5509.53.00.60 - Exceeding 52 nm (607) 🖩

This HTS category, 5509.53.00.60, specifically covers yarns composed of polyester staple fibers that are mixed primarily or solely with cotton. These yarns are not intended for retail sale and are generally used in the manufacturing of textiles. The defining characteristic of yarns within this subcategory is their construction, which centers on the combination of synthetic polyester staple fibers with natural cotton fibers.

The crucial distinction for this classification lies in the filament length of the polyester staple fibers. Yarns classified under 5509.53.00.60 are characterized by polyester staple fibers that *exceed* 52 nanometers (nm) in length. This contrasts with its sibling category, 5509.53.00.30, which encompasses similar polyester/cotton blends but utilizes polyester staple fibers *not exceeding* 52 nm. This difference in staple fiber length is a key factor for accurate customs classification, influencing the physical properties and intended end-uses of the resulting yarns.

As this is a leaf node within the HTS structure, there are no further subdivisions. Therefore, classification into this specific code relies solely on the material composition (polyester staple fibers mixed mainly or solely with cotton) and the defining characteristic of the polyester staple fiber length (exceeding 52 nm). Importers and exporters should carefully verify the specification of the polyester staple fibers used in the yarn to ensure correct classification.
