6103.29.20.80 - Containing 70 percent or more by weight of silk or silk waste (759)

This HTS category, 6103.29.20.80, specifically classifies knitted or crocheted ensembles for men or boys where the primary textile material, comprising 70 percent or more by weight, is silk or silk waste. Ensembles, by definition, are sets of garments that are intended to be worn together, such as a suit jacket paired with matching trousers or a skirt. The inclusion of "silk or silk waste" is the defining characteristic for this particular subclassification within the broader category of men's or boys' ensembles of other textile materials.

This classification is distinguished from its sibling category, 6103.29.20.82, "Other," by the specific material composition. While the sibling category would encompass knitted or crocheted ensembles of other textile materials that do not meet the 70% silk or silk waste threshold, this category is exclusively for those that *do*. Therefore, the key differentiator is the preponderance of silk in the garment's composition.

As a leaf node within the HTS structure, this category does not have further subcategories. Classification at this level is finalized based on the fulfillment of the criteria outlined in the description, namely the garment type (ensemble), the method of construction (knitted or crocheted), the intended wearer (men or boys), and the significant weight percentage of silk or silk waste. Importers and exporters should meticulously verify the fiber content of their silk ensembles to ensure accurate classification and compliance.
