6201.90.59.00 - Containing 70 percent or more by weight of silk or silk waste (735)

This HTS category, 6201.90.59.00, specifically classifies other outerwear for men and boys, falling under the broader definition of anoraks, windbreakers, and similar articles, that are not categorized under heading 6203. The defining characteristic of this subcategory is that the garments must contain 70 percent or more by weight of silk or silk waste. This material composition is the primary determinant for classification within this specific HTS code, ensuring that articles primarily fashioned from silk are accurately identified for customs purposes.

Distinguishing this category from its sibling, 6201.90.69 (Other), is crucial. While both fall under "Other" within the broader classification of anoraks and similar articles, this subcategory is exclusively for those predominantly made of silk or silk waste. The sibling category would encompass similar outerwear not meeting the 70% silk content requirement, potentially made from other textile materials like cotton, synthetic fibers, or wool blends not falling into more specific subdivisions.

As a leaf node, 6201.90.59.00 does not have further subcategories. Therefore, classification into this code hinges directly on the aforementioned criteria: the garment being a men's or boys' anorak, windbreaker, or similar article (excluding those of 6203) and containing at least 70% silk or silk waste by weight. Examples would include men's silk parkas, silk-rich ski jackets, or silk blended windbreakers that meet the weight threshold for silk content.
