Import Tips
• Verify yarn tenacity exceeds 9.0 cN/tex and decitex ≤920 with lab certification to confirm HTS 5402.11.30.10 classification
• Provide manufacturer's twist test data (<5 turns/m) and aramid polymer specs in entry documentation to avoid misclassification
• Ensure bulk industrial packaging; retail-put-up shifts to Chapter 55
