5509.69 - Other:

This HTS classification, 5509.69, encompasses "other" yarns of synthetic staple fibers, specifically those made from acrylic or modacrylic fibers, which are not mixed predominantly or solely with wool, fine animal hair, cotton, or artificial staple fibers. These yarns are intended for industrial or manufacturing use and are not packaged for retail sale. The key characteristic distinguishing this category is the absence of significant blends with natural animal fibers, cotton, or man-made staple fibers originating from regenerated cellulose.

To further refine classification, this category is distinct from its siblings, 5509.61.00.00 (mixed mainly or solely with wool or fine animal hair) and 5509.62.00.00 (mixed mainly or solely with cotton). Goods falling under 5509.69 will therefore not contain a primary or sole admixture of these specific materials, allowing for a broader range of synthetic fiber compositions or mixtures with other synthetic staple fibers.

Within this broader classification, a further subdivision exists under 5509.69.60.00, which pertains to yarns that are mixed mainly or solely with artificial staple fibers. This highlights a critical distinction: while 5509.69 covers yarns where the primary synthetic fiber is acrylic or modacrylic and not mixed with wool, cotton, or artificial staple fibers, the subcategory specifically addresses those where the blend is primarily with artificial staple fibers. This granular level of detail ensures accurate classification based on the precise composition of the yarn.
