1. In this Chapter the following expressions have the meanings hereby
assigned to them:

(a) Alloy Pig Iron:

Pig iron containing, by weight, one ore 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:

Non-alloy steel containing, by weight, one or more of the following elements
in the specified proportions:



- 0.08% or more of sulphur

- 0.1% or more of lead

- more than 0.05% of selenium

- more than 0.01% of tellurium

- more than 0.05% of bismuth.

(c) Silicon-electrical Steel:

Alloy steels 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 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 sub-headings of heading 7202
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.
