6104.63.20.26 - Containing 5 percent or more by weight of elastomeric yarn or rubber thread (648)

This HTS classification, 6104.63.20.26, specifically pertains to knitted or crocheted trousers and breeches for girls that are of synthetic fibers and contain 5 percent or more by weight of elastomeric yarn or rubber thread. This detailed classification ensures the accurate categorization of girls' lower body garments made from synthetic materials exhibiting significant stretch properties. The presence of elastomeric yarn or rubber thread is a key distinguishing factor for this category, indicating garments designed for enhanced fit, comfort, or performance.

This particular sub-category, "Other," at this granular level distinguishes itself from its sibling, 6104.63.20.28, which is also designated as "Other." The critical differentiator lies within the defining characteristic of the 6104.63.20.26 code: the explicit inclusion of 5 percent or more by weight of elastomeric yarn or rubber thread. This means that while both might fall under a broader "Other" classification at a higher level, 6104.63.20.26 is for those trousers and breeches with specific stretch components, whereas the sibling category would encompass synthetic trousers and breeches for girls that do not meet this elastomeric content threshold.

As this classification represents a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, the classification is definitive for the described goods. The focus for importers and customs officials remains on accurately verifying the material composition, specifically the percentage of elastomeric yarn or rubber thread, in conjunction with the garment type (trousers and breeches) and intended wearer (girls), all within the context of knitted or crocheted articles of synthetic fibers.
