HS v2017 Code: 7019
About glass fibres (including glass wool) and articles thereof (e.g. yarn, woven fabrics)
HS code 7019 covers a diverse range of glass fiber products, including glass wool, yarns, and woven fabrics. These materials play a crucial role in various industries, from construction and insulation to electronics and transportation. As a versatile and durable material, glass fiber is highly valued for its strength, thermal and electrical insulation properties, and chemical resistance. The global glass fiber market is expected to continue growing, driven by increasing demand from end-use sectors and the ongoing shift towards more sustainable and energy-efficient solutions.
Production process
The production of glass fiber products 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, forming continuous glass filaments. These filaments are then drawn, coated, and either chopped into short fibers (glass wool) or woven into fabrics and yarns. The specific techniques used can vary depending on the desired end-product, with factors such as fiber diameter, length, and surface treatment playing a crucial role in the final properties of the glass fiber.
Production inputs
The main inputs required for the production of glass fiber products include raw materials such as silica sand, limestone, and other mineral additives. Specialized machinery, including glass melting furnaces, fiber-forming equipment, and weaving or knitting machines, are also essential. Additionally, various chemical treatments and coatings may be applied to the glass fibers to enhance their properties, such as adhesion, moisture resistance, or thermal stability.
Production outputs
The glass fiber products covered under HS code 7019 have a wide range of applications. Glass wool is commonly used for thermal and acoustic insulation in buildings, while glass fiber yarns and fabrics are used in the production of 5407 Woven fabrics of synthetic filament yarn, 5408 Woven fabrics of artificial filament yarn, and 7010 Carboys, bottles, flasks, jars, pots, phials, ampoules and other containers, of glass, of a kind used for the conveyance or packing of goods; preserving jars of glass; stoppers, lids and other closures, of glass. These materials also find use in the manufacturing of 8708 Parts and accessories of motor vehicles, 8544 Insulated wire, cable and other insulated electric conductors; optical fibre cables; all having individual sheaths, whether or not assembled with conductors or fitted with connectors, and 8545 Carbon electrodes, carbon brushes, lamp carbons, battery carbons and other articles of graphite or other carbon, with or without metal, of a kind used for electrical purposes.
