About yarn; (not sewing thread), of synthetic staple fibres, mixed mainly or solely with fibres (other than wool, fine animal hair or cotton), n.e.c. in heading no. 5509, not put up for retail sale

HS code 550999 covers a wide range of synthetic yarn products that are primarily used in the textile and apparel industries. These yarns are made from a blend of synthetic staple fibers, excluding wool, fine animal hair, and cotton, and are not put up for retail sale. This industry plays a crucial role in the global textile supply chain, providing essential raw materials for the production of a variety of fabrics and garments.

Production process

The production of synthetic yarn under HS code 550999 typically involves a multi-step process. First, the synthetic staple fibers are spun into continuous filaments using techniques such as melt spinning or wet spinning. These filaments are then twisted or plied together to create the desired yarn structure. Depending on the specific application, the yarns may undergo additional processing, such as texturizing, to impart certain properties like increased bulk or stretch.

Production inputs

The main inputs required for the production of synthetic yarn under HS code 550999 include synthetic staple fibers, such as polyester, nylon, or acrylic. These raw materials are typically sourced from petrochemical manufacturers or specialized fiber producers. Additionally, the industry relies on specialized machinery, such as spinning frames, twisting machines, and texturizing equipment, to transform the raw materials into the final yarn products.

Production outputs

The synthetic yarns produced under HS code 550999 are primarily used in the manufacture of a wide range of textile products, including 540700 Woven fabrics of synthetic filament yarn and 540769 Other woven fabrics of synthetic filament yarn. These yarns may also be used in the production of 550320 Synthetic staple fibres, not carded, combed or otherwise processed for spinning and 550410 Artificial staple fibres, not carded, combed or otherwise processed for spinning, which are further processed into various textile goods.
