Blue Colored S-Glass Woven Fabric for Marine Composites from Germany
This plain weave, mechanically bonded fabric uses blue-colored S-glass fibers, kept non-coated for infusion molding in boat hulls and marine structures. It qualifies for HTS 7019.63.90.60 as 'other colored' closed woven glass fabrics without lamination. The high-strength S-glass provides superior tensile properties for saltwater environments.

Import Tips
• Submit tensile strength test reports confirming S-glass specs and mechanical bonding to avoid generic glass misclassification
• Declare colorfastness certifications, as marine exposure requires UV/stability docs for customs review
• Avoid pitfall of classifying pre-impregnated versions, which belong in 7019.40
