9902.15.88 - Electromechanical cat toys, with electrical function supplying power to the moving parts and supporting the mechanical function, each unit comprising an electrical/mechanical "mouse" of plastics enclosed in an approximately 0.61 m diameter textile fabric "pouch," with such "mouse" designed to randomly move around the inside of the pouch (provided for in subheading 8479.89.94)

This HTS category, 9902.15.88, specifically covers electromechanical cat toys designed with an integrated electrical function powering both moving and supporting mechanical components. Each unit comprises a plastic "mouse" designed for random movement within a textile fabric "pouch" of approximately 0.61 meters in diameter. This provision is made for items that would otherwise be classified under subheading 8479.89.94, indicating a temporary or special classification status under Chapter 99.

Given its position within the broader Harmonized Tariff Schedule, this category is distinct from the general provisions found in Chapters 1 through 97. Unlike typical product classifications focusing on the inherent nature of goods (e.g., live animals, machinery, textiles), this subheading falls under Chapter 99, which denotes special provisions such as temporary legislation or modifications. Therefore, its primary distinction from siblings at the same level (which would be other temporary or special provisions) lies in the specific product type it designates for special treatment.

As this is a leaf node, there are no further subcategories. The classification is definitive for the described electromechanical cat toy. The key classification criteria are the integrated electrical and mechanical functions, the presence of a plastic "mouse" designed for random movement, and the enclosing textile fabric pouch of a specified diameter. Any product meeting these precise specifications is intended for classification under this HTS code.
