Carbodimide PE Blend Pellets from Japan
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.

Import Tips
• 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
