7019.62.90 - Other

This HTS category, "Other," under mechanically bonded fabrics of rovings and specifically within "Other closed fabrics of rovings," encompasses glass fiber fabrics that do not fit into more specific subheadings. It generally refers to a broad range of glass fiber fabrics formed through mechanical bonding processes, intended for applications beyond those explicitly detailed elsewhere. The key characteristic is the use of rovings, which are untwisted bundles of continuous glass filaments, that are then mechanically fastened together to create the fabric structure.

This classification is distinguished from its sibling category, 7019.62.70.00, which specifically covers fiberglass tire cord fabric. That sibling is defined by its precise filament diameter range and a particular impregnation treatment designed for adhesion to polymeric compounds, indicating a specialized application. In contrast, this "Other" category is for mechanically bonded fabrics of rovings that do not meet these specific criteria, suggesting a wider variety of constructions and intended uses.

The subcategories within this "Other" classification serve to further refine the scope. 7019.62.90.30 addresses silica filament fabric, highlighting a specific material composition with a high silica content as a defining characteristic. The remaining subcategory, 7019.62.90.60, acts as a residual provision for all other mechanically bonded fabrics of rovings that are closed fabrics, colored, and do not fall into the silica filament fabric designation. This structure allows for the accurate classification of diverse glass fiber fabric products.
