6204.29.40.40 - Containing 70 percent or more by weight of silk or silk waste (748)

This HTS category encompasses women's or girls' ensembles that are primarily constructed from textile materials other than those specifically enumerated in preceding subcategories. The term "ensembles" refers to coordinated sets of garments designed to be worn together. This classification applies to sets that do not fall under specific material classifications such as cotton, man-made fibers, or wool, and are not otherwise specifically provided for.

The distinction for this category lies in its residual nature, covering ensembles made from "other textile materials." It functions as a catch-all for coordinated outfits where the primary fabric is not explicitly detailed in more specific subheadings within the broader category of women's or girls' ensembles. Therefore, careful examination of the dominant fiber content is crucial to differentiate this category from those that specify materials like wool, cotton, or man-made fibers.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level, HTS Code 6204.29.40.40, is final. The defining characteristic for goods falling under this specific subheading is that they are women's or girls' ensembles composed of 70 percent or more by weight of silk or silk waste. This precise material composition, along with the garment type being an ensemble, dictates the final classification and associated duty rates.
