6203.42.45.21 - Imported as parts of playsuits (237)

This HTS category, 6203.42.45.21, specifically classifies boys' trousers and breeches made of corduroy, which are imported as parts of playsuits. The term "playsuits" in this context refers to coordinated garments designed for children's active wear or leisure. The corduroy material signifies a distinctive ribbed texture woven into the fabric, a key physical characteristic for classification.

Distinguishing this classification from its sibling, 6203.42.45.26 ("Other"), it is crucial to note that this node's specificity lies in the "playsuit parts" designation. While both fall under boys' corduroy trousers and breeches of cotton, this particular sub-heading isolates those intended for inclusion within a playsuit ensemble. This implies a potential functional relationship or a specific packaging/presentation that differentiates them from standalone boys' corduroy trousers and breeches.

As this is a leaf node, there are no further subcategories under 6203.42.45.21. Therefore, the classification is definitive for boys' corduroy trousers and breeches specifically designated as components of playsuits. Importers must ensure that the goods precisely match these criteria, considering both the material (corduroy), garment type (trousers/breeches), intended wearer (boys'), and their specific role as parts of a playsuit.
