Polyamides; polyamide-6, -11, -12, -6,6, -6,9, -6,10 or -6,12, in primary forms

HS code 390810 covers a range of synthetic polymers known as polyamides, which are widely used in various industries due to their exceptional strength, durability, and versatility. These materials, often referred to as nylons, play a crucial role in the global economy, finding applications in the production of textiles, automotive components, engineering plastics, and a multitude of other products that are essential to modern life.

Polyamides are typically produced through a polycondensation process, where dicarboxylic acids and diamines are combined under high temperature and pressure conditions. The specific type of polyamide (e.g., polyamide-6, polyamide-11) is determined by the choice of monomers used in the reaction. The resulting polymer is then extruded, cooled, and cut into pellets or granules, which can be further processed into a wide range of end-products.

The primary inputs for the production of polyamides under HS code 390810 include petrochemical-based raw materials such as adipic acid, hexamethylenediamine, and caprolactam. Additionally, specialized machinery and equipment, such as extruders, reactors, and molding machines, are essential for the manufacturing process. Energy sources, such as electricity and steam, are also required to power the production facilities.

The polyamides produced under HS code 390810 are used in the manufacture of a diverse range of products, including 540720 Woven fabrics obtained from strip or the like, 540710 Woven fabrics of synthetic filament yarn, 392010 Plates, sheets, film, foil and strip, of polymers of ethylene, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, and 870840 Gear boxes and parts thereof. These polyamide-based materials are valued for their strength, durability, and resistance to wear and tear, making them indispensable in many industries.
