Styrene polymers; acrylonitrile-butadiene-styrene (ABS) copolymers, in primary forms

HS code 390330 covers the production and trade of styrene polymers and acrylonitrile-butadiene-styrene (ABS) copolymers in their primary forms. These materials are widely used in the manufacturing of a diverse range of products, from automotive components to household appliances, making them an essential part of the global economy. Their versatility and durability have made them indispensable in various industries, contributing to their significant market demand worldwide.

The production of styrene polymers and ABS copolymers typically involves a multi-step process. Styrene monomers are first polymerized through processes like bulk, suspension, or emulsion polymerization to create polystyrene. For ABS, the polystyrene is then combined with acrylonitrile and butadiene monomers, which are polymerized and grafted together to form the ABS copolymer. The resulting polymers are then extruded or molded into their primary forms, such as pellets, sheets, or blocks, ready for further processing and manufacturing.

The main inputs required for the production of styrene polymers and ABS copolymers include styrene, acrylonitrile, and butadiene monomers, as well as various additives and catalysts. Specialized machinery, such as polymerization reactors, extruders, and molding equipment, are also essential for the manufacturing process. Additionally, energy sources, such as electricity or steam, are needed to power the production facilities.

The primary outputs of HS code 390330 are styrene polymers and ABS copolymers in their various primary forms, such as pellets, sheets, or blocks. These materials are then consumed by a wide range of industries, including 870323 Motor cars and other motor vehicles principally designed for the transport of persons, 841821 Refrigerators, household type, 940320 Medical, surgical, dental or veterinary furniture, and 950300 Tricycles, scooters, pedal cars and similar wheeled toys; dolls' carriages, among others.
