Atactic Polystyrene Granules
Atactic polystyrene granules are an amorphous, non-crystalline form of polystyrene supplied in primary form (granules). They are classified under tariff item 3903.19.00 as 'other' polystyrene, since they are not specifically named in any other subheading of heading 39.03. These granules are commonly used as blend modifiers to improve clarity and impact resistance in various plastic products.
Crystal Polystyrene Resin
Crystal polystyrene resin, also known as general purpose polystyrene (GPPS), is a clear, amorphous homopolymer of styrene supplied as resin pellets. It falls under tariff item 3903.19.00 as 'other' polystyrene in primary forms, since it is not expandable and does not contain significant comonomers. This resin is used for applications requiring optical clarity, such as CD cases and medical labware.
Extrusion Grade Polystyrene Pellets
Extrusion grade polystyrene pellets are a form of general purpose polystyrene (GPPS) optimized for extrusion processes, supplied in primary pellet form. They are classified under tariff item 3903.19.00 as 'other' polystyrene, as they are not expandable and do not contain significant comonomers. These pellets feature low gel content, making them suitable for producing films and sheets used in food packaging.
General Purpose Polystyrene Pellets (GPPS)
General purpose polystyrene pellets (GPPS) are a transparent homopolymer of styrene in pellet form, classified under tariff item 3903.19.00 as 'other' polystyrene in primary forms. This material is widely used for packaging, disposable cups, and other consumer goods where clarity and rigidity are required. It is not expandable and does not contain significant comonomers, distinguishing it from other styrene polymer subheadings.
High Impact Polystyrene Resin (HIPS)
High impact polystyrene resin (HIPS) is a copolymer of styrene and butadiene, with butadiene content typically under 5% by weight. It is classified under tariff item 3903.19.00 as 'other' polystyrene, since the styrene monomer unit predominates and the butadiene content is below the threshold for other subheadings. HIPS is used for applications requiring impact resistance, such as appliance housings and toys.
Polystyrene Compounding Base Resin
Polystyrene compounding base resin is a narrow molecular weight distribution polystyrene resin designed for compounding, imported in primary form. It is classified under tariff item 3903.19.00 as 'other' polystyrene, as it is not expandable and does not contain significant comonomers. This resin serves as a base for custom blends in electronics and packaging industries.
