6206.40.20.00 - Containing 30 percent or more by weight of silk or silk waste (641)

This HTS classification pertains to women's or girls' blouses, shirts, and shirt-blouses that are not knitted or crocheted, and are specifically made from man-made fibers. The defining characteristic of this category is that the garment must contain 30 percent or more, by weight, of silk or silk waste. This detailed material composition is crucial for accurate classification, differentiating these garments from those with different fiber content.

To distinguish this category from its siblings, note that 6206.40.25 covers similar garments but is defined by a minimum of 36 percent by weight of wool or fine animal hair. The sibling category 6206.40.30, labeled "Other," would encompass women's or girls' blouses, shirts, and shirt-blouses of man-made fibers that do not meet the specific silk content threshold of this category, nor the wool or fine animal hair threshold of the other sibling. Therefore, the precise percentage of silk or silk waste by weight is the sole determinant for classification under 6206.40.20.00.

As this classification represents a leaf node within the HTS structure, there are no further subcategories. Consequently, classification under 6206.40.20.00 is final based on meeting the specified criteria of being a women's or girls' non-knitted/non-crocheted blouse, shirt, or shirt-blouse predominantly composed of man-made fibers, and containing 30 percent or more by weight of silk or silk waste.
