Polycarbonates; in primary forms

HS v2017 Code: 390740

About polycarbonates; in primary forms

HS code 390740 covers the classification of polycarbonates in their primary forms. Polycarbonates are a type of thermoplastic polymer known for their exceptional impact resistance, optical clarity, and dimensional stability. This industry plays a crucial role in the production of a wide range of consumer and industrial products, contributing significantly to the global economy.

Production process

The primary production technique for polycarbonates involves a step-wise polymerization process. This typically starts with the reaction of bisphenol A and phosgene, which produces a polycarbonate resin. The resin is then extruded, molded, or otherwise processed into the desired primary forms, such as pellets, sheets, or films.

Production inputs

The main inputs required for the production of polycarbonates include bisphenol A, phosgene, and various additives such as stabilizers, lubricants, and colorants. Specialized machinery, such as extruders, injection molding machines, and compounding equipment, are also essential for the manufacturing process.

Production outputs

The primary outputs of this industry are polycarbonate resins and products in their primary forms, such as pellets, sheets, and films. These outputs are then consumed by a wide range of industries, including 392010 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials, 701910 (Glass fibres (including glass wool) and articles thereof (for example, yarn, woven fabrics)), and 853710 Boards, panels, consoles, desks, cabinets and other bases, equipped with two or more apparatus of heading 8535 or 8536, for electric control or the distribution of electricity, including those incorporating instruments or apparatus of Chapter 90, other than switching apparatus of heading 8517.
