The article in question is a bubble machine, identified as the Party Mini Bubble Machine, model number SL-9903R. Included with the machine is a four-ounce bottle of bubble juice and an AC adapter. You indicate that the machine can also operate on two AA batteries. In operation, the bubble juice is poured into the front tray, which when turned on causes the front wheel to rotate, picking up a small quantity of bubble juice, which is then “blown out” into the room when the ring reaches the top of the machine. Since the Party Mini Bubble Machine is not designed to amuse, but to merely dispense bubbles, it is not considered to be a toy, for tariff classification purposes.
