9902.12.37 - Doll diaper bags, with an outer surface of cotton textile material, each measuring not over 25 cm in width, 22 cm in height exclusive of handles and 10 cm in depth; such bags designed to hold and carry doll diapers and other doll-related accessories and having an attached flap designed to serve as a diaper changing mat for dolls (provided for in subheading 4202.92.15)

This HTS classification, 9902.12.37, specifically covers doll diaper bags that are designed to carry doll diapers and accessories. The key defining characteristics are the outer surface being of cotton textile material, and specific dimensions: not exceeding 25 cm in width, 22 cm in height (exclusive of handles), and 10 cm in depth. Furthermore, these bags must feature an attached flap intended to function as a changing mat for dolls. This provision is designated as being "provided for in subheading 4202.92.15," indicating a primary classification elsewhere, with this chapter 99 code offering a temporary modification or special provision.

Given that this is a leaf node within Chapter 99, there are no further subcategories to introduce. Instead, the focus remains on the precise criteria outlined in the description. It's important to note that while Chapter 99 encompasses temporary legislation and special provisions, this particular code is highly specific to the enumerated doll diaper bags. Therefore, comparisons with sibling categories, which are broad and varied, are less relevant for this specific entry than understanding the detailed requirements for a product to fall under this classification. The purpose, material, dimensions, and functional flap are all critical for correct identification.
