Glass fibres; open woven fabrics of a width exceeding 30cm

HS v2022 Code: 701966

About glass fibres; open woven fabrics of a width exceeding 30cm

HS code 701966 covers a critical component of the textile and composite materials industries - glass fibres and open woven fabrics made from them. These materials have a wide range of applications, from insulation and reinforcement in construction to specialized textiles and advanced composites used in aerospace, automotive, and other high-performance sectors. As a key input for many downstream industries, the glass fibres and fabrics described by this code play an important role in the broader global economy.

Production process

Glass fibres are typically produced through a process called melt spinning. Molten glass is extruded through small holes in a bushing to form continuous filaments, which are then cooled and coated with a sizing agent to protect the delicate fibres. These individual fibres are then gathered together and can be woven into open fabrics on specialized looms, creating the materials covered by HS code 701966.

Production inputs

The primary inputs for the production of glass fibres and open woven fabrics under HS code 701966 are high-purity glass raw materials, such as silica sand, limestone, and other mineral compounds. Specialized manufacturing equipment, including fibre extrusion systems, winding machines, and weaving looms, are also essential for this industry. Additionally, the application of sizing agents and other chemical treatments is an important part of the production process.

Production outputs

The glass fibres and open woven fabrics described by HS code 701966 are used as inputs for a wide range of downstream industries. The fibres and fabrics may be further processed into reinforced composites, insulation materials, specialty textiles, and other products covered by codes such as 392010 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 680610 Slag wool, rock wool and similar mineral wools; exfoliated vermiculite, expanded clays, foamed slag and similar expanded mineral materials, and 630190 Blankets and travelling rugs, among others.
