9902.16.27 - Litterboxes, each with self-contained electric motor powered by an external adapter that plugs into a wall socket or electrical outlet and may have batteries for back-up, such devices which rake and/or disperse cat waste into a compartment after a certain amount of time has passed once the mechanism is triggered by cat entering the litterbox; the foregoing designed for domestic use (provided for in subheading 8509.80.50)

This HTS classification covers specialized litterboxes designed for domestic animal use, specifically cats. These devices incorporate an electric motor, powered by an external adapter, and may include battery backup. Their primary function is automatic waste management, employing mechanisms to rake or disperse waste into a designated compartment after being triggered by the pet's entry.

While HTS Chapter 99 generally deals with temporary legislation and import restrictions, this specific code (9902.16.27) falls under a temporary modification related to specific goods. It's crucial to differentiate this from the primary HTS Chapters that classify general household appliances (like those in Chapter 85, to which this provision refers) as this code represents a specific temporary import treatment rather than the fundamental classification of the item's components. This code acts as a specialized override for the standard classification based on a particular trade agreement or restriction.

As this is a leaf node, there are no further subcategories. Classification under this specific code depends entirely on meeting the detailed product description and the prevailing temporary legislation that it represents. Importers must ensure their product precisely matches the self-raking/dispersing functionality, electric motor operation, and domestic use criteria to be correctly classified here, rather than under its base HTS classification (which, as noted, would likely be in subheading 8509.80.50).
