Silica Filament Plain Weave Fabric from China
This is a closed woven, plain weave fabric made from silica filaments with over 93% silica content, not colored, not coated or laminated. It falls under HTS 7019.63.40.30 as a mechanically bonded, non-colored silica filament fabric used primarily for high-temperature industrial applications. The high silica purity provides exceptional thermal resistance.

Import Tips
• Verify silica content certification exceeds 93% via lab analysis; ensure documentation proves plain weave construction without coatings; common pitfall is misclassifying as lower-silica glass fabric
