Products classified under Tariff item 3921.19.00
Battery Grade PP Microporous Membrane
>- High-purity microporous polypropylene membrane used as a lithium-ion battery separator, with controlled pore distribution. This is a cellular (microporous) sheet of polypropylene, which is not one of the named plastics in other subheadings of heading 39.21, so it falls under 3921.19.00 as "of other plastics."
Breathable PE Diaper Backing Film
>- Microporous polyethylene film used as a soft, breathable backsheet in disposable diapers. This is a cellular (microporous) sheet of polyethylene, which is not one of the named plastics in other subheadings of heading 39.21, so it falls under 3921.19.00 as "of other plastics."
Cellular Acrylic Foam Tapes Base Sheets
>- Double-sided cellular acrylic polymer foam sheets used as a carrier for pressure-sensitive adhesive tapes. These sheets are cellular (foamed) and made of acrylic polymer, which is not one of the named plastics in other subheadings of heading 39.21, so they fall under tariff item 3921.19.00 as "of other plastics."
Cellular Polyamide Foam Sheets
>- Cellular polyamide (nylon) foam sheets used for impact protection and vibration damping in machinery. Polyamide is not one of the named plastics in other subheadings of heading 39.21, and the cellular structure qualifies these sheets for classification under 3921.19.00 as "of other plastics."
Cellular Polycarbonate Foam Panels
>- Lightweight cellular polycarbonate foam panels used for aerospace and architectural glazing applications. Polycarbonate is not one of the named plastics in other subheadings of heading 39.21, and the cellular structure qualifies these panels for classification under 3921.19.00 as "of other plastics."
Cellular PVC Foam Board Sheets
>- Rigid cellular polyvinyl chloride (PVC) foam boards used for signage, displays, and construction panels. PVC is not one of the named plastics in other subheadings of heading 39.21, and the cellular structure qualifies these boards for classification under 3921.19.00 as "of other plastics."
Cleanroom Microporous PE Curtain Film
>- Microporous polyethylene strip film for cleanroom strip curtains, maintaining air pressure differentials. This is a cellular (microporous) sheet of polyethylene, which is not one of the named plastics in other subheadings of heading 39.21, so it falls under 3921.19.00 as "of other plastics."
Cross-Linked Polyolefin Foam Sheets
>- Chemically cross-linked cellular polyolefin foam sheets used for insulation and gaskets. These sheets are made of polyolefin (e.g., polyethylene or polypropylene) that has been chemically modified through cross-linking, and per subheading note 1(a)(3), chemically modified polymers are classified in the "Other" subheading, which corresponds to 3921.19.00.
EVA Foam Exercise Mats
>- Closed-cell ethylene-vinyl acetate (EVA) copolymer foam mats for yoga and fitness. The ethylene monomer predominates by weight over vinyl acetate, and since no single comonomer unit contributes 95% or more, the copolymer is classified under the "Other" subheading per subheading note 1(a)(4), which corresponds to 3921.19.00.
Expanded Polypropylene (EPP) Foam Sheets
>- Expanded polypropylene (EPP) foam sheets, lightweight and impact-resistant, used for protective packaging inserts. Polypropylene is not one of the named plastics in other subheadings of heading 39.21, and the cellular structure qualifies these sheets for classification under 3921.19.00 as "of other plastics."
Foamed ABS Plastic Sheets
>- Foamed acrylonitrile-butadiene-styrene (ABS) copolymer sheets for automotive trim and prototyping. ABS is a copolymer where no single monomer unit contributes 95% or more, and per subheading note 1(a)(4), it is classified in the "Other" subheading, which corresponds to 3921.19.00.
Food Packaging Microporous PP Film
>- Microporous polypropylene film for fresh produce packaging, enabling modified atmosphere with ethylene control. This is a cellular (microporous) sheet of polypropylene, which is not one of the named plastics in other subheadings of heading 39.21, so it falls under 3921.19.00 as "of other plastics."
Housewrap Microporous Polypropylene Film
>- Microporous polypropylene breathable film used in construction housewrap for moisture vapor transmission. This is a cellular (microporous) sheet of polypropylene, which is not one of the named plastics in other subheadings of heading 39.21, so it falls under 3921.19.00 as "of other plastics."
PET Foam Core Sheets
>- Cellular polyethylene terephthalate (PET) foam sheets used as sandwich panel cores in composites. PET is a polyester, and since there is no specific subheading for cellular polyester in heading 39.21, these sheets are classified under 3921.19.00 as "of other plastics."
Polyimide Cellular Foam Sheets
>- High-temperature resistant cellular polyimide foam sheets for aerospace thermal insulation. Polyimide is not one of the named plastics in other subheadings of heading 39.21, and the cellular structure qualifies these sheets for classification under 3921.19.00 as "of other plastics."
