6110.90.90.88 - Men's or boys' (838)

This HTS category, 6110.90.90.88, specifically classifies knitted or crocheted vests, waistcoats, and similar articles for men or boys, which are not made from cotton, synthetic fibers, or artificial fibers as detailed in preceding subheadings. The term "other textile materials" encompasses a broad range of fibers, including but not limited to wool, fine animal hair, silk, and vegetable fibers other than cotton. The "Other" subheadings at this level indicate that these garments do not fall into more specific classifications within the broader "of other textile materials" group.

The distinction from its sibling category, 6110.90.90.90, is solely based on the intended wearer. While this subheading covers garments for men or boys, the sibling subheading is reserved for identical types of garments designated for women or girls. Therefore, accurate classification hinges on identifying the gender for which the garment is designed, often discernible through sizing, cut, and styling.

As a leaf node, this classification represents the most specific level for this particular type of men's or boys' knitted or crocheted garment made from miscellaneous textile materials. Classification within this code requires confirming that the garment is indeed a vest, waistcoat, or a similar article of apparel, is knitted or crocheted, is not made from the explicitly excluded textile categories, and is intended for male wearers. Examples would include knitted wool vests for boys or crocheted silk waistcoats for men.
