7019.73 - Other open fabrics:

This HTS category, 7019.73, encompasses "Other open fabrics" made from glass fibers, excluding veils and closed fabrics. These are textile materials produced from glass filaments where the weave construction creates visible openings or spaces between the yarns. The scope includes various forms of woven glass textiles that do not fit into more specific classifications within the "chemically bonded fabrics" designation, focusing on the open nature of their weave.

Distinction is crucial here. Unlike sibling category 7019.71.00.00, which specifically covers "Veils (thin sheets)," this category does not include such extremely thin and often non-woven constructions. Furthermore, it differentiates itself from sibling category 7019.72, which is dedicated to "Other closed fabrics." Therefore, 7019.73 is for glass fiber fabrics where the structure is discernibly open.

Within this category, two principal subcategories exist to further refine classification. Subcategory 7019.73.51.00 precisely identifies "Fiberglass tire cord woven from electrically nonconductive continuous fiberglass filaments 9 microns in diameter to 11 microns in diameter and impregnated with resorcinol formaldehyde latex treatment for adhesion to polymeric compounds (622)." This highly specific description targets a critical component in the automotive industry. The residual "Other" subcategory, 7019.73.90, is a residual classification for all other open glass fiber fabrics that do not meet the stringent criteria of the tire cord specification, ensuring comprehensive coverage for this product group.
