5509.52.00.00 - Mixed mainly or solely with wool or fine animal hair (607) 🖩

This HTS category, 5509.52.00.00, classifies yarns, not intended for retail sale, composed primarily of polyester staple fibers. The defining characteristic of this classification is that these polyester staple fiber yarns are mixed mainly or solely with wool or fine animal hair. This includes yarns where wool or fine animal hair constitutes the predominant fiber by weight, or where it is the sole other fiber present alongside the polyester staple fibers.

This category is distinguished from its siblings by the specific co-mingled fiber. For instance, 5509.51 covers similar polyester staple fiber yarns mixed mainly or solely with artificial staple fibers. Alternatively, 5509.53.00 deals with polyester staple fiber yarns mixed mainly or solely with cotton. The "Other" category, 5509.59.00.00, would encompass polyester staple fiber yarns mixed with other fibers not specifically enumerated in the preceding subheadings.

As 5509.52.00.00 is a leaf node within the HTS, it has no further subcategories. Therefore, classification within this code depends directly on the accurate identification of the constituent fibers, specifically the presence of wool or fine animal hair in combination with polyester staple fibers, and the proportion of these fibers by weight. This yarn is typically used in the manufacturing of fabrics for apparel, upholstery, or other textile articles, but its presentation here is not for direct consumer purchase.
