7019.69.90.21 - Weighing more than 215 grams per square meter, with a filament diameter of 7 to 13 microns (622)

This HTS category, 7019.69.90.21, specifically covers mechanically bonded fabrics made from glass fibers that are colored and weigh more than 215 grams per square meter, with a filament diameter ranging from 7 to 13 microns. These fabrics are characterized by their construction where glass fibers are physically entangled or bonded together, rather than being woven or knitted. The specified weight and filament diameter are key determinative factors for inclusion in this subcategory.

This classification is distinguished from its siblings by its specific weight and filament diameter criteria. Category 7019.69.90.10, for example, covers mechanically bonded colored glass fiber fabrics weighing 185 grams or less per square meter. Category 7019.69.90.60, on the other hand, is a broader "other" category for mechanically bonded colored glass fiber fabrics that do not meet the specific parameters of this or other subcategories. The "colored" aspect is common to these siblings, but the precise physical specifications delineate the distinctions.

As this is a leaf node within the HTS, there are no further subcategories under 7019.69.90.21. Therefore, classification within this code relies entirely on meeting the described physical attributes: being a mechanically bonded glass fiber fabric, being colored, weighing more than 215 grams per square meter, and possessing a filament diameter between 7 and 13 microns. This level of specificity ensures that products with these exact characteristics are consistently classified for customs purposes.
