9902.13.84 - Smartphone cases, each attached to integral adjustable armbands wholly of textile materials, with such case of polyester-laminated neoprene, incorporating a clear plastic window for visual access to the smartphone screen and a small opening for headphone wires, whether or not with decorative plastic overlay (provided for in subheading 6307.90.98)

This HTS classification, 9902.13.84, pertains to specialized smartphone cases designed for attachment to adjustable armbands. The integral armbands are constructed entirely of textile materials. The cases themselves are characterized by a polyester-laminated neoprene construction, featuring a transparent plastic window for screen visibility and a dedicated opening for headphone wires. The presence of decorative plastic overlays is permissible and does not alter the classification. This specific provision falls under Chapter 99, indicating temporary legislation or modifications, and is provided for in subheading 6307.90.98, which typically covers other made up textile articles.

As this is a leaf node within Chapter 99, there are no further subcategories for this particular provision. The strength of this classification lies in its specific combination of features: the integrated textile armband, the material composition of the case (polyester-laminated neoprene), and the functional elements like the screen window and headphone port. Unlike broader categories for general textile articles or simple smartphone cases, this classification is reserved for the integrated armband-case system. When classifying, customs professionals should focus on the distinct dual functionality and the specific materials used, ensuring it meets all the descriptive criteria to differentiate it from other, less specialized, textile goods.
