Import Tips
• Verify polymer composition meets 95% ethylene monomer requirement per subheading notes to avoid reclassification
• Provide material test certificates confirming rigidity and ethylene polymer content during customs entry
• Avoid common pitfalls like misdeclaring flexible HDPE as rigid, which shifts to 3917.31 or 3917.39
