Glass fibres; non-woven products, mats

HS v2017 Code: 701931

About glass fibres; non-woven products, mats

HS code 701931 covers a diverse range of non-woven glass fiber products, including mats, webs, and other materials. These materials play a crucial role in various industries, from construction and transportation to electronics and renewable energy. As a key component in the production of fiberglass, this industry is integral to the broader manufacturing and engineering sectors, contributing to the development of innovative and high-performance products.

Production process

The production of glass fiber non-woven products typically involves a multi-step process. First, molten glass is extruded through small orifices, forming fine glass filaments. These filaments are then collected and bonded together using various techniques, such as mechanical entanglement, chemical binders, or thermal bonding. The resulting non-woven material can be further processed into mats, webs, or other specialized products, depending on the intended application.

Production inputs

The main inputs required for the production of glass fiber non-woven products include high-quality glass raw materials, such as silica sand, limestone, and other mineral additives. Specialized machinery, including glass melting furnaces, fiber-forming equipment, and bonding systems, are also essential. Additionally, the industry relies on a skilled workforce capable of operating and maintaining the complex production processes.

Production outputs

The primary outputs of HS code 701931 are a diverse range of non-woven glass fiber products, including mats, webs, and other materials. These outputs are widely used in various industries, such as 701939 Glass fibres; other, 701940 Glass fibres; woven fabrics of glass fibres, and 681181 Building materials of cement, concrete or artificial stone; containing fibres other than asbestos, where they serve as reinforcement, insulation, or structural components in a wide range of applications.
