Glass fibres; chemically bonded fabrics

HS v2022 Code: 701971

About glass fibres; chemically bonded fabrics

HS code 701971 covers the production of glass fibre fabrics that are chemically bonded. These fabrics are an essential component in a wide range of industries, including construction, transportation, and electronics. They offer superior strength, durability, and thermal insulation properties, making them a versatile material for various applications. The global glass fibre market is expected to grow significantly in the coming years, driven by the increasing demand for lightweight and energy-efficient materials across multiple sectors.

Production process

The production of glass fibre fabrics under HS code 701971 typically involves a multi-step process. First, glass fibres are produced by melting and extruding molten glass through small orifices. These individual fibres are then woven or bonded together using chemical agents to create a cohesive fabric. The chemical bonding process helps to improve the fabric's strength, dimensional stability, and resistance to environmental factors such as heat, moisture, and chemicals.

Production inputs

The main inputs required for the production of glass fibre fabrics under HS code 701971 include raw glass materials, such as silica sand, limestone, and other mineral additives. Specialized machinery, such as glass fibre extrusion equipment and weaving or bonding machines, are also essential. Additionally, chemical binders and sizing agents are used to enhance the fabric's properties and performance.

Production outputs

The primary output of HS code 701971 is chemically bonded glass fibre fabrics, which find applications in a wide range of industries. These fabrics may be further processed or incorporated into 701939 Glass fibres; woven fabrics of glass fibres, 701940 Glass fibres; fabrics of glass fibres, not woven, or other related HS codes depending on the specific end-use requirements.
