7019.63.90 - Other

This HTS classification, 7019.63.90, pertains to "Other" mechanically bonded, closed woven glass fiber fabrics that are not coated or laminated and are colored. It falls under the broader category of glass fibers and articles thereof, specifically addressing woven fabrics. The "Other" designation indicates that this subcategory captures colored woven glass fiber fabrics that do not meet the specific criteria of other, more narrowly defined classifications at this level.

Distinguishing this category from its sibling, 7019.63.70, is crucial. The sibling specifically covers fiberglass tire cord fabric characterized by its filament diameter and specialized impregnation treatment for adhesion to polymeric compounds. In contrast, 7019.63.90 encompasses a wider array of colored, closed woven glass fiber fabrics that do not possess these specific tire cord fabric attributes. The emphasis here is on the fabric construction, material (glass fiber), its woven nature, the fact that it is colored, and the absence of coatings or laminations, without the specialized performance requirements of tire cord fabric.

Within this "Other" colored woven fabric category, there are further subdivisions to facilitate precise classification. The subcategories are 7019.63.90.30, which covers silica filament fabric with a high silica content (greater than 93 percent), and 7019.63.90.60, which serves as a residual category for all other colored woven glass fiber fabrics not classified as high-silica filament fabric. These subcategories allow for the distinction between fabrics with specific high-silica properties and other, general-purpose colored woven glass fiber materials.
