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 crucial segment of the synthetic textile industry, encompassing a wide range of synthetic staple fibers that are not carded, combed, or otherwise processed for spinning. These fibers play a vital role in the production of various textile products, from apparel to home furnishings, and are an integral part of the global textile supply chain.

Production process

The production of synthetic staple fibers under HS code 550390 typically involves a multi-step process. First, synthetic polymers, such as polyester or nylon, are extruded through spinnerets to form continuous filaments. These filaments are then cut into short, discrete lengths, known as staple fibers. The fibers may undergo further processing, such as drawing, crimping, or heat-setting, to impart desired properties like strength, elasticity, or luster.

Production inputs

The primary inputs for the production of synthetic staple fibers under HS code 550390 include synthetic polymers, such as 540100 Polyamides, 540200 Polyesters, and 540300 Artificial filament tow. Additionally, specialized machinery, such as extruders, cutters, and fiber-processing equipment, are essential for the manufacturing process. Energy sources, such as electricity or natural gas, and water for cooling and cleaning are also important inputs.

Production outputs

The synthetic staple fibers produced under HS code 550390 are used in a wide range of textile applications, including the manufacture of 550320 Synthetic staple fibres, of polyesters, 550330 Synthetic staple fibres, of acrylic or modacrylic, and 550340 Synthetic staple fibres, of polypropylene. These fibers are often blended with other textile materials, such as natural fibers, to create a variety of fabrics and end-products.
