Glass fibres; n.e.c. in heading no. 7019
HS v2022 Code: 701990
About glass fibres; n.e.c. in heading no. 7019
HS code 701990 covers a diverse range of glass fiber products that are not specifically classified elsewhere in the 7019 heading. These glass fibers have a wide array of applications across various industries, including construction, transportation, electronics, and consumer goods. As a versatile and high-performance material, glass fibers play a crucial role in the global economy, providing essential components and reinforcements for a multitude of products and systems.
Production process
The production of glass fibers classified under HS code 701990 typically involves the melting of raw materials, such as sand, limestone, and other mineral compounds, at high temperatures. The molten glass is then extruded through small orifices to form continuous filaments or chopped into shorter lengths. These glass fibers can be further processed into various forms, including mats, rovings, yarns, and fabrics, depending on the specific application requirements.
Production inputs
The main inputs required for the production of glass fibers under HS code 701990 include high-purity silica sand, limestone, alumina, and other mineral additives. Specialized manufacturing equipment, such as glass-melting furnaces, fiber-forming machines, and textile processing machinery, are also essential for the production process. Additionally, energy sources, such as natural gas or electricity, are required to maintain the high temperatures necessary for glass melting and fiber formation.
Production outputs
The glass fibers classified under HS code 701990 are used in a wide range of applications, including 701931 Mats, 701932 (Thin sheets (voiles), webs, mats, mattresses, boards and similar nonwoven products), 701939 Other, and 701940 Woven fabrics of glass fibres. These glass fiber products are often used as reinforcements in composite materials, insulation materials, filtration media, and various other industrial and consumer applications.
