6104.62.20.16 - Containing 5 percent or more by weight of elastomeric yarn or rubber thread (237)

This HTS category, 6104.62.20.16, specifically classifies knitted or crocheted trousers and breeches for girls that are imported as parts of playsuits, provided they contain 5 percent or more by weight of elastomeric yarn or rubber thread. The key defining features are the garment type (trousers and breeches), intended user (girls'), method of construction (knitted or crocheted), their status as components of playsuits, and the significant presence of elastic yarn or rubber thread.

This classification is distinct from its sibling category, 6104.62.20.21, which covers "Other" trousers and breeches for girls that do not meet the specific criteria for being imported as parts of playsuits or do not contain the specified percentage of elastomeric yarn or rubber thread. Therefore, the presence of playsuit context and the material composition are the critical differentiators for this subcategory.

As this is a leaf node, there are no further subcategories. The classification concludes at this level, meaning that any trousers and breeches for girls that are knitted or crocheted, imported as parts of playsuits, and contain 5 percent or more by weight of elastomeric yarn or rubber thread will be classified under this specific HTS code. This ensures precise tariff application based on the garment's function within a larger apparel set and its elastic material content.
