9205.90.19.00 - Mouth organs

This classification pertains to mouth organs, commonly known as harmonicas. These are free-reed wind instruments that produce sound when air is blown or drawn through reeds. They are characterized by their compact size and the direct manipulation of air by the player's mouth and diaphragm to control pitch and tone.

Distinguishing mouth organs from their sibling category, accordions and similar instruments, lies in their fundamental design and method of air modulation. While accordions utilize bellows to force air across reeds and feature a keyboard for pitch selection, mouth organs rely solely on the player's breath and typically have a comb with holes over which reeds are mounted.

As a leaf node within the HTS classification system, 9205.90.19.00 represents a specific and final category for mouth organs. Further subdivision is not required, and classification at this level is determined by the specific characteristics defining a mouth organ as distinct from other wind instruments.
