7019.66.90 - Other

This HTS category, 7019.66.90, pertains to "Other" colored open-woven glass fiber fabrics. These fabrics are characterized by their plain weave construction, a weight not exceeding 250 g/m², and are made from filaments where each single yarn measures no more than 136 tex. The defining feature of this "Other" classification is that it captures colored mechanically bonded fabrics within the specified parameters that do not meet the precise specifications of sibling categories.

To distinguish this category, consider its sibling: 7019.66.70.00, which specifically covers fiberglass tire cord fabric woven from continuous fiberglass filaments within a defined diameter range (9 to 11 microns) and treated for adhesion to polymeric compounds. While both are open-woven glass fiber fabrics, 7019.66.90 is a broader residual category for other colored fabrics meeting the general criteria, lacking the specialized application and treatment of tire cord fabric.

The subcategories within 7019.66.90 further refine the classification based on specific physical properties. These include subdivisions based on the fabric's weight per square meter (e.g., weighing 185 grams or less per square meter, or weighing more than 215 grams per square meter) and, in some instances, the diameter of the constituent filaments. The residual subcategory, 7019.66.90.60, acts as a further catch-all for any colored open-woven glass fiber fabrics that meet the parent criteria but do not fit the more specific weight or filament diameter breakdowns.
