9902.13.46 - Women's or girls' knitted or crocheted vests of man-made fibers, containing 23 percent or more by weight of wool, each with fabric stitch count greater than 9/2 cm, measured in the direction the stitches are formed (provided for in subheading 6110.30.15)

This HTS category, 9902.13.46, specifically covers women's or girls' knitted or crocheted vests made from man-made fibers. A key defining characteristic is that these vests must contain a significant amount of wool, specifically 23 percent or more by weight. Furthermore, the fabric's construction is critical, requiring a stitch count greater than 9 stitches per centimeter, measured in the direction the stitches are formed. This detailed specification ensures precise identification of these particular garment types within the broader scope of chapter 61.

It is important to note that this is a temporary modification or special provision, indicated by its placement within Chapter 99. This means the classification is subject to specific, often fluctuating, trade policies or restrictions, as opposed to the permanent classification system found in earlier chapters of the HTS. While the underlying garment might otherwise fall under chapter 61, this 9900 series code imposes an additional layer of control or specific treatment for these particular wool-containing, man-made fiber vests.

As this is a leaf node, there are no further subcategories within 9902.13.46. Therefore, the focus for classification purposes remains on strictly adhering to the stipulated criteria: the garment's type (vest), gender (women's or girls'), construction method (knitted or crocheted), primary fiber content (man-made), minimum wool content (23% by weight), and the specific fabric stitch density requirement. Any deviation from these precise conditions would necessitate classification under a different HTS provision.
