6103.49.20.00 - Bib and brace overalls (659)

This classification pertains to bib and brace overalls specifically designed for men and boys, which are knitted or crocheted and made from textile materials other than wool, fine animal hair, cotton, or man-made staple fibers. The defining characteristic of these garments is the presence of bib and brace attachments, distinguishing them from standard trousers.

While the immediate sibling category, 6103.49.10, covers other types of trousers, breeches, and shorts, this specific classification is reserved exclusively for bib and brace overalls. The materials composition is further refined to be of "other textile materials," implying fibers not explicitly listed in preceding subheadings within the men's or boys' knitted or crocheted apparel chapter. The further refinement of "Of artificial fibers" indicates these overalls are constructed from artificial textile materials.

As a leaf node, this classification does not have further subcategories. Therefore, the focus for classification within 6103.49.20.00 is on the definitive presence of the bib and brace feature, the knitted or crocheted construction, and the use of artificial fibers as the primary textile component. This ensures accurate segregation of these specialized garments from other forms of men's or boys' legwear.
