Import Tips

• Verify filament diameter and weight via lab testing to confirm classification under 7019.69.40.21; deviations may shift to other subheadings

• Provide mill test certificates documenting glass composition and bonding method to avoid misclassification as woven fabrics

• Ensure proper labeling for industrial use to prevent reclassification as consumer goods under Chapter 94
