Section XVIII - Chapter 91
Clocks and Watches and Parts Thereof
Notes
1. This chapter does not cover:
(a). Clock or watch glasses or weights (classified according to their constituent material);
(b). Watch chains (heading 7113 or 7117, as the case may be);
(c). Parts of general use defined in note 2 to section XV, of base metal (section XV), or similar goods of plastics (chapter 39) or of precious metal or metal clad with precious metal (generally heading 7115); clock or watch springs are, however, to be classifi ed as clock or watch parts (heading 9114);
(d). Bearing balls (heading 7326 or 8482, as the case may be);
(e). Articles of heading 8412 constructed to work without an escapement;
(f). Ball bearings (heading 8482); or
(g). Articles of chapter 85, not yet assembled together or with other components into watch or clock movements or into articles suitable for use solely or principally as parts of such movements (chapter 85).
2. Heading 9101 covers only watches with case wholly of precious metal or of metal clad with precious metal, or of the same materials combined with natural or cultured pearls, or precious or semiprecious stones (natural, synthetic or reconstructed) of heading s 7101 to 7104. Watches with case of base metal inlaid with precious metal fall in heading 9102.
3. For the purposes of this chapter, the expression "watch movements" means devices regulated by a balance wheel and hairspring, quartz crystal or any other system capable of determining intervals of time, with a display or a system to which a mechanical disp lay can be incorporated. Such watch movements shall not exceed 12 mm (0.5 in) in thickness and 50 mm (2.0 in) in width, length or diameter.
4. Except as provided in note 1, movements and other parts suitable for use both in clocks or watches and in other articles (for example, precision instruments) are to be classified in this chapter.
Statistical Notes
1. This chapter does not cover:
(a). The term "watches" embraces timepieces (including timepieces having special features, such as chronographs, calendar watches and watches designed for use in skindiving) of a kind for wearing or carrying on the person whether or not the movement contained t herein conforms to the definition of "watch movements" in note 3, above. Timepieces incorporating a stand, however simple, are not classifiable as watches.
(b). The term "cases" embraces inner and outer cases, containers and housings for movements, together with parts or pieces, such as, but not limited to, rings, feet, posts, bases and outer frames, and any auxiliary or incidental features, which (with appropriat e movements) serve to complete the watches, clocks, time switches and other apparatus provided for in this chapter.
(c). The term "jewels" includes substitutes for jewels.
(d). The term "clock movements" means devices regulated by a balance wheel and hairspring, quartz crystal or any other system capable of determining intervals of time, with a display or a system to which a mechanical display can be incorporated. Such clock move ments shall either exceed 12mm (0.5 in) in thickness or 50 mm (2.0 in) width, length or diameter, or both.
(e). The term "complete watch or clock movements, unassembled or partly assembled (movement sets)" refers to sets which consist of all parts necessary to assemble awatch or clock movement, except that for movements having mechanical displays the set may or may not include the dial and hands.
(f). The term "incomplete watch or clock movements, assembled" refers to:
(i). mechanical movements which are mounted but lack certain parts other than the dial, hands or winding spindle (e.g., the escapement or the barrel bridge),
(ii). battery powered movements with mechanical displays which are mounted but lack certain parts other than the dial, hands, setting spindle or battery (e.g.,the motor), or
(iii). other movements intended to operate with opto-electronic displays which are mounted but lack certain parts other than the battery (e.g., the display).
(g). The term "rough watch or clock movements" refers to sets of unassembled parts for the assembly of watch or clock movements of a kind constructed to work with an escapement. These sets do not include escapement, balance wheel and hairspring or other regulat ing device, mainspring, dial or hands; they therefore consist mainly of the base plate (and any additional plates), bridges, train, motion work, winding and setting mechanism and any additional mechanisms such as automatic winding device, calendar mechanis ms, chronograph, alarm, etc. These sets may be exported with or without a barrel. Each element, intended for use as it is, may itself consist of one simple piece or of several parts fitted inseparably together, but such elements may not themselves be assem bled to each other.
2. Watch straps, watch bands and watch bracelets exported with wrist watches and of a kind normally sold therewith, whether or not attached, are classified with the watch in headings 9101 and 9102. Otherwise, watch straps, watch bands and watch bracelets shal l be classified in heading 9113.
3. Batteries exported with battery powered watches or clocks, or with the complete, assembled movements therefor, and intended for use therewith, are classifiable under the provision for the watch clock or movement. Similarly, batteries exported with a comple te watch or clock movement, unassembled or partly assembled (movement set) or with an incomplete watch or clock movement, assembled, and intended for use therewith, are classifiable under the provision for such movement. Batteries are otherwise classifiabl e in heading 8506 or 8507, whether or not suitable for use with watches or clocks.
