6110.30.10.30 - Men's or boys' (659)

This HTS classification, 6110.30.10.30, specifically covers knitted or crocheted vests for men or boys that contain 25 percent or more by weight of leather. These garments are designed as outerwear or layering pieces, distinct from the broader category of sweaters and pullovers. The defining characteristic for this sub-classification is the substantial leather content, which significantly influences the material composition and often the construction of the vest.

This category is distinguished from its sibling, 6110.30.10.40, by its intended wearer: this classification is exclusively for men's or boys' garments, whereas the sibling is for women's or girls' apparel. Both share the commonality of being knitted or crocheted vests with a significant leather component, but the gender specificity provides the key differentiator for proper classification.

As this is a leaf node, there are no further subcategories within 6110.30.10.30. Therefore, classification at this level is definitive based on the garment being a knitted or crocheted vest for men or boys containing at least 25% leather by weight. Practical considerations for classification would include confirming the knitted or crocheted construction and accurately calculating the leather content percentage by weight.
