7019.19.91.00 - Other

This HTS category, 7019.19.91.00, encompasses "Other" articles within the broader classification of glass fibers, including glass wool, and their manufactured products such as yarn, rovings, woven fabrics, chopped strands, and mats. Specifically, this subheading applies to slivers, rovings, yarn, and chopped strands and mats that do not meet the specific criteria outlined in other subheadings at this level. It serves as a residual category for glass fiber materials in these forms that are not otherwise specified.

To differentiate this category from its siblings, consider the specific parameters defined for other subheadings. For instance, 7019.19.30.00 is designated for chopped strands exceeding 50 mm in length, while 7019.19.70.00 is reserved for specialized fiberglass rubber reinforcing cord with precise filament diameter and treatment specifications. Therefore, 7019.19.91.00 would classify slivers, rovings, yarn, or chopped strands and mats that do not fall into these explicitly defined categories, such as chopped strands of shorter lengths or various types of glass fiber yarn and rovings not covered by other specific descriptions.

As this is a leaf node in the HTS structure, there are no further subcategories for this classification. Classification under 7019.19.91.00 relies on the exclusion of the goods from more specific sibling classifications. Importers and exporters should carefully examine the physical characteristics and specifications of their glass fiber materials in sliver, roving, yarn, chopped strand, or mat form to ensure they correctly apply this residual classification when no other distinct category is applicable.
