Vinyl chloride polymers; waste, parings and scrap

HS code 391530 covers vinyl chloride polymers, which are a versatile group of thermoplastic materials with a wide range of applications. These polymers are widely used in the manufacturing of various products, from construction materials to medical devices, making them an essential component of many industries. The global vinyl chloride polymer market is expected to continue growing, driven by increasing demand from various end-use sectors, underscoring the importance of this industry within the broader economy.

Vinyl chloride polymers are typically produced through a polymerization process, where vinyl chloride monomers are combined to form long polymer chains. This process can be carried out using various techniques, such as suspension polymerization, emulsion polymerization, or bulk polymerization, depending on the specific requirements of the final product. The resulting polymer is then processed into various forms, such as sheets, films, or molded parts, using methods like extrusion, injection molding, or calendering.

The main inputs required for the production of vinyl chloride polymers include vinyl chloride monomers, which are typically derived from the petrochemical industry, as well as various additives and processing aids, such as stabilizers, plasticizers, and fillers. Additionally, the industry relies on specialized machinery and equipment, including polymerization reactors, extruders, and molding machines, to transform the raw materials into the final products.

The primary output of HS code 391530 is vinyl chloride polymers, which are then used in the manufacture of a wide range of products, including 392010 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 392020 Plates, sheets, film, foil and strip, of plastics, cellular, 392030 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, and 392041 Other plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials: Of vinyl chloride. These polymers are also used in the production of pipes, fittings, packaging materials, and various consumer goods.
