Subheadings
Products classified under HTS 3921.19.00
Cellular PVC Foam Board Sheets
Rigid cellular polyvinyl chloride (PVC) foam boards used for signage, displays, and construction panels. Classified under HTS 3921.19.00 as cellular sheets of other plastics (PVC predominates over 95% per subheading note (a)(1)). The foamed structure offers high strength-to-weight ratio and weather resistance.
Cross-Linked Polyolefin Foam Sheets
Chemically cross-linked cellular polyolefin foam sheets used for insulation and gaskets, classified in 'Other' per subheading note (a)(3) for chemically modified polymers. Under HTS 3921.19.00 as cellular sheets of other plastics. Provides superior durability and flexibility.
Cellular Polycarbonate Foam Panels
Lightweight cellular polycarbonate foam panels for aerospace and architectural glazing applications. HTS 3921.19.00 covers cellular sheets of polycarbonate as other plastics (not polyethylene/polystyrene/PU/etc.). Offers transparency and impact resistance.
Cellular Polyamide Foam Sheets
Nylon (polyamide) cellular foam sheets used for impact protection and vibration damping in machinery. HTS 3921.19.00 as cellular polyamide-6 or -6,6 (95%+ monomer per note (a)(1)). High toughness and abrasion resistance.
Cellular Acrylic Foam Tapes Base Sheets
Double-sided cellular acrylic polymer foam sheets serving as carrier for pressure-sensitive adhesive tapes. HTS 3921.19.00 for cellular acrylics not elsewhere specified. Used in automotive and electronics assembly.
Polyimide Cellular Foam Sheets
High-temperature resistant cellular polyimide foam sheets for aerospace thermal insulation. Classified HTS 3921.19.00 as other plastics cellular sheets. Maintains properties up to 300°C.
Expanded Polypropylene (EPP) Foam Sheets
These cellular sheets made from expanded polypropylene are lightweight and impact-resistant, commonly used for protective packaging inserts. They fall under HTS 3921.19.00 as cellular plates, sheets, film, foil, or strip of other plastics, specifically non-polyethylene, non-polystyrene cellular polypropylene. The closed-cell structure provides excellent buoyancy and thermal insulation.
EVA Foam Exercise Mats
Closed-cell ethylene-vinyl acetate (EVA) copolymer foam mats for yoga and fitness, provided the ethylene monomer predominates per subheading note (a)(4). Falls under HTS 3921.19.00 as cellular sheets of other plastics. These mats offer cushioning, waterproofing, and portability for home workouts.
Foamed ABS Plastic Sheets
Cellular acrylonitrile-butadiene-styrene (ABS) copolymer foam sheets for automotive trim and prototyping. Classified under HTS 3921.19.00 as the predominant monomer (styrene typically) doesn't fit specific named subheadings. Durable and easily thermoformable.
PET Foam Core Sheets
Cellular polyethylene terephthalate (PET) foam sheets used as sandwich panel cores in composites. Under HTS 3921.19.00 as cellular polyester sheets of other plastics. Excellent stiffness and low weight for marine applications.
