Import Tips
• Include color specification and stability testing docs, as coloring affects subheading under 'colored' provisions
• Label as 'silica filament fabric' with exact SiO2 percentage to differentiate from standard glass rovings
• Avoid bundling with non-silica materials to prevent reclassification as composite articles
