Styrene polymers; waste, parings and scrap

HS code 391520 covers the trade of styrene polymers, which are a versatile group of thermoplastic materials derived from the petrochemical industry. These polymers are widely used in a variety of applications, from packaging and construction to electronics and automotive components. As a key component in the global plastics supply chain, the styrene polymer industry plays a crucial role in supporting economic growth and development across numerous sectors.

The production of styrene polymers typically involves the polymerization of styrene monomers, which can be achieved through various techniques such as bulk, suspension, or emulsion polymerization. These processes transform the liquid styrene monomers into solid, moldable plastic resins that can be further processed and shaped into a wide range of products.

The primary raw material for the styrene polymer industry is styrene monomer, which is typically derived from the petrochemical industry. In addition to the styrene feedstock, the industry also relies on various additives, such as initiators, stabilizers, and modifiers, to enhance the properties and performance of the final products. Specialized machinery and equipment, including polymerization reactors, extruders, and injection molding machines, are also essential inputs for the efficient production of styrene polymers.

Styrene polymers produced under HS code 391520 can be further processed and transformed into a diverse range of products, including 392010 Plates, sheets, film, foil and strip, of polymers of styrene, 392030 Plates, sheets, film, foil and strip, of polymers of styrene, and 392190 Other plates, sheets, film, foil and strip, of plastics. These materials find applications in packaging, construction, electronics, and automotive industries, among others, making them an integral component of the global manufacturing and consumer goods supply chains.
