HS v2017 Code: 550319

About fibres; synthetic staple fibres, of nylon or other polyamides other than aramids, not carded, combed or otherwise processed for spinning

HS code 550319 covers synthetic staple fibers made from nylon or other polyamides, excluding aramids. These fibers are an essential raw material for the textile industry, providing the foundation for a wide range of fabrics and garments. As a key component in the global supply chain, the production and trade of these fibers play a significant role in the broader economy, supporting industries such as apparel, home furnishings, and industrial textiles.

Production process

The production of synthetic staple fibers under HS code 550319 typically involves a multi-step process. First, the raw materials, which are typically petrochemical-based polymers, are melted and extruded through spinnerets to form continuous filaments. These filaments are then cut into short, uniform lengths to create the staple fibers. The fibers may undergo additional processing, such as drawing, crimping, or heat-setting, to impart desired properties like strength, elasticity, or luster.

Production inputs

The main inputs required for the production of synthetic staple fibers under HS code 550319 include petrochemical-based polymers, such as nylon or other polyamides, as well as specialized machinery for the extrusion, cutting, and processing of the fibers. Energy sources, such as electricity or natural gas, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce to operate the equipment and ensure quality control.

Production outputs

The primary output of HS code 550319 is synthetic staple fibers made from nylon or other polyamides, excluding aramids. These fibers are then consumed by various downstream industries, such as 550320 Fibres; synthetic staple fibres, of polyesters for the production of fabrics, 540233 Fabrics; woven, of synthetic filament yarn, including those made of materials of heading 54.04 for the manufacture of apparel, and 560314 Nonwovens; of man-made filaments, whether or not impregnated, coated, covered or laminated for the creation of industrial textiles and other non-woven products.
