6203.43.90.15 - Imported as parts of playsuits (237)

This HTS category, 6203.43.90.15, specifically classifies trousers and breeches for boys that are made of synthetic fibers. These items fall under the broader heading of men's or boys' suits and similar garments, and more narrowly, under trousers, bib and brace overalls, breeches, and shorts. The "Of synthetic fibers" designation signifies that the primary textile material comprising these garments is man-made, such as polyester, nylon, or acrylic.

The "Other" subdivisions at this level indicate that these specific trousers and breeches are not otherwise specifically enumerated in preceding subheadings. It is crucial to distinguish this category from its sibling, 6203.43.90.20, which also falls under "Other" trousers and breeches of synthetic fibers. While both are "Other," the distinction often lies in subtle variations in construction, design, or intended end-use that are not captured by more general descriptions, or potentially, a higher level of detail captured by the parent description "Imported as parts of playsuits (237)".

As this is a leaf node, there are no further subcategories under 6203.43.90.15. Therefore, classification within this code is definitive for boys' trousers and breeches composed of synthetic fibers that do not meet the criteria for any more specific subheading. The defining characteristic remains the combination of garment type (trousers/breeches), target demographic (boys'), material (synthetic fibers), and the specific context of being imported as parts of playsuits.
