Import Tips

• Verify yarn denier/decitex and twist measurement (≤50 turns/m) with lab testing to confirm classification under 5402.49.91

• Provide manufacturer's technical data sheet specifying single yarn construction and synthetic polymer type for customs entry

• Avoid common pitfalls like misdeclaring as textured yarn, which shifts to 5402.33; ensure no retail packaging
