6204.63.60.05 - Insulated, for cold weather protection (659)

This HTS classification, specifically HTS 6204.63.60.05, pertains to bib and brace overalls designed for cold weather protection, constructed from synthetic fibers. These garments are characterized by their insulated nature, intended to provide significant thermal resistance against low temperatures. The inclusion of bib and brace features distinguishes them from other types of trousers or shorts, indicating a garment that covers the torso from the bib upwards, supported by straps. The "synthetic fibers" designation means the primary textile component must be man-made, such as polyester, nylon, or acrylic.

Given that this is a leaf node, there are no further subdivisions under this specific HTS code. Its distinction from sibling categories would lie in the combination of its specific construction (bib and brace), its intended purpose (cold weather protection with insulation), and its material composition (synthetic fibers). Any deviation in these key features, such as the absence of insulation, a different style of garment, or a composition primarily of natural fibers, would lead to classification under a different HTS code. For instance, non-insulated bib and brace overalls made of synthetic fibers would fall under a different subcategory.
