6111.90.50.50 - Babiesʼ socks and booties (239)

This HTS category, 6111.90.50.50, specifically classifies babies' socks and booties that are knitted or crocheted and made from textile materials other than cotton or synthetic fibers, and are not of artificial fibers. This includes items crafted from materials such as silk, wool, animal hair, linen, or other vegetable fibers. The primary defining characteristic is their intended use for infants and their construction via knitting or crocheting.

It is crucial to distinguish this classification from its sibling categories. HTS 6111.90.50.30 covers babies' socks and booties of similar material composition but which are imported as part of a set. In contrast, 6111.90.50.70 encompasses other knitted or crocheted babies' socks and booties of other textile materials that do not fall under the specific criteria for this subcategory or the "parts of sets" sibling. Therefore, the key differentiator here lies in the specific material composition and whether the item is part of a set.

As this HTS code represents a leaf node in the tariff schedule, there are no further subcategories. Classification within this code is definitive once the criteria of being a knitted or crocheted baby sock or bootie, made from materials other than cotton, synthetic fibers, or artificial fibers, and not imported as part of a set, are met. Examples would include hand-knitted wool booties or crocheted silk socks for infants.
