5402.20.30 - Single yarn

This HTS category, 5402.20.30, specifically classifies single yarn made from high tenacity polyester filaments. These yarns are not intended for retail sale and are distinct from sewing thread. The "high tenacity" characteristic indicates yarns engineered for exceptional strength relative to their linear density, making them suitable for demanding applications.

The key distinction for this category lies in its single yarn construction. Its sibling, 5402.20.60, covers multiple (folded) or cabled polyester high tenacity yarns. Therefore, if a polyester high tenacity yarn is comprised of two or more single yarns twisted or combined together, it would fall under the sibling category.

Within this classification of single, high tenacity polyester yarn, further subdivision is made based on decitex, a measure of linear density. The subcategories are defined as "Not more than 920 decitex" and "More than 920 decitex." This distinction allows for more precise classification based on the thickness or weight of the yarn, which can be crucial for determining its end-use and associated duties.
