6104.63.10.30 - Girls' (659)

This HTS classification, 6104.63.10.30, specifically designates bib and brace overalls for girls that are knitted or crocheted and made of synthetic fibers. These garments are characterized by their shoulder straps that connect to a bib front, typically extending to full trousers or shorts. The "girls'" designation signifies that the sizing and design are intended for female children.

Within the "Of synthetic fibers" category for trousers, bib and brace overalls, and shorts, this code is distinguished from its sibling category, 6104.63.10.20, which covers identical garments but for "Women's" instead of "Girls'". The primary differentiator is the intended recipient, influencing the cut, style, and sizing of the garment.

As this is a leaf node in the HTS structure, there are no further subcategories under 6104.63.10.30. Therefore, classification at this level is definitive for girls' bib and brace overalls knitted or crocheted from synthetic fibers that do not fall under any more specific subheading. Practical considerations for classification would include verifying the fiber content and confirming the garment's construction as a bib and brace overall.
