7019.66.90.10 - Weighing 185 grams or less per square meter (622)

This HTS classification, 7019.66.90.10, specifically covers open woven glass fiber fabrics that are colored and have a weight of 185 grams or less per square meter. These fabrics are characterized by their construction, utilizing plain weave and filaments where each single yarn measures no more than 136 tex. The "Other" designation within this subcategory indicates that these fabrics do not fall under more specific weight or filament diameter parameters that might be defined in other sibling categories.

Distinguishing this category from its siblings, 7019.66.90.21 is reserved for colored open woven fabrics weighing *more than* 215 grams per square meter and possessing a filament diameter between 7 and 13 microns. The sibling 7019.66.90.60, also designated as "Other," would typically encompass colored open woven glass fiber fabrics that don't meet the specific weight criteria of 7019.66.90.10 or the detailed specifications of 7019.66.90.21. Therefore, 7019.66.90.10 acts as a distinct grouping for lighter-weight colored open woven glass fabrics within this specific plain weave structure.

As this is a leaf node in the HTS classification structure, there are no further subcategories. Classification at this level is determined by the specific weight threshold (185 grams or less per square meter) and its status as a colored, open woven glass fiber fabric with a plain weave using filaments within the specified tex range.
