass and glassware, and 902780 other optical instruments and appliances sectors, among others. The versatility of glass rods allows them to be further processed and incorporated into a wide range of products, contributing to the overall growth and development of the global economy.
