Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing colorants or dyes
Colored versions of silica filament fabrics fall under the colored subheading.
If supplied as yarns rather than fabricated
Unwoven rovings or yarns classify under yarn headings before fabric production.
If coated with textile plastics for reinforcement
Textile fabric coated with plastics shifts to Chapter 59 for coated materials.

Import Tips & Compliance
• Provide manufacturer specs confirming >93% silica and roving structure for customs compliance
• Label as 'not colored' with evidence to prevent reclassification to colored variants
