HS v2017 Code: 701919

About glass fibres; (including glass wool), slivers, yarns and threads

HS code 701919 covers a diverse range of glass fibre products, including glass wool, slivers, yarns, and threads. These materials play a crucial role in various industries, from construction and insulation to textiles and composites. As a key component in many high-performance applications, the glass fibre industry is an integral part of the broader manufacturing and industrial landscape.

Production process

The production of glass fibres typically involves a multi-step process. First, raw materials such as sand, limestone, and other minerals are melted at high temperatures to form molten glass. This molten glass is then extruded through small orifices, creating fine, continuous filaments. These filaments can be further processed into a variety of forms, including slivers, yarns, and threads, depending on the intended application.

Production inputs

The main inputs required for the production of glass fibres include raw materials such as 2505 Silica sand, 2521 Limestone and other mineral additives. Specialized machinery, such as glass melting furnaces and fibre-drawing equipment, are also essential for the manufacturing process. Additionally, energy sources, such as electricity or natural gas, are needed to maintain the high temperatures required for glass melting and fibre formation.

Production outputs

The glass fibres produced under HS code 701919 have a wide range of applications. They are commonly used in the construction industry for insulation, reinforcement, and composite materials. Additionally, these glass fibre products are utilized in the textile industry for the production of 5501 Synthetic filament tow, 5503 Synthetic staple fibres, and other specialty fabrics. The outputs of this industry can also be consumed by manufacturers of 8548 Electrical parts of machinery or apparatus, 8708 Parts and accessories of motor vehicles, and various other industries that require high-performance, lightweight, and durable materials.
