6203.43.09.20 - Boys' (447)

This HTS classification, 6203.43.09.20, specifically covers boys' trousers and breeches that are of synthetic fibers, fall under the category of recreational performance outerwear, and are classified as "Other" within that subcategory, and further "Other" within its subsequent grouping. The defining characteristic is that these garments must contain 36 percent or more by weight of wool or fine animal hair, despite being primarily constructed of synthetic fibers. This specific combination of material composition and intended use for active pursuits is key to its distinct placement.

This category is distinguished from its sibling, 6203.43.09.10, which covers "Men's" trousers and breeches meeting the same material and functional criteria. The distinction lies solely in the intended wearer and sizing, with 6203.43.09.20 exclusively applying to boys' garments. As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification is complete at this level, meaning goods fitting all preceding criteria will be classified here.
