About glass fibres (including glass wool) and articles thereof (e.g. yarn, rovings, woven fabrics)

HS code 7019 covers a diverse range of glass fiber products, including glass wool, yarns, rovings, and woven fabrics. These materials play a crucial role in various industries, from construction and transportation to electronics and renewable energy. As a versatile and high-performance material, glass fiber products are in high demand globally, contributing significantly to international trade and the broader economy.

Production process

The production of glass fiber products typically involves a multi-step process. First, molten glass is extruded through small orifices to form continuous filaments. These filaments are then gathered and processed into various forms, such as yarns, rovings, or mats. Woven fabrics are created by weaving or knitting the glass fiber strands. The specific techniques used may vary depending on the desired end-product, but the core process of transforming molten glass into functional materials remains the foundation of this industry.

Production inputs

The primary inputs for the glass fiber industry include high-purity silica sand, limestone, and other mineral raw materials. Specialized machinery, such as glass melting furnaces, fiber-forming equipment, and weaving/knitting machines, are also essential for the production process. Additionally, the industry relies on a skilled workforce capable of operating the complex equipment and ensuring quality control throughout the manufacturing stages.

Production outputs

The glass fiber products covered under HS code 7019 are used in a wide range of applications. Glass yarns, rovings, and woven fabrics are commonly used in the manufacture 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 applications in the production of 7013 (Glassware of a kind used for table, kitchen, toilet, office, indoor decoration or similar purposes (other than that of heading 7010 or 7018)), 7014 (Signalling glassware and optical elements of glass (other than those of heading 7015), not optically worked), and 7016 Paving blocks, slabs, bricks, squares, tiles and other articles of pressed or moulded glass, whether or not wired, of a kind used for building or construction purposes; glass cubes and other glass smallwares, whether or not on a backing, for mosaics or similar decorative purposes; leaded lights and the like; multicellular or foam glass in blocks, panels, plates, shells or similar forms.
