6114.30.20.10 - Of fabric containing by weight 5 percent or more elastomeric yarn or rubber thread (659)

This HTS classification covers bodysuits and bodyshirts that are knitted or crocheted and made from man-made fibers. These garments are designed to cover the torso and potentially the lower body, often worn as underwear, base layers, or as standalone fashion items. The defining characteristic is their construction from knitted or crocheted fabric composed of man-made fibers, distinguishing them from garments made from woven textiles.

This specific subheading is further refined by the presence of elastomeric yarn or rubber thread. Goods classified here must contain 5 percent or more of these materials by weight. This requirement allows for garments with enhanced stretch, comfort, and fit, commonly found in activewear or specialized undergarments. The inclusion of elastomeric content is a key differentiator from other man-made fiber bodysuits and bodyshirts that may not possess these elastic properties.

As this is a leaf node, there are no further subcategories within this specific HTS code. Classification at this level relies on the confirmation of the garment being a bodysuit or bodyshirt, its knitted or crocheted construction, its composition of man-made fibers, and the critical requirement of containing at least 5% elastomeric yarn or rubber thread by weight.
