9902.16.30 - Feeders designed for use with fish, each with a self-contained electric motor powered by batteries, with retaining clips or clamps to attach to a household aquarium, the foregoing which can be programmed to disperse various quantities of food at preset times (provided for in subheading 8509.80.50)

This HTS category, 9902.16.30, specifically covers automatic aquarium fish feeders that are designed for household use. The key characteristics defining these products include their self-contained electric motor powered by batteries, and the presence of retaining clips or clamps intended for attachment to a household aquarium. Crucially, these feeders are programmable, allowing for the dispersal of various food quantities at predetermined times.

As a temporary provision within Chapter 99, this classification is distinct from the primary HTS chapters that would otherwise cover general electrical appliances or consumer goods. Unlike the broader categories found elsewhere in the HTS, such as those for general electrical machinery or household appliances (which might include items like blenders or toasters), this code is reserved for this very specific type of product due to temporary legislative or trade agreement modifications. It is important to note that this is a leaf node, meaning there are no further subdivisions within this particular HTS code. Classification into this sub-heading hinges on the unique combination of battery power, aquarium-specific attachment mechanisms, and programmable feeding functionality.
