(g)
Remelting scrap ingots of iron or steel
Products
roughly cast in the form of ingots without feeder-heads or hot tops, or
of pigs, having obvious surface faults and not complying with the
chemical composition of pig iron, spiegeleisen or ferro-alloys.
(h)
Granules
Products
of which less than 90 % by weight passes through a sieve with a mesh
aperture of 1 mm and of which 90 % or more by weight passes through a
sieve with a mesh aperture of 5 mm.
(ij)
Semi-finished products
Continuous
cast products of solid section, whether or not subjected to primary
hot-rolling; and
Other
products of solid section, which have not been further worked than
subjected to primary hot-rolling or roughly shaped by forging, including
blanks for angles, shapes or sections.
These
products are not presented in coils.
(k)
Flat-rolled products
Rolled
products of solid rectangular (other than square) cross-section, which
do not conform to the definition at (ij) above in the form of :
-
coils of successively superimposed layers, or
-
straight lengths, which if of a thickness less than 4.75 mm are of a
width measuring at least ten times the thickness or if of a thickness of
4.75 mm or more are of a width which exceeds 150 mm
and measures at least twice the thickness.
Flat-rolled
products include those with patterns in relief derived directly from
rolling (for example, grooves, ribs, chequers, tears, buttons, lozenges)
and those which have been perforated, corrugated or polished, provided
that they do not thereby assume the character of articles or products of
other headings.
Flat-rolled
products of a shape other than rectangular or square, of any size, are
to be classified as products of a width of 600 mm or more, provided that
they do not assume the character of articles or products of other
headings.
(l)
Bars and rods, hot-rolled, in irregularly wound coils
Hot-rolled products in irregularly wound coils, which have a solid
cross-section in the shape of circles, segments of circles, ovals,
rectangles (including squares), triangles or other 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).
These products may have indentations, ribs, grooves or other
deformations produced during the rolling process (reinforcing bars and
rods).
(m)Other
bars and rods
Products
which do not conform to any of the definitions at (ij), (k) or (l) above
or to the definition of wire, which have a uniform solid cross-section
along their whole length in the shape of circles, segments of circles,
ovals, rectangles (including squares), triangles or other 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).
These products may :
-
have indentations, ribs, grooves or other deformations produced during
the rolling process
(reinforcing bars and rods);
-
be twisted after rolling.
(n)
Angles, shapes and sections
Products
having a uniform solid cross-section along their whole length which do
not conform to any of the definitions at (ij), (k), (l) or (m) above or
to the definition of wire.
Chapter 72 does not include products of heading 73.01 or 73.02.
(o)
Wire
Cold-formed products in coils, of any uniform solid cross-section along
their whole length, which
do not conform to the definition of flat-rolled products.
(p)
Hollow drill bars and rods
Hollow bars and rods of any cross-section, suitable for drills, of which
the greatest external
dimension of the cross-section exceeds 15 mm but does not exceed 52 mm,
and of which the
greatest internal dimension does not exceed one half of the greatest
external dimension. Hollow
bars and rods of iron or steel not conforming to this definition are to
be classified in heading 73.04.
2. -
Ferrous metals clad with another ferrous metal are to be classified as
products of the ferrous metal predominating by weight.
3. -
Iron or steel products obtained by electrolytic deposition, by pressure
casting or by sintering are to be classified, according to their form,
their composition and their appearance, in the headings of this Chapter
appropriate to similar hot-rolled products.

weight not more than 1 % of aluminium but no other element in a
proportion that would give the steel the characteristics of another
alloy steel.
(d)
High speed steel
Alloy
steels containing, with or without other elements, at least two of the
three elements
molybdenum, tungsten and vanadium with a combined content by weight of 7
% or more, 0.6 % or
more of carbon and 3 to 6 % of chromium.
(e)
Silico-manganese steel
Alloy
steels containing by weight :
-
not more than 0.7 % of carbon,
-
0.5 % or more but not more than 1.9 % of manganese, and
-
0.6 % or more but not more than 2.3 % of silicon, but no other element
in a proportion that would give the steel the characteristics of another
alloy steel.
2. -
For the classification of ferro-alloys in the subheadings of heading
72.02 the following rule should be observed :
A ferro-alloy is considered as binary and classified under the relevant
subheading (if it exists) if only one of the alloy elements exceeds the
minimum percentage laid down in Chapter Note 1 (c); by analogy, it is
considered respectively as ternary or quaternary if two or three alloy
elements exceed the minimum percentage.
For the application of this rule the unspecified “other elements”
referred to in Chapter Note 1 (c) must each exceed 10 % by weight.
