7019.64.40 - Other

This classification covers mechanically bonded fabrics made from glass fibers, specifically those that are closed woven and have a plain weave structure. These fabrics are manufactured from yarns and have undergone coating or lamination processes. The "Other" designation at this level indicates that these fabrics do not fit into more specific sub-classifications based on color.

Distinguishing this category from its sibling, 7019.64.30, is crucial. The sibling specifically details fiberglass tire cord fabric with precise filament diameters and a particular impregnation treatment for adhesion to polymeric compounds. This current "Other" category is for mechanically bonded, closed woven glass fiber fabrics that are not colored and do not meet the specific criteria of the tire cord fabric, offering a broader scope for uncolored, woven, and treated glass fiber fabrics.

Within this "Other" category, further distinctions are made through subcategories. One subcategory is for silica filament fabric where the filaments possess a silica content exceeding 93 percent, highlighting a specific material composition. The second subcategory, also designated "Other," serves as a residual classification for any remaining uncolored, mechanically bonded, closed woven glass fiber fabrics that do not meet the criteria for the silica filament fabric.
