Monofilament n.e.c. in heading no 5404; of 67 decitex or more and of which no cross-sectional dimension exceeds 1mm

HS code 540419 covers a specific type of monofilament, which is a single, continuous synthetic fiber used in a variety of applications. This industry plays a crucial role in the broader textile and manufacturing sectors, providing essential raw materials for the production of fabrics, ropes, fishing lines, and other industrial products. The demand for these monofilaments is driven by their unique properties, such as high strength, durability, and versatility, making them an indispensable component in many supply chains.

The production of monofilaments under HS code 540419 typically involves an extrusion process. Molten polymer, such as polyamide or polyester, is forced through a die with small orifices to create continuous filaments. These filaments are then cooled, drawn, and wound onto spools or bobbins. The precise control of parameters like temperature, pressure, and draw ratio is essential to ensure the desired diameter, strength, and other physical properties of the final monofilament product.

The main inputs required for the production of HS code 540419 monofilaments include polymer resins, such as polyamide or polyester, as well as specialized machinery and equipment for the extrusion and drawing processes. Additionally, energy sources, such as electricity or natural gas, are necessary to power the production facilities. The availability and quality of these raw materials and infrastructure are crucial factors in the competitiveness of this industry.

Monofilaments produced under HS code 540419 are primarily used as inputs for the manufacture of 540710 Woven fabrics of synthetic filament yarn and 560290 Felt, whether or not impregnated, coated, covered or laminated. These monofilaments may also be used in the production of 560312 Nonwovens, whether or not impregnated, coated, covered or laminated, of man-made filaments: Weighing more than 25 g/m² and 560410 Rubber thread and cord, textile covered; textile yarn, and strip and the like of heading 5404 or 5405, impregnated, coated, covered or sheathed with rubber or plastics. The versatility of these monofilaments makes them an essential component in a wide range of textile and industrial applications.
