6104.13.10.00 - Containing 23 percent or more by weight of wool or fine animal hair (444)

This HTS category, 6104.13.10.00, specifically classifies women's or girls' suits, knitted or crocheted, that are predominantly composed of synthetic fibers and contain 23 percent or more by weight of wool or fine animal hair. This distinction is crucial as it indicates a blend where synthetic fibers form the primary component, but a significant proportion of natural wool or fine animal hair is also present. These garments are designed as coordinated sets intended for wear as suits.

This classification distinguishes itself from its sibling category, 6104.13.20.00, which covers "Other" suits of synthetic fibers. The sibling category would encompass suits made from synthetic fibers that do not meet the 23 percent threshold for wool or fine animal hair content, or those suits where the composition is not clearly defined by the wool/fine animal hair percentage specified here. Therefore, the key differentiator for this code lies in the specific material composition requirement.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level is determined by the explicit criteria outlined: the garment type (suit), the method of construction (knitted or crocheted), the intended user (women or girls), the primary fiber content (synthetic fibers), and the specific threshold of wool or fine animal hair by weight.
