7019.64.15.10 - Weighing 185 grams or less per square meter (622)

This HTS category, 7019.64.15.10, specifically classifies mechanically bonded glass fiber fabrics that are closed woven and plain weave, made from coated or laminated yarns, and have a width not exceeding 30 cm. The defining characteristic of this subclassification is its specific weight: these fabrics must weigh 185 grams or less per square meter. This weight criterion is crucial for distinguishing these lighter-weight fabrics from other mechanically bonded glass fiber fabrics within the broader category.

Within the "Other" designation at this level, 7019.64.15.10 stands apart from its sibling category, 7019.64.15.90, which would encompass other mechanically bonded, closed woven, plain weave glass fiber fabrics of coated or laminated yarns with a width not exceeding 30 cm that *do not* meet the weight specification of 185 grams or less per square meter. Therefore, the primary differentiator between these two sibling nodes is the defined weight threshold for this specific classification. As this is a leaf node, there are no further subdivisions.
