(ij) Semi-finished products
Continuous cast products of solid section, whether or not subjected to primary hot-rolling; and including blanks for

- straight lengths, which if of a thickness less than 4.75mm are of a width measuring at least ten times the thickness or if of a thickness of 4.75mm or more are of a width which exceeds 150mm and measures at least twice the thickness.
Flat-rolled products include those with have been perforated, corrugated or polished, provided that they do not thereby assume the 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 width of 600mm or more, provided that they do not assume the character of articles of 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 poloygons (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 No. 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 definiton of flat-rolled products.
(p) Hollow drill bars and rods
Hollow bars and rods of any cross-section, suitable for drill, of which the greatest external dimension of the cross-section exceeds 15mm but does not exceed 52mm, 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 definiton are to be classified in heading No. 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.
Sub-heading Notes:
- 1.
- In this Chapter the following expressions have the meanings hereby assigned to
them:
(a) Alloy pig iron
Pig iron containing by weight one or more of the following elements in the specified proportions.
- more than 0.2% of chromium
- more than 0.3% of copper
- more than 0.3% of nickel
- more than 0.1% of any of the following elements:
aluminium, molybdenum, titanium, tungsten (wolfram), vanadium.
(b) Non-alloy free-cutting steel

(c) Silicon-electrical steel
Alloy steel containing by weight at least 0.6% but not more than 6% of silicon and not more than 0.08% of carbon. They may also contain by 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 element, at least two of the three elements molybdenum, tungsten and vandium with a combined content by weight of 7% or more, o.6% or more of carbon and 3 to 6% of chormium.
(e) Silicon-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 not any other element in a proportion
that would give the steel the characteristics of another alloys steel.

- For the classification of ferro-alloys in the sub-headings of heading No. 72.02 the following rule should be observed:
A ferro-alloy is considered as binary and classified under the relevant sub-heading (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.
