5402.11.30.10 - Monofilament; multifilament, untwisted or with twist of less than 5 turns per meter

This HTS classification, 5402.11.30.10, specifically covers high tenacity single yarn made from aramids, which has a decitex not exceeding 920. These yarns are characterized by their monofilament construction or, if multifilament, have a twist of less than 5 turns per meter. The emphasis on "high tenacity" indicates yarns designed for exceptional strength and durability, crucial for applications requiring significant tensile strength.

The primary distinction of this category from its sibling, 5402.11.30.30, lies in the yarn's twist. While both are high tenacity aramid single yarns not exceeding 920 decitex, this classification is for those with minimal or no twist (under 5 turns per meter). The sibling category, conversely, covers yarns with a twist of 5 turns or more per meter. This difference in twist can affect yarn properties and end-use suitability, making it a key differentiator for customs purposes.

As this is a leaf node, there are no further subdivisions. Therefore, classification into this code is final based on the material (aramid), form (single yarn), tenacity (high), decitex (not more than 920), and twist (less than 5 turns per meter). Examples of typical uses for such yarns include reinforcement in technical textiles, industrial ropes, and specialized safety equipment where extreme strength-to-weight ratio is paramount.
