- Chapter 91 - NOTES
1.- This Chapter does not cover :
(a) Clock or watch glasses or weights (classified
according to their constituent material);
(b) Watch chains (heading No. 71.13 or 71.17, 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 No. 71.15); clock or
watch springs are, however, to be classified as clock or
watch parts (heading No. 91.14);
(d) Bearing balls (heading No. 73.26 or 84.82, as the
case may be);
(e) Articles of heading No. 84.12 constructed to work
without an escapement;
(f) Ball bearings (heading No. 84.82); 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 No. 91.01 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 semi-precious stones (natural,
synthetic or reconstructed) of headings Nos. 71.01 to
71.04. Watches with case of base metal inlaid with
precious metal fall in heading No. 91.02.
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 display can be
incorporated. Such watch movements shall not exceed 12 mm
in thickness and 50 mm 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.
