7019.19 - Other:

This HTS classification, 7019.19, encompasses "Other" materials within the broader category of glass fibers and articles thereof, specifically focusing on slivers, rovings, yarn, and chopped strands. It serves as a residual category for items that do not fit into more specific subheadings under heading 7019.1, such as explicitly defined chopped strands of a specific length or rovings.

The primary distinction for 7019.19 lies in its exclusion of goods already classified under more precise sibling categories. For instance, while 7019.11.00.00 specifically covers chopped strands with lengths of 50 mm or less, and 7019.13.00.00 addresses other yarn and slivers, this heading captures those that fall outside these definitions. It also differentiates from mat categories like 7019.14.00.00 and 7019.15.00.00, which pertain to mechanically or chemically bonded mats.

Within 7019.19, further subdivisions exist to provide more granular classification. The subcategory 7019.19.30.00 specifically addresses chopped strands exceeding 50 mm in length, thereby separating them from the shorter strands classified elsewhere. Additionally, 7019.19.70.00 is designated for specialized fiberglass rubber reinforcing cord, highlighting its unique construction and intended application. The remaining items, not specifically defined by these subcategories, fall under the residual 7019.19.91.00, "Other."
