HS v2022 Code: 550119

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

HS code 550119 covers the trade and production of synthetic filament tow made from nylon or other polyamides, excluding aramids. This industry plays a crucial role in the global textile and manufacturing sectors, providing essential raw materials for the production of a wide range of products, from clothing and carpets to industrial textiles and composites. As a key component of the broader 54 Man-made filaments industry, the 550119 product category contributes significantly to international trade and economic development.

Production process

The production of synthetic filament tow under HS code 550119 typically involves the extrusion of molten nylon or other polyamide polymers through a spinneret, forming continuous filaments. These filaments are then drawn, cooled, and gathered into a tow, which is a loose, untwisted bundle of parallel filaments. The tow may undergo further processing, such as crimping or cutting, to create staple fibers or other intermediate products used in textile manufacturing.

Production inputs

The main inputs required for the production of 550119 synthetic filament tow include nylon or other polyamide polymers, which serve as the raw material. Additionally, specialized machinery, such as extruders, spinnerets, and drawing equipment, is essential for the manufacturing process. Energy sources, such as electricity or natural gas, are also necessary to power the production facilities.

Production outputs

The primary output of HS code 550119 is synthetic filament tow, which is then used as an input for various downstream industries. This tow may be further processed into 5503 Synthetic staple fibres, 5501 Synthetic filament tow, or 5402 Synthetic filament yarn, all of which are classified under different HS codes. These intermediate products are then consumed by the textile, apparel, and industrial sectors to manufacture a wide range of final goods, including clothing, carpets, and composite materials.

Revisions to 550119
