HS v2017 Code: 550640

About fibres; synthetic staple fibres, of polypropylene, carded, combed or otherwise processed for spinning

HS code 550640 covers synthetic staple fibres of polypropylene that have been carded, combed, or otherwise processed for spinning. These fibres are a crucial component in the textile industry, providing a versatile and cost-effective material for a wide range of applications, from clothing and home furnishings to industrial textiles and nonwoven fabrics. As a major global producer and exporter of synthetic fibres, this industry plays a significant role in the international trade of textile raw materials.

Production process

The production of HS 550640 fibres typically involves several key steps. First, polypropylene resin is extruded into continuous filaments, which are then cut into short staple fibres. These fibres are then carded, a process that aligns and cleans the fibres, and may be further combed to remove any remaining impurities and improve the fibre's uniformity. Finally, the processed fibres are ready for spinning into yarns or incorporation into various textile products.

Production inputs

The main inputs required for the production of HS 550640 fibres include polypropylene resin, which serves as the raw material, as well as specialized machinery for extrusion, cutting, carding, and combing. Additionally, energy sources, such as electricity or natural gas, are needed to power the production equipment. The industry may also rely on various chemical additives, such as antistatic agents or flame retardants, to enhance the performance of the final fibres.

Production outputs

The primary output of HS 550640 is synthetic staple fibres of polypropylene, which are then used as a raw material in the production of a wide range of textile products. These fibres may be consumed by industries producing 550320 Fibres; synthetic staple fibres, of polyesters or 550330 Fibres; acrylic or modacrylic, synthetic staple, as well as manufacturers of 560311 Nonwovens; of man-made filaments, weighing not more than 25 g/m² and 560312 Nonwovens; of man-made filaments, weighing more than 25 g/m² nonwoven fabrics.
