Import Tips

Verify silica content certification exceeding 93% via lab analysis to confirm HTS 7019.62.90.30 classification

Provide manufacturer's specs on filament composition and weaving process to avoid misclassification as general glass fiber fabrics

Ensure documentation distinguishes from lower-silica glass wools under 7019.10 to prevent duty reassessment
