7019.62.40 - Other

This category encompasses mechanically bonded fabrics made from glass fibers, specifically those classified as other closed fabrics of rovings. These fabrics are characterized by their construction where the rovings are bonded together by mechanical means, such as needle-punching, to form a non-woven textile. The material is primarily composed of glass filaments, and the "closed fabrics" designation implies a relatively dense construction.

Distinguishing this category from its sibling, 7019.62.30.00, is crucial. The sibling specifically covers fiberglass tire cord fabric, defined by precise filament diameter ranges and a specific resorcinol formaldehyde latex impregnation for adhesion to polymeric compounds, indicating a specialized application in tire reinforcement. In contrast, the current "Other" classification covers mechanically bonded fabrics that do not meet these specific tire cord fabric criteria.

The subcategories within 7019.62.40 provide further refinement. 7019.62.40.30 is designated for silica filament fabric, which requires a high silica content (greater than 93 percent), indicating a specialized material with enhanced heat resistance or other specific properties. The residual 7019.62.40.60 "Other" category serves as a residual for mechanically bonded, closed fabrics of rovings that do not qualify for the silica filament fabric designation.
