About fibres; synthetic staple fibres, of synthetic materials n.e.c. in heading no. 5503, not carded, combed or otherwise processed for spinning

HS code 550390 covers a wide range of synthetic staple fibers that are not carded, combed, or otherwise processed for spinning. These fibers are an essential component in the production of various textile products, including clothing, upholstery, and industrial applications. The global synthetic staple fiber market is a significant contributor to the broader textile industry, with growing demand driven by factors such as population growth, urbanization, and the increasing preference for synthetic fabrics.

Production process

The production of synthetic staple fibers under HS code 550390 typically involves a multi-step process. First, the raw materials, such as polyester, nylon, or acrylic, are melted and extruded through spinnerets to form continuous filaments. These filaments are then cut into short, staple-length fibers, which are subsequently processed to achieve the desired properties, such as crimp, luster, and cross-sectional shape. The fibers may undergo additional treatments, such as drawing, heat-setting, or chemical finishing, to enhance their performance characteristics.

Production inputs

The main inputs required for the production of synthetic staple fibers under HS code 550390 include petrochemical-based raw materials, such as polyester, nylon, or acrylic resins. These raw materials are typically sourced from large-scale chemical manufacturers. Additionally, the production process requires specialized machinery, including extruders, cutters, and fiber-processing equipment. Energy, water, and various chemical additives, such as lubricants and antistatic agents, are also essential inputs for this industry.

Production outputs

The primary output of HS code 550390 is synthetic staple fibers, which are then used as inputs for a wide range of textile and non-textile applications. These fibers may be consumed by manufacturers of 550320 Fibres; synthetic staple fibres, of polyesters, 550330 Fibres; synthetic staple fibres, of acrylic or modacrylic, or 550340 Fibres; synthetic staple fibres, of polypropylene, among others, who further process them into yarns, fabrics, and finished products. The versatility of these synthetic staple fibers allows them to be used in a variety of industries, including apparel, home textiles, automotive, and industrial applications.
