High-Purity Silica Filament Woven Fabric
This woven fabric is made from silica filaments with over 93% silica content, classified under HTS 7019.62.90.30 as a mechanically bonded closed fabric of rovings. It is designed for high-temperature applications due to its exceptional thermal resistance and low thermal expansion.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If silica content is 93% or less
Lower silica content fabrics fall under other subheadings within 7019.62.90, changing the specific statistical suffix.
If not meeting fused silica or mineral wool definitions
Non-compliant mineral wools without required silica or oxide levels are classified as mineral wools in heading 6806.
If sold as woven fabric of filament yarn rather than rovings
Woven fabrics from filament yarns (not rovings) are directed to 7019.40, based on fiber assembly form.

Import Tips & Compliance
• 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
