6203.43.60.05 - Insulated, for cold weather protection (659)

This HTS classification, 6203.43.60.05, specifically covers bib and brace overalls designed for men or boys, constructed from synthetic fibers. The defining characteristic for this subcategory is their intended use for cold weather protection, indicated by their insulated nature. This means the garments will typically feature an insulating layer or filling to provide enhanced warmth in low-temperature environments.

While the parent category encompasses various types of trousers, bib and brace overalls, breeches, and shorts of synthetic fibers, this specific subcategory is distinguished by its "bib and brace" design, which includes a bib front and shoulder straps, as opposed to standard trousers or shorts. Furthermore, it is differentiated from other "Other" categories at the same level by the explicit requirement of being insulated for cold weather protection.

As this is a leaf node, there are no further subcategories. Therefore, classification within this code hinges on the precise determination that the garment is indeed a bib and brace overall made of synthetic fibers and possesses insulating properties for cold weather protection. Examples would include ski overalls or work overalls specifically designed with thermal insulation.
