Import Tips
• Include manufacturer's specification confirming CAS registry match to HTS-named polymer for binding ruling requests
• Segregate from generic PE resins to avoid 3901 classification challenges
• Document end-use as polymer additive, not finished article, preventing 3926 misclassification
