6115.21.00 - Of synthetic fibers, measuring per single yarn less than 67 decitex

This HTS category encompasses panty hose and tights crafted from synthetic fibers, specifically those where each individual yarn measures less than 67 decitex. This decitex measurement is a crucial determinant, indicating a finer yarn construction. These items are designed for wear on the lower body, offering coverage from the waist or hips down to the feet, and are knitted or crocheted.

It is important to distinguish this classification from its sibling category, HTS 6115.22.00.00, which covers panty hose and tights of synthetic fibers made with yarns measuring 67 decitex or more. The fundamental difference lies in the fineness of the yarn used; this category specifically addresses the lighter, more delicate constructions. Another sibling, 6115.29, pertains to items made of textile materials other than synthetic fibers.

Within this category, further subdivisions exist to provide more granular classification. Subcategory 6115.21.00.10 specifically covers "Tights," distinguishing them from other types of panty hose. Subcategory 6115.21.00.20, labeled "Other," would capture any remaining panty hose and tights within this synthetic fiber and fine yarn criterion that do not fall under the specific "Tights" designation.
