9902.13.80 - Sleeping bag shells, unfilled, of woven taffeta fabric of polyester with thread count between 160 and 210 and formed from yarns between 22 and 112 decitex; such shells each weighing 25 g/m2 or more but not over 250 g/m2; measuring 152 cm to 305 cm in length, with zipper closure, valued not over $7 each (provided for in subheading 6307.90.98)

This HTS category, 9902.13.80, specifically covers unfilled sleeping bag shells. These shells are characterized by their construction from woven taffeta fabric of polyester, with a precise thread count ranging from 160 to 210 and yarns falling between 22 and 112 decitex. Further defining criteria include a weight per square meter of at least 25 grams but not exceeding 250 grams, and dimensions between 152 cm and 305 cm in length. A key feature for identification is the presence of a zipper closure. Crucially, these sleeping bag shells must be valued at no more than $7 each to fall under this provision, which acts as a temporary modification or special classification.

While the broader HTS database encompasses a vast array of goods from live animals (Chapters 01) to machinery and scientific equipment (Chapters 84-90), and even miscellaneous manufactured articles (Chapter 63), this specific heading operates within the "Temporary Legislation" chapter (Chapter 99). Therefore, its primary distinction from other categories is not based on the fundamental nature of the goods themselves, but rather on temporary trade policies, agreements, or restrictions applied to them. The parent context of Section XXII, "Special Classification Provisions," further emphasizes that this classification is not based on inherent product type alone, but on specific, often time-limited, regulatory considerations.

As a leaf node within its branch of the HTS, 9902.13.80 does not have subcategories. This means that all goods meeting the detailed description provided are classified directly under this code. The classification is therefore highly specific, relying on the precise physical and value-based criteria outlined to differentiate these sleeping bag shells from other textile articles or items that might otherwise appear related. The reference to "provided for in subheading 6307.90.98" indicates that this 9902 code acts as a temporary or specialized designation for goods that would ordinarily fall under the more general heading for other made-up textile articles.
