6203.43.90.30 - Men's (647)

This HTS classification covers men's shorts specifically made from synthetic fibers, excluding those that are knitted or crocheted. These shorts are designed for adult males and fall under the broader category of trousers, bib and brace overalls, breeches, and shorts. The key characteristic for this classification is the material composition; the primary fibers used in the construction of the shorts must be synthetic.

This category is distinct from its sibling, "Boys'," which would encompass similar shorts made of synthetic fibers but intended for younger males. The classification hinges on the intended gender and age group of the wearer. Furthermore, it differentiates itself from other subcategories of shorts by its specific material requirement of synthetic fibers.

As a leaf node, this classification does not have further subcategories. Therefore, classification within this specific code relies on a precise determination that the garment is indeed shorts, made for men, and composed of synthetic fibers, adhering to the definition of "other" within the hierarchy, meaning it does not fit into any more specific sub-classifications for synthetic shorts.
