About vinyl chloride, other halogenated olefin polymers; non-plasticised poly(vinyl chloride), in primary forms, mixed with other substances

HS code 390421 covers the import and export of vinyl chloride and other halogenated olefin polymers, specifically non-plasticized poly(vinyl chloride) (PVC) in primary forms, mixed with other substances. This industry is a crucial component of the broader chemical and plastics manufacturing sectors, providing essential raw materials for a wide range of downstream applications across various industries.

Production process

The production of the materials covered by HS code 390421 typically involves the polymerization of vinyl chloride monomers. This process can be carried out through suspension, emulsion, or bulk polymerization techniques, depending on the desired properties of the final product. The resulting PVC resin is then compounded with various additives, such as stabilizers, lubricants, and fillers, to create the desired formulation for specific applications.

Production inputs

The main inputs required for the production of the materials covered by HS code 390421 include vinyl chloride monomer, which is typically derived from the petrochemical industry, as well as a range of additives and processing aids. Specialized production equipment, such as polymerization reactors, compounding extruders, and molding machines, are also essential for the manufacturing process.

Production outputs

The primary outputs of the industry covered by HS code 390421 are non-plasticized PVC resins, which can be used in a variety of applications, including construction materials, packaging, automotive components, and electrical insulation. These PVC resins may be further processed or combined with other materials to create a wide range of finished products. Other related HS codes that may consume the output of this industry include 390410 Polyvinyl chloride, not mixed with any other substances, 390422 (Vinyl chloride, other halogenated olefin polymers; plasticised poly(vinyl chloride), in primary forms, mixed with other substances), and 390430 (Vinyl chloride, other halogenated olefin polymers; non-plasticised poly(vinyl chloride), in primary forms, not mixed with other substances).
