6203.43.55.00 - Water resistant (659)

This HTS category, 6203.43.55.00, specifically classifies bib and brace overalls for men or boys that are made of synthetic fibers and are water-resistant. These garments are characterized by their trousers with an attached bib and suspenders, designed for workwear or protective purposes, and feature a water-repellent treatment. The "water-resistant" designation is a key distinguishing factor within this broader group of synthetic fiber bib and brace overalls.

Distinguishing this category from its sibling, 6203.43.60 ("Other"), is crucial for accurate classification. While the sibling category encompasses all other bib and brace overalls of synthetic fibers not meeting specific criteria, this particular classification requires the explicit characteristic of water resistance. This means garments that are solely made from synthetic fibers but do not possess water-repellent properties would fall under the "Other" sibling.

As a leaf node, this category does not have further subcategories. Therefore, the classification hinges entirely on the accurate identification of the garment as men's or boys' bib and brace overalls, composed of synthetic fibers, and possessing water-resistant properties. Classification relies on the specific treatment or construction of the fabric that imparts this water resistance.
