6203.29.30.70 - Containing 70 percent or more by weight of silk or silk waste (759)

This HTS classification, 6203.29.30.70, specifically covers men's or boys' ensembles made from textile materials other than cotton, wool, or man-made fibers, which contain 70 percent or more by weight of silk or silk waste. An ensemble, in this context, refers to a set of garments that are intended to be worn together, typically comprising a suit-type jacket or blazer with trousers, shorts, or breeches. The defining characteristic for this subcategory is the high silk content, distinguishing it from ensembles made of other textile blends.

This category is differentiated from its sibling, 6203.29.30.80, primarily by its specific material composition. While both fall under "Ensembles: Of other textile materials: Other: Other," this particular subcategory requires a predominant silk content of 70% or more by weight. The sibling category likely encompasses ensembles of other textile materials that do not meet this specific silk threshold.

As this is a leaf node, there are no further subcategories. Therefore, classification into this code hinges entirely on meeting the criteria of being a men's or boys' ensemble, composed of textile materials other than the primary categories, and possessing a silk or silk waste content of at least 70% by weight. Examples would include a tailored jacket and matching trousers crafted predominantly from silk fabrics.
