6209.20.50.45 - Imported as parts of sets (239)

This classification covers articles of apparel and clothing accessories for infants and children up to 36 months of age, specifically those made of cotton, which are imported as part of a set. The defining characteristic is that these garments are presented for retail sale as a collection of two or more items, where each item is designed to be worn together. Examples could include a coordinated set of a onesie, pants, and a hat, or a romper and matching bib, all composed primarily of cotton.

This category is distinguished from its sibling, 6209.20.50.50 ("Other"), by the specific condition of being imported as parts of sets. While both fall under the broader "Other" subcategories for cotton baby garments and accessories not knitted or crocheted, 6209.20.50.45 specifically targets those presented as a coordinated ensemble for sale, as opposed to individual pieces of cotton baby apparel or accessories. The "Other" sibling would encompass individual cotton baby garments or accessories not part of a pre-defined set.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification decision hinges on the precise definition of "parts of sets" as per customs regulations and interpretive notes. This requires careful consideration of whether the items are indeed presented together for retail sale and are intended to be coordinated in use, fulfilling the criteria for a "set" rather than simply a collection of unrelated items.
