6110.30.30.15 - Boys' (645)

This HTS category, 6110.30.30.15, specifically classifies boys' sweaters, pullovers, sweatshirts, waistcoats (vests), and similar articles that are knitted or crocheted and made of man-made fibers. These garments fall under the broader "Other" subcategories within the knitted or crocheted man-made fiber apparel section, indicating they do not fit into more specific prior classifications. The "boys'" designation is a crucial differentiator for proper customs reporting.

This classification is distinguished from its siblings by the intended wearer. While 6110.30.30.10 covers men's articles, and 6110.30.30.20 and 6110.30.30.25 encompass women's and girls' items respectively, this particular code is exclusively for apparel designed for boys. All these sibling categories share the common characteristics of being knitted or crocheted, made from man-made fibers, and falling under the general "sweaters and similar articles" description.

As a leaf node, this classification has no further subcategories. Therefore, the focus for correct classification rests on accurately identifying the garment as a sweater or similar article, confirming it is knitted or crocheted from man-made fibers, and crucially, that it is specifically intended for boys. This includes a wide range of casual and more formal knitted tops designed for male children.
