7019.61.90 - Other

This HTS category, 7019.61.90, encompasses "Other" colored, mechanically bonded, closed woven fabrics of glass fiber rovings. These are distinct from the specifically enumerated fiberglass tire cord fabric found under sibling code 7019.61.70.00, which details precise filament diameters and impregnation treatments for specialized adhesion purposes in tire construction. The scope here is broader, covering other colored woven fabrics made from glass fiber rovings that do not meet the specific criteria of the tire cord fabric.

The classification under 7019.61.90 is designed to capture colored woven fabrics of glass fiber rovings where the specific technical or application-based distinctions of the sibling category are not present. The "colored" aspect is a key differentiator, indicating that dyes or pigments have been incorporated into the fibers or fabric to impart a specific hue, distinguishing it from plain or naturally colored glass fiber fabrics.

Within this category, further subdivisions exist to refine the classification based on material composition and specific product types. Subcategory 7019.61.90.30 addresses silica filament fabric, requiring a silica content exceeding 93 percent, highlighting specialized high-silica applications. The remaining "Other" subcategory, 7019.61.90.60, serves as a residual category for any colored, mechanically bonded, closed woven fabrics of glass fiber rovings that do not fall into the high-silica filament classification.
