Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in sliver form
Slivers are unprocessed fiber bundles classified separately from rovings in 7019.19.20.
If incorporated into finished concrete articles
Articles of cement with glass fiber reinforcement fall under 6809, not raw fibers.
If processed into other yarn types
Other woven or non-woven fabrics shift to 7019.59 if beyond basic roving form.

Import Tips & Compliance
• Document zirconia oxide percentage (>14%) to prove AR properties; comply with ASTM specs for construction use; pitfall: bulk packaging may trigger weight-based duties
