HEADING 92.03 - KEYBOARD PIPE ORGANS; HARMONIUMS AND SIMILAR KEYBOARD INSTRUMENTS WITH FREE METAL REEDS.

8 COMMODITIES

This heading covers :

(A) Keyboard pipe organs (church-organ type). These are wind instruments in which the movement of the keys is transmitted to the pipes electrically electro- pneumatically or mechanically. These organs comprise the following main parts :

(1) The sound producing group i.e. the pipes placed either in rows of graduated sizes or in groups of similar pipes sounding on the same note. There are two kinds of pipes :

(i) The flue pipe in which the wind on passing from the foot of the pipe into the pipe body is directed across a narrow mouth.

(ii) The reed pipe in which sound is produced by air escaping intermittently from the pipe via a vibrating metal tongue. Pipes may be made of metal (usually a tin-lead alloy or zinc) wood or compressed paperboard.

(2) The ventilation system including : blowing apparatus air-flow regulators wind-trunks (which carry the wind to the wind-chests) and wind-chests (wooden cases in which the air is compressed).

(3) The playing mechanisms (e.g. the manual (keyboard) and pedal board actions different registers (stops) the system of combining registers and couplers) and various accessories (e.g. tremulants cymbelstern harp). The heading also covers the console and the organ case (i.e. the woodwork in which the organ is contained and which is usually of decorative design) when presented with the organ. If presented separately they are excluded (heading 92.09).

This heading does not include orchestrions street organs and similar pipe instruments not fitted with a keyboard but operated either automatically or by a handle (heading 92.08). Electronic organs are classified in heading 92.07.

(B) Harmoniums and similar keyboard instruments with free metal reeds without pipes and principally intended for accompanying vocal music. In these instruments sound is produced by metal tongues (free reeds) which vibrate under wind pressure supplied by bellows or electrically. The bellows are actuated by pedals or levers.
