Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of carbon or graphite fibers
Heading 7019 excludes carbon/graphite; those use synthetic fiber codes like 6815.12, but glass stays in 70.
If coated or treated for technical textile use
If impregnated/coated for industrial textile functions, reclassifies to Chapter 59 textile articles.
If chopped strands rather than continuous fabric
Chopped glass strand mats fall under yarn/rovings in 7019.11 if not formed into bonded fabric.

Import Tips & Compliance
• Include technical data sheets proving S-glass composition and mechanical bonding to comply with fiber content verification
• Label shipments clearly as 'uncolored' to avoid customs challenges under colored subheadings
Related Products under HTS 7019.69.40
C-Glass Uncolored Spunlace Nonwoven Fabric
Corrosion-resistant C-glass fibers formed into uncolored nonwoven fabric via spunlace hydroentanglement mechanical bonding, used in filtration and insulation. HTS 7019.69.40 covers this as other not-colored mechanically bonded glass fiber fabrics. Pre-annealing processes do not alter classification per Chapter 70 notes.
E-Glass Mechanically Bonded Nonwoven Fabric
This is a nonwoven fabric made from E-glass fibers mechanically bonded without coloring, used primarily in composite reinforcement for automotive parts. It falls under HTS 7019.69.40 as 'other' mechanically bonded fabrics of glass fibers that are not colored. The mechanical bonding process, such as needle-punching, distinguishes it from chemically bonded or woven variants.
AR-Glass Mechanically Bonded Chopped Strand Mat
Alkali-resistant AR-glass chopped strand mat mechanically bonded without colorants, for concrete reinforcement in construction. Fits HTS 7019.69.40 as other uncolored mechanically bonded glass fiber fabrics. Glass includes fused silica variants per tariff definition.
Basalt-Glass Hybrid Nonwoven Bonded Fabric
Hybrid fabric blending basalt and glass fibers, mechanically bonded and uncolored, for high-temperature insulation applications. HTS 7019.69.40 applies as other glass fiber mechanically bonded fabrics. Mineral wool specs in notes confirm glass classification if SiO2 meets criteria.
