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 and apparel industries, providing strength, durability, and versatility in a wide range of products. 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 650000 Textiles and textile articles and 940000 Furniture; bedding, mattresses, mattress supports, cushions and similar stuffed furnishings; lamps and lighting fittings, not elsewhere specified or included; illuminated signs, illuminated name-plates and the like; prefabricated buildings.

Production process

The production of synthetic staple fibers under HS code 550319 typically involves a multi-step process. First, the raw materials, such as nylon or other polyamide 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 characteristics like increased strength, improved texture, or enhanced dimensional stability.

Production inputs

The main inputs required for the production of synthetic staple fibers under HS code 550319 include nylon or other polyamide polymers, which serve as the primary raw material. Additionally, specialized machinery, such as extruders, cutters, and finishing equipment, is necessary to transform the raw materials into the final fiber products. Energy sources, such as electricity or natural gas, are also crucial inputs for the manufacturing process.

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 and 550330 Fibres; acrylic or modacrylic synthetic staple fibres, which use them as raw materials for the production of textiles, apparel, and other fiber-based products. The fibers may also be used in the manufacture of 940430 Sleeping bags, 940490 Mattress supports; articles of bedding and similar furnishing and other household items.
