Glass fibres; (including glass wool), yarns and slivers
HS v2022 Code: 701913
About glass fibres; (including glass wool), yarns and slivers
HS code 701913 covers a diverse range of glass fiber products, including glass wool, yarns, and slivers. These materials play a crucial role in various industries, from construction and insulation to textiles and composites. Glass fibers offer exceptional strength, durability, and thermal properties, making them indispensable in a wide array of applications that drive economic growth and technological advancement.
Production process
The production of glass fibers typically involves a multi-step process. First, raw materials such as silica sand, limestone, and other minerals are melted at high temperatures to form molten glass. This molten glass is then extruded through small orifices, creating fine, continuous filaments. These filaments are then processed into various forms, such as yarns, slivers, or mats, depending on the intended application. The specific techniques used, such as drawing, twisting, or weaving, can vary depending on the desired product characteristics.
Production inputs
The primary inputs for the production of glass fibers include silica sand, limestone, and other mineral raw materials. Specialized machinery, such as glass-melting furnaces, fiber-drawing equipment, and textile processing machines, are also essential for the manufacturing process. Additionally, energy sources, such as electricity or natural gas, are required to power the high-temperature melting and fiber-forming operations.
Production outputs
The glass fibers produced under HS code 701913 have a wide range of applications. They are commonly used in the manufacture of 701912 (Glass fibres (including glass wool) and articles thereof (for example, yarn, woven fabrics)), 701919 (Glass fibres (including glass wool) and articles thereof (for example, yarn, woven fabrics), other than non-woven and articles of such materials), and 701990 (Glass fibres (including glass wool) and articles thereof (for example, yarn, woven fabrics), other). These glass fiber products are essential inputs for industries such as construction, transportation, electronics, and renewable energy, among others.
