5606.00.00 - Gimped yarn, and strip and the like of heading 5404 or 5405, gimped (other than those of heading 5605 and gimped horsehair yarn); chenille yarn (including flock chenille yarn); loop wale-yarn

This HTS category, 5606.00.00, encompasses specialized yarns and strips that are characterized by their looped, twisted, or cut pile structure, often referred to as "gimped." This includes yarns or strips made from materials covered by headings 5404 or 5405 that have undergone a gimped treatment. Gimped yarn typically involves twisting threads around a core yarn or applying decorative elements to create a raised or textured effect. The category specifically excludes gimped items already classified under heading 5605 and gimped horsehair yarn, directing these to their respective headings. Chenille yarn, renowned for its soft, fuzzy texture achieved through a process of cutting loops to create a pile, is also a primary component of this classification. Additionally, loop wale-yarn, which features prominent loops forming a distinctive wale structure, falls under this heading.

When differentiating from sibling categories, it's important to note that while other headings within Section XI deal with various forms of yarn, thread, and cordage, 5606.00.00 focuses on specific decorative or structural finishes applied to these materials. For instance, it is distinct from basic spun yarns or twisted yarns where such gimped, chenille, or loop wale characteristics are not present. The emphasis here is on the manufacturing process and the resulting aesthetic and textural properties that differentiate these specialized yarns.

Within this classification, two subcategories are provided to further refine the classification of these gimped, chenille, and loop wale yarns and strips. The first subcategory, 5606.00.00.10, specifically addresses items that contain elastomeric filaments, recognizing the impact of elastic properties on the yarn's use and characteristics. The second subcategory, 5606.00.00.90, serves as a residual classification for all other yarns and strips that meet the general description of heading 5606.00.00 but do not contain elastomeric filaments. This differentiation allows for more precise tariff application based on material composition.
