Import Tips & Compliance
• Verify yarn denier/decitex and twist measurement (≤50 turns/m) via lab testing to confirm HTS 5402.45.90 classification and avoid reclassification to twisted yarn headings
• Provide mill test certificates and yarn composition analysis (≥85% polyamide) as documentation for customs; common pitfall is mislabeling as sewing thread
• Ensure packaging is in large cones or beams (not retail put-up) to prevent shift to Chapter 55; declare exact linear density accurately
