9902.12.81 - Woven fabrics of combed vicuna hair, such fabrics containing 85 percent or more by weight of vicuna hair, of a weight not exceeding 200 g/m2 (provided for in subheading 5112.11.60).

This HTS category, 9902.12.81, specifically addresses woven fabrics composed primarily of combed vicuna hair. To qualify for this classification, the fabric must contain 85 percent or more vicuna hair by weight and have a weight not exceeding 200 grams per square meter. These textiles are designated for special classification under temporary legislation, as indicated by their placement within Chapter 99.

While this category focuses on a very specific type of woven fabric, it is important to distinguish it from other categories within the HTS. Sibling categories at this level, such as those for live animals (e.g., horses, bovine, swine, sheep, goats, poultry), cover entirely different product types and are governed by different sets of rules and duties. Furthermore, even within textile classifications, this node's specificity regarding material (vicuna hair), weight, and weaving process sets it apart from broader categories of woven fabrics made from other animal or synthetic fibers, or those exceeding the specified weight limit.

As a leaf node within the HTS, HTS Code 9902.12.81 does not have further subdivisions. Therefore, classification under this code is definitive, provided the goods meet all the stipulated criteria. Importers must ensure that documentation accurately reflects the vicuna hair content, fabric weight, and weaving method to comply with customs regulations for these specialized textiles.
