Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If weight 250 g/m² or more
Heavier fabrics exceed the <250 g/m² limit and classify under 7019.66.10.
If coated with plastics for textile reinforcement
Plastic-coated glass fabrics become textile-covered under Chapter 59.
If chemically bonded rather than mechanically
Chemical bonding (e.g., resins) uses different subheading 7019.61.

Import Tips & Compliance
• Submit fiber type certification (S-Glass composition) and weaving specs to CBP for accurate duty assessment
• Avoid common error of declaring weight inaccurately; use calibrated scales for g/m² verification
• Document import as individual fabric rolls, not prepregs, to prevent shift to composite headings
