5402.11 - Of aramids:

This HTS category, 5402.11, specifically covers high tenacity yarn of aramids. Aramids are a class of synthetic fibers known for their exceptional strength-to-weight ratio, heat resistance, and resilience. This classification applies to such yarns, whether they are textured or not, and are not intended for retail sale. The emphasis is on the material composition (aramids) and the characteristic of high tenacity, indicating a yarn designed for demanding applications.

This category is distinguished from its sibling, 5402.19, which is designated for "Other" high tenacity yarns of nylon or other polyamides. Therefore, classification under 5402.11 is exclusively for aramid-based high tenacity yarns, while 5402.19 would encompass similar yarns made from different polyamide materials that do not fall into the aramid family. This distinction is crucial for accurate import and export declarations, ensuring compliance with specific duty rates and trade regulations associated with aramid fibers.

Within this classification, further subdivisions exist to refine the type of aramid yarn. Subcategory 5402.11.30 covers "Single yarn," referring to a yarn consisting of a single strand. Conversely, 5402.11.60.00 encompasses "Multiple (folded) or cabled" yarns, which are formed by twisting two or more single yarns together. This granular level of classification allows for precise identification based on the yarn's construction, impacting its suitability for various end-uses and potential for further processing.
