Products classified under Tariff item 3903.1

3903.11.00

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.

3903.11.00

Gray 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.

3903.11.00

High-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.

3903.11.00

Pentane-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.

3903.11.00

Recyclable 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.

3903.11.00

Styrofoam 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.

3903.11.00

Unexpanded 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.

3903.11.00

White 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.

3903.19.00

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.

3903.19.00

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.

3903.19.00

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.

3903.19.00

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.

3903.19.00

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.

3903.19.00

Injection 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.

3903.19.00

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.

3903.19.00

Syndiotactic 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.
