Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If narrow width not exceeding 30 cm
Narrower fabrics (<30 cm) have separate provisions outside the wide fabric subheadings.
If sold as panels or shapes, not continuous fabric
Cut-to-shape or worked glass fiber panels may classify as panels/articles in heading 6808.
If in container-like form for filtration
Glass articles like filter cartridges shift to heading 7010 if not qualifying as fabrics.

Import Tips & Compliance
• Certify S-glass composition (higher silica content) separately from E-glass to support value declarations
• Avoid pitfalls by including photos/micrographs of weave openness and filament cross-sections in entry docs
• Declare end-use as industrial to prevent consumer goods misclassification
