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
