6704.90.00.00 - Of other materials

HTS Code 6704.90.00.00 encompasses articles of human hair, or of textile materials, that are not specifically enumerated in the preceding subheadings of heading 6704. This includes items like wigs, false beards, eyebrows, eyelashes, switches, and similar articles where the primary component is human hair or synthetic textile materials. The key characteristic of this classification is the exclusion of items made *exclusively* of animal hair or those falling under other more specific tariff provisions.

This category is distinct from its sibling, 6704.20.00.00, which specifically covers articles of human hair. While 6704.90.00.00 *can* include articles made of human hair, its primary scope lies in articles constructed from *other materials*, particularly synthetic textile materials, that serve similar functions to the hair-based articles described in other parts of the heading. The distinguishing factor is the absence of human hair as the sole or predominant constituent material when compared to the sibling category.

As this is a leaf node, there are no further subdivisions. Therefore, classification under 6704.90.00.00 hinges on the material composition. If an article, such as a wig or hairpiece, is not made of human hair and is not otherwise specifically classified, but is manufactured from materials like synthetic fibers (e.g., polyester, acrylic, nylon) or other textile materials, it would fall into this residual category, provided it meets the general description of heading 6704.
