9902.12.38 - Sleeping bag carrying bags (“stuff sacks”), of woven taffeta fabric of polyester with 160 or more but not over 210 thread count, formed from 22 or more but not over 112 decitex yarns; such bags or sacks each weighing 25 g/m2 or more but not over 250 g/m2, having a drawstring closure, measuring 77.5 cm or more but not over 127.7 cm in circumference, valued not over $2 each, not presented with or containing sleeping bags (provided for in subheading 4202.92.31)

This classification pertains specifically to sleeping bag carrying bags, often referred to as "stuff sacks," that meet a very precise set of criteria. These bags are constructed from woven taffeta fabric made of polyester, characterized by a thread count between 160 and 210 threads per square inch. Furthermore, the yarns used must fall within a decitex range of 22 to 112. The physical attributes are also strictly defined: the bags must weigh between 25 and 250 grams per square meter, possess a drawstring closure, and have a circumference ranging from 77.5 cm to 127.7 cm. Crucially, these bags must be valued at $2 or less each and cannot be presented with or contain sleeping bags themselves, as those would fall under a different primary classification.

While the broader HTS system encompasses a vast array of goods, from live animals in Chapter 01 to numerous manufactured articles, this specific subheading stands out due to its highly technical and detailed product definition. Unlike general luggage or textile containers, this category is narrowly tailored to a specific accessory for outdoor equipment. It distinguishes itself from typical bags by its specific fabric composition, precise thread count, yarn denier, weight, dimensional constraints, and importantly, its intended use as an auxiliary item for sleeping bags, and its lack of association with the primary product it is designed to carry.

As this classification represents a leaf node within the HTS database, there are no further subcategories that subdivide this specific type of sleeping bag carrying bag. Classification under 9902.12.38 is final for products meeting all the enumerated physical, material, and value-related requirements, and not being presented with sleeping bags. The context provided by Chapter 99, "Temporary legislation; temporary modifications proclaimed pursuant to trade agreements legislation; additional import restrictions proclaimed pursuant to section 22 of the Agricultural Adjustment Act, as amended," indicates that this classification may be subject to specific trade policy adjustments or temporary measures, necessitating careful attention to the prevailing regulations at the time of import.
