Uncolored Closed Woven Roving Glass Fabric for Wind Turbine Blades from China
This is a mechanically bonded, closed woven fabric made from uncolored glass fiber rovings, designed specifically for reinforcing wind turbine blade composites. It falls under HTS 7019.61.40 as it consists of closed woven rovings that are not colored and classified as 'other' non-lead crystal glass fiber fabrics. The tight weave provides strength and durability for high-stress structural applications.

Import Tips
• Verify the fabric is mechanically bonded and closed woven from rovings via lab testing to confirm HTS 7019.61.40 classification and avoid misclassification as open weave
• Provide mill certificates proving uncolored status and glass fiber composition exceeding 60% silica if resembling glass wool standards
