6203.43.70.20 - Boys' (447)

This classification specifically covers boys' trousers and breeches. These garments are part of the broader category of men's or boys' suits and trousers, falling under articles of apparel and clothing accessories made from textile materials, but not knitted or crocheted. The key defining characteristic of this subcategory is its intended user: boys.

This category is distinguished from its sibling, 6203.43.70.10, which covers men's trousers and breeches. The differentiation is based solely on the gender and age group for whom the apparel is designed. Both categories share the same material composition and construction type, but the intended wearer is the determining factor for classification.

As this is a leaf node in the HTS classification system, there are no further subcategories for boys' trousers and breeches. Therefore, the classification is definitive for these specific garments once the preceding criteria of being boys' trousers or breeches made of synthetic fibers, and not falling into more specific "Other" classifications, are met. Practical classification relies on accurate identification of the garment's intended use for boys.
