7019.61.40.60 - Other (622)

This classification, "Other (622)" within HTS Code 7019.61.40.60, encompasses mechanically bonded fabrics of glass fibers that are of a closed woven construction made from rovings, are not colored, and do not fall into the specific subcategory for silica filament fabric. These are essentially woven glass fiber fabrics formed through mechanical bonding processes, where the filaments are held together without chemical binders, and the weave structure is closed. The "Other" designation signifies that this category serves as a residual grouping for fabrics that meet the broader criteria of mechanically bonded, closed-woven rovings but are not otherwise specifically enumerated.

Distinguishing this category from its sibling, 7019.61.40.30, is crucial. The sibling category is specifically designated for "Silica filament fabric of filaments with silica content greater than 93 percent." Therefore, this current "Other" category would cover mechanically bonded, closed-woven roving fabrics of glass fibers where the silica content is below 93 percent, or if the silica content is high but the fabric is not specifically defined as a "silica filament fabric" according to the criteria implied by the sibling.

As this is a leaf node in the HTS classification structure, there are no further subcategories to introduce. The classification is finalized at this level, based on the specific characteristics of the woven glass fiber fabric, including its method of bonding, construction type (closed woven rovings), color, and material composition (specifically, the absence of being a high-silica filament fabric). The "(622)" likely serves as an internal reference or indicator for customs authorities.
