Products classified under HTS 7019.12.00.80
E-Glass Roving for Wind Turbine Blades
E-glass roving consists of continuous untwisted strands of glass fibers bundled together, specifically designed for reinforcement in composite materials used in wind turbine blades. It falls under HTS 7019.12.0080 as 'other' rovings, not specified elsewhere in the subheading for slivers, rovings, yarn, and chopped strands. This product provides high tensile strength and corrosion resistance essential for large-scale renewable energy applications.
S-Glass Roving for Aerospace Composites
S-glass roving features high-strength continuous glass filaments for aerospace structural composites like aircraft fuselages. Classified in HTS 7019.12.0080 as other rovings, it meets Chapter 70 definitions for glass fibers including fused silica variants. Superior modulus and fatigue resistance distinguish it from standard E-glass.
AR-Glass Roving for Concrete Reinforcement
Alkali-resistant (AR) glass roving withstands cement's high pH environment, used in glass fiber reinforced concrete (GFRC) panels. HTS 7019.12.0080 covers this as other rovings meeting fused glass fiber definitions. Zirconia content provides essential chemical durability.
C-Glass Roving for Chemical Tank Linings
Corrosion-resistant C-glass roving for resin infusion in chemical storage tanks and piping. Falls under HTS 7019.12.0080 as other continuous filament rovings per Chapter 70 glass definitions. Borosilicate composition provides superior acid resistance.
Direct Roving 2400 Tex for Pultrusion
Direct-drawn E-glass roving at 2400 tex linear density for pultrusion processes making structural profiles. HTS 7019.12.0080 classification as other rovings not statistically specified. High strand count optimizes for continuous molding operations.
Single-End Roving for Filament Winding
Single-end glass roving for automated filament winding of pressure vessels and rocket motor casings. Classified HTS 7019.12.0080 as other rovings meeting continuous filament criteria. Controlled tension delivery system essential for hoop/winding patterns.
Textile Roving for Spray-Up Applications
Textile-sized glass roving optimized for robotic spray-up in open mold composites. HTS 7019.12.0080 covers as other rovings per Chapter 70 glass fiber definitions. Gun roving format prevents filament breakage during pneumatic chopping.
High-Strength ECR-Glass Roving
ECR (corrosion-resistant E-glass) roving for harsh marine/subterranean FRP applications. Falls under HTS 7019.12.0080 as other continuous rovings meeting fused glass criteria. Enhanced durability over standard E-glass.
