Glass fibres; woven fabrics of rovings

HS v2017 Code: 701940

About glass fibres; woven fabrics of rovings

HS code 701940 covers the production and trade of glass fibers and woven fabrics made from glass rovings. Glass fibers are a versatile and widely used material, finding applications in a diverse range of industries, including construction, transportation, and electronics. As a lightweight, strong, and durable material, glass fibers play a crucial role in the global economy, contributing to the development of innovative products and technologies.

Production process

The production of glass fibers and woven fabrics of rovings typically involves a multi-step process. First, raw materials such as silica sand, limestone, and other minerals are melted at high temperatures to form molten glass. The molten glass is then extruded through small orifices, forming continuous glass filaments. These filaments are then gathered into strands, known as rovings, which can be woven or otherwise processed into a variety of fabric products.

Production inputs

The main inputs required for the production of glass fibers and woven fabrics of rovings include silica sand, limestone, and other mineral raw materials. Additionally, specialized machinery, such as glass melting furnaces, fiber-forming equipment, and weaving machines, are essential for the manufacturing process. Energy sources, such as electricity or natural gas, are also crucial inputs for the high-temperature operations involved in glass fiber production.

Production outputs

The primary outputs of HS code 701940 are glass fibers and woven fabrics made from glass rovings. These materials are widely used in a variety of applications, including 701931 Mats, 701932 (Thin sheets (voiles), webs, mats, mattresses, boards and similar nonwoven products), and 701939 Other. Glass fibers and woven fabrics are often consumed by industries such as construction, transportation, and electronics, where their unique properties make them valuable components in the production of various products.
