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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polyamide-6,6 with ≥95% monomer units
Polyamide-6,6 is specifically named in 3908.10, taking precedence over 'Other' per subheading note (a)(1).
If copolymer predominated by different monomer
Polymers not meeting 95% threshold classified by predominant monomer unit under subheading note (a)(4).
If compounded with ≥33% plasticizers
Plasticized polyamide mixtures shift from primary forms (39.08) to plates/sheets/other shapes (3920.62).

Import Tips & Compliance
• Verify monomer content exceeds 95% by weight via lab testing to confirm classification under 3908.90.70.00
• Provide detailed chemical composition certificates to avoid misclassification as copolymers
• Ensure pellets are in primary form (not compounded) to prevent shifting to Chapter 39 heading 3920
