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
