About glass fibres; (including glass wool), rovings
HS code 701912 covers the classification of glass fibres, including glass wool and rovings. This industry plays a crucial role in the broader manufacturing and construction sectors, providing essential materials for a wide range of applications. Glass fibres are valued for their strength, durability, and insulating properties, making them a versatile and in-demand product across various industries.
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, forming thin, continuous filaments. These filaments are then gathered and wound onto spools, creating the glass fibre rovings. Alternatively, the molten glass can be blown or spun into a wool-like material, known as glass wool. Both processes result in the glass fibres that are classified under HS code 701912.
Production inputs
The main inputs required for the production of glass fibres under HS code 701912 include raw materials such as 2505 Silica sand, 2521 Limestone flux, and other mineral additives. Specialized machinery, such as glass melting furnaces, fibre-forming equipment, and winding machines, are also essential for the manufacturing process. Additionally, energy sources, such as electricity or natural gas, are required to power the high-temperature operations involved in glass fibre production.
Production outputs
The primary outputs of the glass fibre industry classified under HS code 701912 are the glass fibres themselves, which can be used in a variety of applications. These glass fibres may be further processed or incorporated into other products, such as 7019 Glass fibres and articles thereof, 7013 Glassware for table, kitchen, toilet, office, indoor decoration or similar purposes, and 6810 Articles of cement, of concrete or of artificial stone, whether or not reinforced. The versatility of glass fibres makes them an essential material for industries ranging from construction and transportation to electronics and renewable energy.
