Subheadings
Products classified under Tariff item 3903.1
EPS Raw Expanded Beads
Pre-foamed expandable polystyrene beads in granular form, retaining a blowing agent and intended for rotational molding or foam block production. They are in primary forms as defined by Chapter 39 and remain expansible, meeting the tariff item's scope.
3903.11.00Gray Flame-Retardant EPS Beads
Gray expandable polystyrene beads containing a flame-retardant additive (HBCD) for construction insulation foam. The additive does not alter the primary expandable polymer status, so they remain classified under this tariff item.
3903.11.00High-Index EPS Beads H100
High-expansion-index polystyrene beads (H100) for thin-walled foam molding. They are in primary expandable form with a blowing agent, suitable for steam chest molding, and meet the tariff item's definition.
3903.11.00Pentane-Infused EPS Pellets
Polystyrene pellets impregnated with pentane as a blowing agent for steam expansion in foam molding. They are in primary forms and remain expansible, distinguishing them from rigid polystyrene.
3903.11.00Recyclable EPS Expandable Pellets
Recycled-content expandable polystyrene pellets for sustainable foam production. They meet polymer content rules and remain in primary expandable form, so they are classified under this tariff item.
3903.11.00Styrofoam Beads EPS
Expandable polystyrene beads (Styrofoam) for molding into foam products, containing pentane as a blowing agent. They are unexpanded or pre-expanded but remain in primary form and are expansible.
3903.11.00Unexpanded EPS Granules
Unexpanded polystyrene granules containing a blowing agent for in-plant expansion into foam blocks. They are in primary forms and are expansible, meeting the tariff item's precise scope.
3903.11.00White EPS Pre-Puff Beads
White expandable polystyrene pre-puff beads for lightweight foam packaging inserts. They are in primary form before final expansion and molding, and remain expansible.
3903.19.00Atactic 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.
3903.19.00Crystal 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.
3903.19.00Extrusion 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.
3903.19.00General 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.
3903.19.00High 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.
3903.19.00Injection Molding Polystyrene Resin
Injection molding polystyrene resin is a high-flow polystyrene designed for precision injection molding of household items, supplied in primary form. It falls under tariff item 3903.19.00 as 'other' polystyrene, as it is not expandable and does not contain significant comonomers. This resin offers balanced viscosity for complex thin-wall parts, making it suitable for various consumer products.
3903.19.00Polystyrene 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.
3903.19.00Syndiotactic Polystyrene Pellets (SPS)
Syndiotactic polystyrene pellets (SPS) are a crystalline form of polystyrene produced by stereospecific polymerization, 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. SPS is used in high-heat engineering applications, such as automotive components and electrical connectors.
