About glass fibres; (including glass wool), rovings

HS code 701912 covers glass fibres, including glass wool and rovings. This industry plays a crucial role in the broader manufacturing and construction sectors, providing essential materials for a wide range of applications. Glass fibres are valued for their strength, durability, and insulating properties, making them a versatile and in-demand product across various industries.

Production process

The production of glass fibres typically involves melting raw materials, such as sand, limestone, and other minerals, at high temperatures. The molten glass is then extruded through small holes to form continuous filaments, which are then gathered into strands or rovings. These glass fibres can be further processed into a range of products, including insulation, reinforcement for composites, and textiles.

Production inputs

The main inputs required for the production of glass fibres under HS code 701912 include raw materials like silica sand, limestone, and other mineral additives. Specialized machinery, such as glass-melting furnaces, fibre-drawing equipment, and winding machines, are also essential for the manufacturing process. Additionally, energy sources, such as electricity or natural gas, are needed to power the high-temperature operations.

Production outputs

The primary outputs of the glass fibre industry covered by HS code 701912 are the glass fibres themselves, which can be used in a variety of applications. These glass fibres may be consumed by industries such as 701931 (Glass fibres; (including glass wool) mats), nc_link(701939)(Glass fibres; (including glass wool) other), nc_link(392010)(Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials), and nc_link(681181)(Corrugated sheets, of cellulose fibre-cement or the like), among others, where they serve as reinforcement, insulation, or other functional components.
