Chapter notes
Note.
1. In this Chapter the following expressions have the
meanings hereby assigned to them:
(a) Refined copper
Metal containing at least 99.85% by weight of copper; or
Metal containing at least 97.5% by weight of copper,
provided that the content by weight of any other element
does not exceed the limit specified in the following
table:
TABLE - Other elements
___________________________________________________________
Element | Limiting content % by weight
___________________________________________________________
Ag Silver | 0.25
As Arsenic | 0.5
Cd Cadmium | 1.3
Cr Chromium | 1.4
Mg Magnesium | 0.8
Pb Lead | 1.5
S Sulphur | 0.7
Sn Tin | 0.8
Te Tellurium | 0.8
Zn Zinc | 1
Zr Zirconium | 0.3
Other elements *, each | 0.3
___________________________________________________________
*Other elements are, for example, Al, Be, Co, Fe, Mn, Ni,
Si.
(b) Copper alloys
Metallic substances other than unrefined copper in
which copper predominates by weight over each of
the other elements, provided that:
(i) the content by weight of at least one of the
other elements is greater than the limit
specified in the foregoing table; or
(ii) the total content by weight of such other
elements exceeds 2.5%.
(c) Master alloys
Alloys containing with other elements more than 10%
by weight of copper, not usefully malleable and
commonly used as an additive in the manufacture of
other alloys or as de oxidants, de sulphurising
agents or for similar uses in the metallurgy of
non ferrous metals. However, copper phosphide
(phosphor copper) containing more than 15% by
weight of phosphorus falls in heading 2848.00.00.
(d) Bars and rods
Rolled, extruded, drawn or forged products, not in
coils, which have a uniform solid cross section
along their whole length in the shape of circles,
ovals, rectangles (including squares), equilateral
triangles or regular convex polygons (including
"flattened circles" and "modified rectangles", of
which two opposite sides are convex arcs, the other
two sides being straight, of equal length and
parallel). Products with a rectangular (including
square), triangular or polygonal cross section may
have corners rounded along their whole length. The
thickness of such products which have a rectangular
(including omodified rectangularo) cross section
exceeds one tenth of the width. The expression
also covers cast or sintered products, of the same
forms and dimensions, which have been subsequently
worked after production (otherwise than by simple
trimming or de scaling), provided that they have
not thereby assumed the character of articles or
products of other headings.
Wire bars and billets with their ends tapered or
otherwise worked simply to facilitate their entry
into machines for converting them into, for example,
drawing stock (wire rod) or tubes, are however to
be taken to be unwrought copper of heading 74.03.
(e) Profiles
Rolled, extruded, drawn, forged or formed products,
coiled or not, of a uniform cross section along
their whole length, which do not conform to any of
the definitions of bars, rods, wire, plates, sheets,
strip, foil, tubes or pipes. The
