About glass fibres; chemically bonded fabrics, closed fabrics n.e.c. in heading 7019

HS code 701972 covers a diverse range of glass fiber products, including chemically bonded fabrics and closed fabrics not elsewhere classified in heading 7019. These materials play a crucial role in various industries, from construction and transportation to electronics and renewable energy. As a key component in composite materials, glass fibers offer exceptional strength, durability, and thermal insulation properties, making them indispensable in modern manufacturing processes.

Production process

The production of glass fibers and chemically bonded fabrics covered under HS code 701972 typically involves a multi-step process. First, molten glass is extruded through small orifices to form continuous filaments. These filaments are then coated with a chemical binder, which helps to strengthen and protect the fibers. The coated fibers are then woven or bonded together to create the desired fabric or mat structure. Depending on the specific application, the fabrics may undergo additional processing, such as heat treatment or lamination, to enhance their properties and performance.

Production inputs

The main inputs required for the production of goods under HS code 701972 include high-quality glass raw materials, such as silica sand, limestone, and other mineral additives. Specialized machinery, such as glass-melting furnaces, fiber-drawing equipment, and weaving or bonding machines, are also essential. Additionally, the chemical binders and coatings used to strengthen and protect the glass fibers are important inputs in this industry.

Production outputs

The primary outputs of the industry covered by HS code 701972 are various types of glass fiber fabrics and mats, which are then used as inputs in a wide range of downstream industries. These include the 701931 Glass fibres; woven fabrics of glass fibres, 701939 Glass fibres; woven fabrics of glass fibres, n.e.c. in heading 7019, and 701940 Glass fibres; fabrics of glass fibres, n.e.c. in heading 7019 industries, as well as the broader 7019 Glass fibres and articles thereof sector.
