HS v2022 Code: 550330

About fibres; synthetic staple fibres, acrylic or modacrylic, not carded, combed or otherwise processed for spinning

HS code 550330 covers synthetic staple fibers made from acrylic or modacrylic polymers. These fibers are a crucial raw material for the textile industry, used in the production of a wide range of fabrics, including clothing, home furnishings, and industrial textiles. The global acrylic and modacrylic fiber market is expected to grow steadily in the coming years, driven by increasing demand from the apparel and home textile sectors, particularly in developing economies.

Production process

Acrylic and modacrylic staple fibers are typically produced through a process called wet or dry spinning. In wet spinning, the polymer is dissolved in a solvent and extruded through a spinneret, then coagulated in a chemical bath. Dry spinning involves melting the polymer and extruding it through a spinneret, with the fibers then solidifying in a stream of hot air. The fibers are then cut to the desired staple length, often between 38-102 mm, before being packaged for distribution.

Production inputs

The main inputs for the production of HS code 550330 fibers are acrylic or modacrylic polymers, which are typically derived from petroleum-based raw materials. Specialized machinery, such as extruders, spinnerets, and fiber-cutting equipment, are also essential for the manufacturing process. Additionally, various chemicals, including solvents and coagulants, may be required depending on the specific production method used.

Production outputs

The primary output of HS code 550330 is synthetic staple fibers, which are then consumed by the textile industry for the production of a wide range of fabrics and products. These fibers may be used in the manufacture of 550921 Yarn; of synthetic staple fibres, not put up for retail sale, 551120 Yarn; of synthetic staple fibres, containing 85% or more by weight of such fibres, put up for retail sale, and 551330 Fabrics; of synthetic staple fibres, containing less than 85% by weight of such fibres, mixed mainly or solely with cotton, of a weight not exceeding 170 g/m².
