6106.20.10 - Containing 23 percent or more by weight of wool or fine animal hair

This HTS category, 6106.20.10, specifically classifies women's or girls' blouses and shirts that are knitted or crocheted and are primarily composed of man-made fibers. The defining characteristic for inclusion in this subcategory is that the textile component must contain 23 percent or more by weight of wool or fine animal hair. This means that while man-made fibers form the base of the fabric, a significant proportion of wool or fine animal hair (such as cashmere or mohair) must also be present.

Within the broader category of "Of man-made fibers" for knitted or crocheted blouses and shirts, this subcategory is distinct from its sibling, 6106.20.20, which covers "Other" man-made fiber blouses and shirts. The "Other" category would encompass items that do not meet the 23% by weight threshold for wool or fine animal hair, or are composed entirely of man-made fibers without any qualifying wool or fine animal hair content.

The subcategories within 6106.20.10 further differentiate based on the intended wearer. 6106.20.10.10 applies to women's blouses and shirts, while 6106.20.10.20 is for girls' blouses and shirts. This distinction allows for more precise customs declarations and statistical tracking, recognizing potential differences in sizing, design, or other factors that may be relevant for trade purposes.
