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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If slag wool with <60% SiO2
Chapter note excludes non-qualifying mineral wools from 7019, placing in 6806.
If chemically bonded instead of mechanical
Chemical bonding (e.g., resin) uses 7019.51/52 subheadings, distinct process.
If predominantly non-glass synthetic fibers
If glass <50%, reclassifies to Chapter 56 nonwovens of other textile materials.

Import Tips & Compliance
• Provide fiber composition breakdown (% glass vs. basalt) to affirm predominant glass fiber status
• Use moisture-proof packaging for hygroscopic fibers to prevent import rejection for contamination

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.
S-Glass Needle-Punched Nonwoven Mat
A high-strength S-glass fiber mat created through needle-punching for mechanical bonding, uncolored, ideal for aerospace composite layups. Classified in HTS 7019.69.40 as other non-colored mechanically bonded glass fiber fabrics. It retains heading 7019 character per chapter notes regardless of article-like form.
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.
