Carbodimide PE Blend Pellets
Carbodimide PE blend pellets are thermoplastic granules under HTS 3911.90.15.00, featuring the specified homopolymer of 2,4-diisocyanate-1,3,5-tris(1-methylethyl) with polyethylene, where aromatic units predominate by weight. Used as hydrolysis stabilizers in TPU films and coatings for automotive and textile applications. Primary form classification applies as these are unmodified polymer pellets ready for compounding.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If reclassified as polyethylene copolymers with minor carbodiimide modification
Copolymers where polyethylene monomer predominates (>50% by weight) fall under 3901.40 per subheading note (a)(4) predominance rule over specific 3911.90.15.
If for other thermoplastic aromatic monomer products not matching exact description
Broader 'other' thermoplastic category in 3911.90.19 catches similar resins without the precise carbodiimide-polyethylene structure specified in .15.
If imported as non-primary form plates, sheets, or profiles
Shifts from primary forms (39.11) to plates/sheets/film (3920) based on physical form and state of completion, not polymer type.

Import Tips & Compliance
• Provide monomer analysis confirming aromatic content meets 95% threshold for named polymer per Chapter 39 subheading note (a)(1)
• Ensure packaging specifies 'primary forms' to avoid classification as articles (3926)
• Watch for CBP requests for FTIR spectra verifying polyethylene homopolymer blend
