Elastomeric monofilament; of 67 decitex or more and of which no cross-sectional dimension exceeds 1mm

HS code 540411 covers elastomeric monofilaments, which are a critical component in a wide range of industries. These high-performance synthetic fibers offer exceptional elasticity, strength, and durability, making them essential for applications such as clothing, automotive components, and industrial textiles. As a key input for numerous manufacturing sectors, the elastomeric monofilament industry plays a vital role in supporting global trade and economic growth.

The production of elastomeric monofilaments under HS code 540411 typically involves a multi-step process. First, raw materials such as polyurethane or other synthetic polymers are melted and extruded through a spinneret to form continuous filaments. These filaments are then drawn, stretched, and heat-treated to impart the desired level of elasticity and tensile strength. Finally, the monofilaments may undergo additional processing, such as texturing or coating, to meet the specific requirements of end-users.

The main inputs required for the production of elastomeric monofilaments under HS code 540411 include synthetic polymers, such as polyurethane, as well as specialized machinery for extrusion, drawing, and heat treatment. Additionally, energy sources, such as electricity or natural gas, are needed to power the production process. Skilled labor, quality control measures, and advanced manufacturing techniques are also crucial inputs for this industry.

Elastomeric monofilaments produced under HS code 540411 are primarily used as inputs for the manufacture of a wide range of products, including 540710 Woven fabrics of synthetic filament yarn for clothing and industrial textiles, 401699 Other articles of vulcanized rubber, and 870829 (Parts and accessories of bodies (including cabs) for motor vehicles). These versatile fibers are also used in the production of 560721 Twine, cordage, ropes and cables, of sisal or other textile fibers of the genus Agave, 591190 Textile products and articles, for technical uses, specified in Note 7 to this Chapter, and other specialized industrial applications.
