7019.13 - Other yarn, slivers:

This category, HTS 7019.13, encompasses other types of yarn made from glass fibers, which are not specifically defined as chopped strands or rovings. Glass fiber yarn is characterized by its filamentous nature, produced through spinning or twisting fine glass filaments. This includes yarns formed for various textile applications or for reinforcement purposes, where the individual strands are aggregated and twisted to form a continuous thread. The key distinguishing factor is its form as a yarn, as opposed to the shorter, discrete lengths found in chopped strands or the untwisted bundles characteristic of rovings.

Distinguishing HTS 7019.13 from its siblings is crucial for accurate classification. Unlike HTS 7019.11.00.00, which specifically covers chopped strands of a length not exceeding 50 mm, this category deals with yarns in a spun or twisted form. It is also separate from HTS 7019.12.00, which classifies rovings, characterized by untwisted parallel filaments or strands. Furthermore, this category does not include mechanically bonded (7019.14.00.00) or chemically bonded (7019.15.00.00) mats, which are distinct forms of glass fiber material.

The subcategories within HTS 7019.13 further refine the classification of these "other" yarns. The presence of a "Yarns:" subdivision indicates that further distinctions may exist based on the specific type or construction of the yarn. The subsequent subdivision, 7019.13.35.00 "Other," suggests that this represents a residual category for glass fiber yarns that do not fall into any more specific sub-classifications within the "yarns" group. These subdivisions help in precisely identifying the nature of the glass fiber yarn for tariff purposes, considering factors such as denier, twist, or intended application.
