6201.90.19.00 - Containing 70 percent or more by weight of silk or silk waste (734)

This HTS category, 6201.90.19.00, specifically classifies men's or boys' overcoats, carcoats, capes, cloaks, anoraks (including ski jackets), windbreakers, and similar articles that are not knitted or crocheted, and are constructed of textile materials other than those falling under heading 6203. The defining characteristic for this particular subcategory is that these garments must contain 70 percent or more by weight of silk or silk waste. This material content is the primary differentiator for inclusion.

This classification is distinguished from its sibling category, 6201.90.29, which covers "Other" similar garments of textile materials not of silk. Therefore, if an overcoat or similar outerwear is made of synthetic fibers, cotton, wool, or a blend where silk is less than 70% by weight, it would not fall under 6201.90.19.00. The emphasis here is on the high silk content as the defining factor.

As this is a leaf node in the HTS classification structure, there are no further subcategories. Classification under 6201.90.19.00 is definitive for men's or boys' outerwear meeting the criteria of being made from materials other than those in 6203, specifically falling into the "other textile materials" category, and crucially, comprising at least 70% silk or silk waste by weight. Practical examples would include luxurious silk trench coats, silk lined windbreakers, or silk capes designed for warmth and style.
