7019.66.40 - Other

This HTS category, 7019.66.40, encompasses "Other" mechanically bonded open-woven fiberglass fabrics that are not colored, have a width exceeding 30 cm, and are woven from filaments where each single yarn measures no more than 136 tex. The "Other" designation indicates this is a residual category for fabrics that meet the broader criteria of plain weave, weighing less than 250 g/m², not colored, but do not fit into more specific sub-classifications within this group.

It is crucial to distinguish this category from its sibling, 7019.66.30.00. The sibling specifically identifies fiberglass tire cord fabric, which is woven from electrically nonconductive continuous fiberglass filaments of a specific diameter range (9-11 microns) and treated for adhesion to polymeric compounds. In contrast, 7019.66.40 applies to a broader range of unenumerated, uncolored, mechanically bonded open-woven fiberglass fabrics that do not meet the specialized criteria of tire cord fabric.

The subcategories under 7019.66.40 further refine the classification based on the weight per square meter and, in one instance, filament diameter. Subcategory 7019.66.40.10 is for fabrics weighing 185 grams or less per square meter, while 7019.66.40.21 pertains to fabrics weighing more than 215 grams per square meter with a specific filament diameter range of 7 to 13 microns. The residual subcategory, 7019.66.40.96, captures any remaining uncolored, mechanically bonded open-woven fiberglass fabrics that do not fit into these more narrowly defined weight or diameter specifications.
