Products classified under HTS 3908.90.70.00
Polyamide-11 Resin Pellets
Polyamide-11, derived from 11-aminoundecanoic acid, is a high-performance polyamide with over 95% monomer content by weight, classifying it under 3908.90.70.00 as 'Other' polyamides in primary forms like pellets. Used in engineering plastics for its flexibility and low moisture absorption.
Polyamide-12 Granules
Polyamide-12 resin granules, made from laurolactam with ≥95% single monomer unit, fall under HTS 3908.90.70.00 as other polyamides in primary forms. Ideal for 3D printing filament and flexible tubing due to low density.
Bio-based Polyamide-4,10 Resin
Bio-sourced polyamide-4,10 resin beads with ≥95% monomer units from sebacic acid, falling under HTS 3908.90.70.00 as other polyamides in primary forms. Sustainable alternative for engineering applications.
Polyamide-6I/6T Copolymer Pellets
Semi-aromatic copolyamide 6I/6T pellets where no single monomer predominates ≥95%, classified under 3908.90.70.00 by predominant polyamide monomer per subheading rules. High-temperature applications in electronics.
High-Viscosity Polyamide-610
Polyamide-610 pellets with high melt viscosity from hexamethylenediamine and sebacic acid, ≥95% monomers, classified 3908.90.70.00 as other polyamides. Applications in monofilaments and bristles.
Low-Temperature Polyamide Copolymer
Engineering-grade low-temperature polyamide copolymer pellets under 3908.90.70.00, classified by predominant amide monomer. Designed for cold-flexible applications like seals.
Polyamide Elastomer Base Resin
Base resin for polyamide elastomers (e.g., Pebax type) in primary form, falling under 3908.90.70.00 as other polyamides before elastomeric processing. Used in sports shoe midsoles.
Polyphthalamide (PPA) Powder
Polyphthalamide (PPA) in powder form, a semi-aromatic polyamide not specifically named elsewhere, qualifies under 3908.90.70.00 for other polyamides in primary forms. High heat resistance makes it suitable for automotive under-hood parts.
Polyamide MXD6 Pellets
MXD6 polyamide pellets from meta-xylylene diamine, classified as 'Other' under 3908.90.70.00 since monomer content doesn't match specific polyamide subheadings. Used for high-barrier packaging films.
Transparent Polyamide Resin
Specialty transparent polyamide resin in primary pellet form, not meeting specific polyamide criteria, thus under 3908.90.70.00. Used for optical and film applications requiring clarity.
