About glass fibres; (including glass wool), chopped strands, of a length of not more than 50mm

HS code 701911 covers the production of glass fibers, including glass wool, with chopped strands of a length not exceeding 50mm. This industry plays a crucial role in the broader manufacturing and construction sectors, providing essential materials for a wide range of applications. Glass fibers are valued for their strength, durability, and insulating properties, making them indispensable in industries such as 700319 (Glass fibers (including glass wool) and articles thereof), 680610 Slag wool, rock wool and similar mineral wools, and 392010 Plates, sheets, film, foil and strip, of polymers of ethylene, non-cellular and not reinforced, laminated, supported or similarly combined with other materials.

Production process

The production of glass fibers with chopped strands of a length not exceeding 50mm typically involves a multi-step process. First, raw materials such as silica sand, limestone, and other minerals are melted in a high-temperature furnace to create molten glass. The molten glass is then extruded through small orifices, forming continuous glass filaments. These filaments are then chopped into short strands, often using specialized cutting equipment. The chopped strands are then processed further, which may include processes such as coating, drying, and packaging, depending on the specific end-use requirements.

Production inputs

The main inputs required for the production of HS code 701911 glass fibers include raw materials such as silica sand, limestone, and other mineral components. Additionally, the industry relies on specialized machinery and equipment for the melting, extrusion, and chopping processes. Energy sources, such as electricity or natural gas, are also essential for the high-temperature furnaces used in the production process.

Production outputs

The primary output of HS code 701911 is chopped glass fiber strands, which are used in a variety of applications. These glass fibers are often incorporated into other products, such as 701939 (Glass fibres (including glass wool) and articles thereof (excluding glass inners for vacuum flasks or for other vacuum vessels)), 701940 Woven fabrics of glass fibres, and 701990 (Glass fibres (including glass wool) and articles thereof (excluding glass inners for vacuum flasks or for other vacuum vessels, and woven fabrics of glass fibres)).
