9902.12.80 - Woven fabrics of carded vicuna hair, containing 85 percent or more by weight of vicuna hair and of a weight exceeding 300 g/m2 (provided for in subheading 5111.19.60).

This HTS category, 9902.12.80, specifically addresses woven fabrics made from carded vicuna hair. The defining characteristics for classification within this provision are that the fabric must contain 85 percent or more by weight of vicuna hair and have a weight exceeding 300 grams per square meter. This narrow scope ensures that only very specific types of high-quality vicuna textile products are captured here, aligning with the temporary and specialized nature of Chapter 99.

As a node within Chapter 99, this classification falls under temporary legislation and special provisions, which often involve specific quantitative restrictions or duty modifications. Unlike the broader HTS categories found at higher levels which cover diverse product groups like live animals (e.g., 0101 for horses, 0102 for bovine animals), this provision is focused exclusively on a particular type of textile. The "provided for in subheading 5111.19.60" note indicates that the underlying classification for these fabrics, without these specific temporary provisions, would be elsewhere in the permanent HTS structure.

Given that 9902.12.80 is a leaf node, there are no subcategories to introduce. The classification ends at this specific product description. Therefore, understanding this category requires a thorough grasp of the vicuna hair content, weight per square meter, and the understanding that it operates under special trade agreement or agricultural adjustment act provisions, rather than a broad categorization of textile types.
