Zinc and Articles Thereof
1.
In
this
Chapter
the
following
expressions
have
the
meanings
hereby
assigned
to
them:
(a) 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 "modified rectangular") 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.
(b) 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 expression also covers cast or sintered products, of the same forms, 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.
(c) Wire:
Rolled, extruded or drawn products, 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 "modified rectangular") cross-section exceeds one-tenth of the width.
(d) Plates, sheets, strip and foil:
Flat-surfaced
products
(other
than
the
unwrought
products
of
heading
7901),
coiled
or
not,
of
solid
rectangular
(other
than
square)
cross-section
with
or
without
rounded
corners
(including
"modified
rectangles"
of
which
two
opposite
sides
are
convex
arcs,
the
other
two
sides
being
straight,
of
equal
length
and
parallel)
of
a
uniform
thickness,
which
are:
-
of
rectangular
(including
square)
shape
with
a
thickness
not
exceeding
one-tenth
of
the
width,
-
of
a
shape
other
than
rectangular
or
square,
of
any
size,
provided
that
they
do
not
assume
the
character
of
articles
or
products
of
other
headings.
Heading
79.05
applies,
inter
alia,
to
plates,
sheets,
strip
and
foil
with
patterns
(for
example,
grooves,
ribs,
chequers,
tears,
buttons,
lozenges)
and
to
such
products
which
have
been
perforated,
corrugated,
polished
or
coated,
provided
that
they
do
not
thereby
assume
the
character
of
articles
or
products
of
other
headings.
(e) Tubes and pipes:
Hollow products, coiled or not, which have a uniform cross-section with only one enclosed void along their whole length in the shape of circles, ovals, rectangles (including squares), equilateral triangles or regular convex polygons, and which have a uniform wall thickness. Products with a rectangular (including square), equilateral triangular or regular convex polygonal cross-section, which may have corners rounded along their whole length, are also to be considered as tubes and pipes provided the inner and outer cross-sections are concentric and have the same form and orientation. Tubes and pipes of the foregoing cross-sections may be polished, coated, bent, threaded, drilled, waisted, expanded, cone-shaped or fitted with flanges, collars or rings.
SUB-HEADING NOTE
1.
In
this
Chapter
the
following
expressions
have
the
meanings
hereby
assigned
to
them:
(a)
Zinc,
not
alloyed:
Metal
containing
by
weight
at
least
97.5%
of
zinc.
(b)
Zinc
alloys:
Metallic
substances
in
which
zinc
predominates
by
weight
over
each
of
the
other
elements,
provided
that
the
total
content
by
weight
of
such
other
elements
exceeds
2.5%.
(c)
Zinc
dust:
Dust obtained by condensation of zinc vapour, consisting of spherical particles which are finer than zinc powders. At least 80% by weight of the particles pass through a sieve with 63 micrometres (microns) mesh. It must contain at least 85% by weight of metallic zinc.
