6206.20.20 - Containing 30 percent or more by weight of silk or silk waste

This HTS category, 6206.20.20, specifically classifies women's or girls' blouses, shirts, and shirt-blouses that are primarily composed of silk or silk waste, containing 30 percent or more by weight of these materials. This classification applies to garments that are not knitted or crocheted and fall within the broader scope of Section XI, covering textile and textile articles. The focus on silk content is a critical determinant for inclusion within this sub-heading.

Distinguishing this category from its sibling, 6206.20.30, relies on the material composition. While both fall under "Other" within the broader "Of wool or fine animal hair" parent category, 6206.20.20 is exclusively for silk-rich apparel, whereas 6206.20.30 would encompass other materials not otherwise specified. The parent category context indicates these garments are distinct from those made primarily of wool or fine animal hair, despite the hierarchical placement.

The subcategories, 6206.20.20.10 and 6206.20.20.20, further refine the classification by distinguishing between garments intended for women and those for girls. This differentiation is important for statistical tracking and potentially for specific trade regulations or duties applied based on the intended wearer. Both subcategories maintain the core requirement of the garment being a blouse, shirt, or shirt-blouse and containing 30 percent or more silk by weight.
