5402.49.11.00 - Colored multifilament, of modacrylic, untwisted or with a twist of less than 5 turns per meter, measuring not less than 22 decitex per filament, certified by the importer to be used in the manufacture of wigs for dolls

This HTS category specifically classifies multifilament yarns made from modacrylic fibers. These yarns are characterized by being colored, untwisted, or having a twist of less than 5 turns per meter. A critical defining factor is that each filament within the yarn must measure at least 22 decitex. Furthermore, for classification under this heading, the importer must certify that the yarn's intended use is solely for the manufacture of wigs for dolls.

This classification is distinguished from its sibling category, 5402.49.91, by the specific end-use requirement. While 5402.49.91 covers "Other" yarns within this general framework, this subcategory carves out a niche for modacrylic multifilament yarns with a precise filament decitex and a certified application in doll wig production, a restriction not present in the broader "Other" category.

As this is a leaf node in the HTS structure, there are no further subdivisions within this specific classification. The detailed description provided, including the material (modacrylic), construction (multifilament, twist level), filament decitex, and a specific end-use certification (doll wigs), fully defines the scope of goods that fall under HTS code 5402.49.11.00. Therefore, classification relies directly on meeting all these precise criteria.
