Fibres; synthetic filament tow, of nylon or other polyamides, of aramids

HS v2022 Code: 550111

About fibres; synthetic filament tow, of nylon or other polyamides, of aramids

HS code 550111 covers the production of synthetic filament tow, a crucial raw material used in the manufacture of various textile products. This industry plays a vital role in the global textile supply chain, providing essential inputs for the production of fabrics, apparel, and other textile-based goods. The demand for synthetic filament tow is driven by its versatility, durability, and cost-effectiveness compared to natural fibers, making it a popular choice across a wide range of industries.

Production process

The production of synthetic filament tow under HS code 550111 typically involves the extrusion of molten nylon or other polyamide polymers through a spinneret, creating continuous filaments. These filaments are then drawn, cooled, and gathered into a tow, which is a bundle of parallel filaments. The tow may undergo further processing, such as crimping or cutting, to enhance its properties and suitability for various textile applications.

Production inputs

The key inputs required for the production of synthetic filament tow under HS code 550111 include nylon or other polyamide polymers, which serve as the raw materials. Additionally, specialized machinery, such as extruders, spinnerets, and drawing equipment, are essential for the manufacturing process. Energy sources, such as electricity or steam, are also necessary to power the production facilities.

Production outputs

The primary output of the industry covered by HS code 550111 is synthetic filament tow, which is a versatile raw material used in the production of a wide range of textile products. This tow may be further processed and consumed by industries producing 550320 Fibres; artificial filament tow, 540233 Filaments; of nylon or other polyamides, textured, and 540247 Filaments; of nylon or other polyamides, other than textured, among others.
