C-Glass Bulk Roving Fiber
Corrosion-resistant C-glass fibers in bulk form, used for chemical tank linings and marine applications. These fibers are at a pre-processing stage, not yet formed into yarn or woven goods, and are classified as 'other' glass fibres. The product meets the definition of glass under Chapter 70, including fused silica.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the fibers are twisted into rovings
Rovings are a specific form of glass fibre.
If the fibers are woven into fabric
Woven glass fibre products are classified separately.

AR-Glass Bulk Fibers
Alkali-resistant AR-glass fibers supplied in bulk form, used to reinforce concrete and for geotechnical applications. These fibers are unprocessed beyond initial manufacture, fitting the tariff item for 'other' glass fibres and articles thereof. They are not worked into yarn, rovings, or woven fabrics, and contain fused silica as permitted by Chapter 70 Note 5.
AR-Glass Chopped Strand Mat
Alkali-resistant AR-glass chopped strand mat for concrete reinforcement and GRC panels. High zirconia content provides durability in alkaline environments. Falls under tariff item 7019.90.00 as a non-woven glass fiber article not elsewhere specified.
AR-Glass Woven Fabric for Concrete Reinforcement
Alkali-resistant (AR) glass woven fabric used for reinforcing cement boards and shotcrete. The fabric's woven construction from AR-glass filaments provides high tensile strength and resistance to alkaline environments, making it essential for construction composites. It falls under tariff item 7019.90.00 as an article of glass fibers, specifically a woven fabric.
Basalt Fiber Continuous Roving
Continuous basalt fiber roving derived from melted basalt rock, used in high-temperature composites. Treated as glass fibers under Chapter 70 notes, which include fused silica-based fibers. Falls under tariff item 7019.90.00 as other glass fiber articles.
Basalt-Impregnated Glass Fiber Bulk
Hybrid glass fibers blended with basalt in bulk form, designed for fire-resistant composite applications. The predominant glass composition keeps this product within the scope of glass fibres, and the bulk form is not yet worked into yarn or fabric. This classification aligns with the tariff item for other glass fibre products.
Biaxial Woven Glass +/-45°
Biaxial woven glass fabric with fibers oriented at +/-45° for shear reinforcement in wind turbine blades. The stitched or woven construction from continuous glass filaments provides high shear strength and dimensional stability. This product is an article of glass fibers, specifically a woven fabric, under tariff item 7019.90.00.
