Products classified under HTS 7019.13.35.00
E-Glass Continuous Filament Yarn
E-glass yarn made from continuous filaments, used primarily in composite reinforcement for fiberglass products like boat hulls and automotive parts. Classified under HTS 7019.13.35.00 as 'other' yarn, slivers from glass fibers excluding glass wool. It meets Chapter 70 specifications for glass fibers processed into yarn form.
S-Glass Roving Yarn
High-strength S-glass roving yarn for aerospace composites and military applications, featuring low dielectric properties. Falls under HTS 7019.13.35.00 as 'other' glass fiber yarn or slivers. Distinguished from basic E-glass by superior tensile strength.
AR-Glass Yarn for Concrete Reinforcement
Alkali-resistant AR-glass yarn used in cement boards and GRC (glass fiber reinforced concrete) panels. HTS 7019.13.35.00 covers this 'other' glass fiber yarn designed for construction composites. Its zirconia content provides corrosion resistance in alkaline environments.
C-Glass Electrical Insulation Yarn
Corrosion-resistant C-glass yarn for electrical insulation in transformers and motors. Classified as 'other' yarn under HTS 7019.13.35.00 due to its borosilicate composition. Provides dielectric strength superior to E-glass.
Textile-Grade E-Glass Assembled Yarn
Multi-strand assembled E-glass yarn for woven industrial fabrics like filter cloths. HTS 7019.13.35.00 as 'other' slivers/yarn from continuous glass filaments. Features plied construction for weaving stability.
Direct Roving for Pultrusion
Untwisted direct roving E-glass yarn for pultrusion processes creating structural profiles. Under HTS 7019.13.35.00 as 'other' glass fiber roving/yarn. High strand count for resin impregnation in continuous molding.
Single-End Roving Yarn
Single-end roving from E-glass filaments for filament winding of pipes and tanks. HTS 7019.13.35.00 covers this 'other' sliver/roving form. Minimal twist preserves filament integrity for wet winding.
High-Silica Glass Yarn
High-silica (>80% SiO2) yarn for thermal protection in aerospace and furnace applications. Classifies under HTS 7019.13.35.00 as 'other' glass fiber yarn. Leached composition provides extreme heat resistance.
Basalt Fiber Yarn
Continuous filament yarn spun from molten basalt rock, used in construction and automotive composites. HTS 7019.13.35.00 includes this as 'other' glass-like fiber yarn per fused silica definition. Offers natural alkali resistance.
Polished Glass Fiber Yarn
Surface-polished E-glass yarn for optical fiber reinforcement and decorative composites. Under HTS 7019.13.35.00 as 'other' yarn; polishing per Chapter note doesn't affect pre-anneal classification. Smooth finish reduces resin demand.
