About HS Code 390320
This code covers styrene-acrylonitrile (SAN) copolymers in their primary forms, typically pellets or granules. SAN is a transparent, rigid, and chemical-resistant engineering thermoplastic, offering better heat resistance and mechanical properties than general-purpose polystyrene. It's a niche but important material in international trade, primarily exported by specialized chemical producers and imported by manufacturers of household goods (e.g., blender jars), automotive parts (e.g., instrument panels), medical devices, and transparent packaging. Key trade aspects include the demand for high-performance transparent plastics, the impact of acrylonitrile monomer prices, and the need for specific grades tailored to end-use applications requiring clarity and chemical resistance.
Products Under This Code
SAN pellets, high-clarity SAN, UV-stabilized SAN, food-contact SAN, injection molding SAN, extrusion grade SAN, chemical-resistant SAN
Real World Examples
Trinseo Tyril SAN, INEOS Styrolution Luran SAN, LG Chem SAN, Chi Mei Polylac SAN, Toray SAN
Common Misclassification
Can be confused with 390319 (other polystyrene) if the acrylonitrile component is overlooked, or with 390330 (ABS copolymers) if the butadiene rubber phase is not present.
Products Classified Under 3903.20
Industry
This code belongs to the Plastics & Rubber industry.
Trade Overview
South Korea, Germany, and USA are major exporters, with China, USA, and European countries being top importers.
