S-Glass Roving for Aerospace Composites from Mexico
S-glass rovings are continuous glass fibre bundles with higher tensile strength than E-glass, designed for aerospace structural composites such as aircraft skins and rocket casings. They are untwisted and lightly sized, meeting the definition of rovings. Their advanced performance characteristics do not affect their classification.

Import Tips
• Classify as rovings under 7019.12.00, not as yarn or fabric
• Provide certification of S-glass composition for CBSA verification
• Check if the roving is subject to export controls due to aerospace applications
