5509.61.00.00 - Mixed mainly or solely with wool or fine animal hair (607)

This HTS classification, 5509.61.00.00, pertains to yarns spun from synthetic staple fibers, specifically those which are either predominantly or exclusively blended with wool or fine animal hair. These yarns are not intended for direct sale to consumers in retail packaging. The core defining characteristic is the composition of the yarn, which must consist of man-made staple fibers as the primary component, intricately mixed with at least 60% wool or fine animal hair by weight.

The distinction between this category and its siblings lies in the accompanying fiber. Unlike sibling category 5509.62.00.00, which is for yarns mixed mainly or solely with cotton, or the broader category 5509.69 for other mixtures, 5509.61.00.00 is specifically for blends involving wool or fine animal hair. This focus ensures precise classification based on the non-synthetic fiber component of the blend.

As this is a leaf node in the HTS database, there are no further subcategories under 5509.61.00.00. Therefore, the classification is finalized at this level. Importers and exporters should ensure that the yarn in question meets the material composition criteria of being derived from synthetic staple fibers and being mixed mainly or solely with wool or fine animal hair to correctly apply this HTS code.
