Sewing thread; of synthetic filaments, whether or not put up for retail sale

HS code 540110 covers the production and trade of sewing thread made from synthetic filaments. This industry plays a crucial role in the global textile and apparel supply chain, providing an essential component for the manufacturing of a wide range of textile products. As a highly specialized segment of the broader synthetic fiber industry, the sewing thread sector contributes significantly to the overall economy through its involvement in international trade and its support for downstream industries.

The production of sewing thread under HS code 540110 typically involves a multi-step process. Synthetic filaments, such as polyester or nylon, are first extruded and drawn to the desired thickness. These filaments are then twisted together to form the thread, which may undergo additional processing steps like waxing, dyeing, or coating to enhance its properties. The finished thread is often wound onto spools or packaged for distribution to textile manufacturers and other end-users.

The main inputs required for the production of sewing thread under HS code 540110 include synthetic polymers, such as polyester or nylon, as well as specialized machinery for extrusion, twisting, and winding. Additionally, various chemicals and additives may be used to impart specific characteristics to the thread, such as increased strength, abrasion resistance, or color. The availability and cost of these raw materials and production equipment can significantly impact the competitiveness of this industry.

The primary output of the industry covered by HS code 540110 is sewing thread made from synthetic filaments. This thread is a critical input for the 520100 Cotton; not carded or combed and 520500 Cotton yarn, containing 85% or more by weight of cotton, not put up for retail sale industries, as well as the broader 540700 Woven fabrics of synthetic filament yarn, including woven fabrics obtained from materials of heading 54.04 and 550320 Synthetic staple fibers, not carded, combed or otherwise processed for spinning sectors. The sewing thread produced under this code is essential for the assembly and construction of a wide range of textile products, from apparel to upholstery and industrial applications.
