HS v2022 Code: 390490

About vinyl chloride, other halogenated olefin polymers; n.e.c. in heading no. 3904

HS code 390490 covers a diverse range of vinyl chloride and other halogenated olefin polymers that are not classified elsewhere. These materials are essential components in a wide variety of industries, from construction and packaging to automotive and electronics. As a key part of the broader 3904 Polymers of vinyl chloride or of other halogenated olefins, in primary forms sector, this code plays a vital role in supporting global trade and economic development.

Production process

The production of vinyl chloride and other halogenated olefin polymers typically involves polymerization processes. Monomers, such as vinyl chloride, are combined under controlled temperature and pressure conditions to form long polymer chains. Specialized catalysts and additives may be used to influence the properties of the final product. Manufacturers employ a range of techniques, including suspension, emulsion, and bulk polymerization, to optimize the production process for different applications.

Production inputs

The main inputs required for the production of HS code 390490 materials include vinyl chloride and other halogenated olefin monomers, as well as various additives and catalysts. Manufacturers also rely on specialized equipment, such as polymerization reactors, extruders, and molding machines, to transform the raw materials into the desired polymer forms. Energy, water, and other utilities are also essential inputs for the production process.

Production outputs

The outputs of HS code 390490 are a diverse range of vinyl chloride and other halogenated olefin polymer products, which are then used as inputs for a variety of downstream industries. These polymers may be further processed into films, sheets, pipes, cables, and other finished goods classified under codes such as 3916 Monofilament of which any cross-sectional dimension exceeds 1 mm, rods, sticks and profile shapes, whether or not surface-worked but not otherwise worked, of plastics, 3917 (Tubes, pipes and hoses, and fittings therefor (for example, joints, elbows, flanges), of plastics), and 3920 Other plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, among others.
