About yarn; (not sewing thread), single, of synthetic staple fibres, containing 85% or more by weight of polyester, not put up for retail sale

HS code 550921 covers the classification of yarn made from synthetic staple fibers, specifically those containing 85% or more polyester by weight. This type of yarn is a crucial component in the textile and apparel industries, serving as a raw material for the production of a wide range of fabrics and garments. As a major player in the global supply chain, the 550921 yarn industry plays a significant role in the broader economy, supporting various downstream sectors and contributing to international trade.

Production process

The production of HS code 550921 yarn typically involves a multi-step process. First, synthetic polyester staple fibers are extruded and drawn to the desired thickness. These fibers are then carded and combed to align and clean them, before being spun into continuous yarn. The yarn may undergo additional processing, such as twisting or plying, to enhance its strength and quality. Finally, the finished yarn is wound onto bobbins or packages, ready for further textile manufacturing.

Production inputs

The main inputs required for the production of HS code 550921 yarn include polyester staple fibers, which serve as the primary raw material. Additionally, the industry relies on specialized machinery, such as extruders, carding machines, and spinning frames, to transform the raw materials into the final yarn product. Energy sources, such as electricity or natural gas, are also essential for powering the production equipment.

Production outputs

The primary output of the HS code 550921 yarn industry is, of course, the yarn itself. This yarn is then consumed by various downstream industries, including 550921 (Yarn; (not sewing thread), single, of synthetic staple fibres, containing 85% or more by weight of polyester, not put up for retail sale), 540761 Fabrics; woven, containing 85% or more by weight of non-textured polyester filaments, including monofilament of 67 decitex or more and of which the length of the component filaments does not exceed 5 mm, and 620342 Trousers, bib and brace overalls, breeches and shorts; men's or boys', of cotton, among others. The versatility of this polyester-rich yarn allows it to be utilized in a wide range of textile and apparel applications.
