6203.19.10.30 - Waistcoats imported as parts of suits (359)

This HTS classification covers waistcoats that are specifically imported as integral components of men's or boys' suits. These waistcoats are designed to be worn with a suit jacket and trousers, forming a complete three-piece suit ensemble. They are manufactured from textile materials but are not knitted or crocheted, aligning with the broader scope of Chapter 62.

The key distinction for this category lies in its specific designation as a waistcoat intended as part of a suit, differentiating it from other suit components. While sibling categories at this level classify jackets (6203.19.10.10) and trousers, breeches, and shorts (6203.19.10.20) when imported as parts of suits, this code exclusively pertains to the waistcoat element. The material composition will be of "other textile materials" not specifically enumerated in preceding subheadings.

As this is a terminal classification (a leaf node), there are no further subcategories. Classification under 6203.19.10.30 relies on the item being a waistcoat and its clear intent and design to be part of a suit, as opposed to a standalone waistcoat or one intended for use with separate garments.
