5510.20.00.00 - Other yarn, mixed mainly or solely with wool or fine animal hair (607) 🖩

This HTS category, 5510.20.00.00, specifically classifies yarn spun from man-made staple fibers that are mixed with wool or fine animal hair. The critical defining characteristic is that the blend must contain a predominant proportion of artificial staple fibers, with wool or fine animal hair constituting the remainder. These yarns are not intended for sewing thread and are not packaged for retail sale, indicating their use in further manufacturing processes within the textile industry.

To distinguish this category from its siblings, it is crucial to note the material composition. Unlike yarns predominantly of artificial staple fibers (5510.10), which would be classified elsewhere, this code is for blends where artificial staple fibers are the main component and wool or fine animal hair is present as a secondary component. It also differs from 5510.30, which covers yarns where cotton is the secondary component mixed with artificial staple fibers. Furthermore, the catch-all category 5510.90 encompasses other yarn types not specifically provided for elsewhere within the 5510 series.

As this is a leaf node within the HTS classification, there are no further subcategories. Therefore, classification under 5510.20.00.00 is definitive once the material composition and general yarn type have been established. Importers and exporters should carefully verify the weight percentage of artificial staple fibers relative to wool or fine animal hair to ensure accurate classification and compliance with customs regulations.
