Machines; for manufacturing or hot working glass or glassware, for making optical fibres and preforms thereof

HS v2017 Code: 847521

About machines; for manufacturing or hot working glass or glassware, for making optical fibres and preforms thereof

hs code 847521 covers a critical industry within the broader manufacturing sector. These specialized machines are essential for the production of glass and optical fiber, which are fundamental materials in a wide range of industries, from construction and electronics to telecommunications and renewable energy. The machines described by this code play a vital role in shaping the global economy by enabling the manufacture of essential components and products.

Production process

The machines classified under hs code 847521 are used for a variety of glass and optical fiber production processes. This can include techniques such as glass blowing, pressing, and molding, as well as the drawing of optical fiber preforms into long, thin strands of optical fiber. These machines utilize advanced heating and forming technologies to precisely control the temperature, shape, and properties of the glass or optical fiber being produced.

Production inputs

The key inputs required for the machines covered by hs code 847521 include high-quality raw materials such as silica sand, soda ash, and other mineral components used in glass and optical fiber formulations. Additionally, these machines require specialized heating elements, precision control systems, and other advanced mechanical components to ensure consistent and reliable operation. The availability of skilled technicians to operate and maintain these machines is also a critical input for this industry.

Production outputs

The primary outputs of the machines classified under hs code 847521 are glass products, such as containers, tableware, and architectural glass, as well as optical fibers used in telecommunications, data transmission, and other applications. These outputs are then consumed by a wide range of other industries, including 851711 Telephone sets, 851762 Machines for the reception, conversion and transmission or regeneration of voice, images or other data, including switching and routing apparatus, and 701931 (Glass fibers (including glass wool) and articles thereof (for example, yarn, woven fabrics)), among others.
