Import Tips
• Document S-glass chemical composition (high silica content) and mechanical bonding process to distinguish from knitted types
• Include end-use declarations but note classification based on objective characteristics, not declared application
• Avoid pitfall of classifying as 7019.62 if open weave; measure thread count to confirm closed weave
