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

HS code 551110 covers the production and sale of synthetic staple fiber yarn, a critical component in the global textile and apparel industry. This yarn is composed of at least 85% synthetic fibers by weight and is packaged for retail sale. The demand for this type of yarn is driven by its versatility, durability, and cost-effectiveness, making it a popular choice for a wide range of textile applications, from clothing and home furnishings to industrial textiles.

The production of synthetic staple fiber yarn (551110) typically involves several key steps. First, synthetic fibers such as polyester, nylon, or acrylic are extruded and cut into short, uniform lengths known as staple fibers. These fibers are then cleaned, blended, and carded to align them in a parallel orientation. The aligned fibers are then drawn and twisted together to form the continuous yarn, which is then wound onto bobbins or spools for packaging and distribution.

The main inputs required for the production of synthetic staple fiber yarn (551110) include synthetic fibers, such as polyester, nylon, or acrylic; spinning and twisting machinery; and packaging materials. The quality and consistency of the synthetic fibers are critical, as they directly impact the strength, durability, and appearance of the final yarn product. Additionally, specialized equipment for fiber preparation, spinning, and winding is necessary to ensure efficient and high-quality yarn production.

The primary output of HS code 551110 is synthetic staple fiber yarn, which is then consumed by a variety of downstream industries. This yarn is commonly used in the production of 520100 Woven fabrics and 600300 Knitted or crocheted fabrics, which are then further processed into clothing, home textiles, and industrial applications. The yarn produced under this code may also be used in the manufacture of 560311 Nonwovens, which have a wide range of applications, including filtration, insulation, and personal protective equipment.
