6204.63.90.35 - Imported as parts of playsuits (237)

This HTS classification, 6204.63.90.35, specifically covers girls' shorts made of synthetic fibers that do not fall into any more specific subcategories. These shorts are distinct from "Other" categories at this granular level due to their explicit designation as "Shorts" and for "Girls'". The defining characteristic is that they are designed as parts of playsuits, indicating a functional relationship and intended assembly with other garments to form a complete playsuit ensemble.

While sibling categories might exist at the 6204.63.90 level for "Other" types of garments or shorts made from synthetic fibers, this particular code is reserved for those shorts intended as components of playsuits. The absence of further subcategories signifies that this is a terminal classification for this specific type of girls' shorts, meaning no further breakdown by material composition, specific style, or decorative features is provided at this level of the tariff.

For classification purposes, the primary determinant for this category is the garment's construction as shorts, its intended wearer (girls'), its material composition (synthetic fibers), and its specific functional role as a part of a playsuit. Importers must ensure that these shorts are indeed designated for use in playsuits, differentiating them from standalone shorts or shorts intended for other types of apparel.
