Import Tips
• Verify filament diameter and weight via lab testing to confirm classification; discrepancies can lead to reclassification
• Provide manufacturer specs on colorants used, as they must not alter the glass fiber nature per Chapter 70 notes
• Ensure documentation distinguishes from yarn or woven fabrics to avoid misclassification under 7019.10-7019.40
