About glass fibres; n.e.c. in heading no. 7019

HS code 701990 covers a wide range of glass fiber products that are not specifically classified elsewhere in the 7019 heading. These glass fibers have a diverse range of applications, from insulation and reinforcement in construction materials to specialized uses in electronics and aerospace engineering. As a versatile and essential component in many industries, the glass fiber sector plays a crucial role in the global economy.

Production process

The production of glass fibers under HS code 701990 typically involves the melting of raw materials, such as sand, limestone, and other minerals, at high temperatures. The molten glass is then extruded through small orifices to form continuous filaments or chopped into shorter fibers. These fibers can be further processed into various forms, including mats, rovings, and yarns, depending on the intended application.

Production inputs

The main inputs required for the production of glass fibers under HS code 701990 include silica sand, limestone, alumina, and other mineral additives. Specialized equipment, such as glass-melting furnaces, fiber-forming machines, and winding or chopping systems, are also essential for the manufacturing process. Additionally, energy sources, such as natural gas or electricity, are needed to maintain the high temperatures required for glass melting and fiber formation.

Production outputs

The glass fibers produced under HS code 701990 have a wide range of applications, including 701931 Mats, 701932 Thin sheets (voiles, 701939 Other, and 701940 Woven fabrics of glass fibres. These glass fiber products are often used as reinforcement in 392010 Plates, sheets, film, foil and strip, of plastics, 681181 Corrugated sheets, and 870810 Bumpers and parts thereof within the broader manufacturing and construction industries.
