(f) Articles of Section XVI (machinery, mechanical appliances and electrical goods);
(g) Assembled railway or tramway track (heading No. 8608) or other articles of Section XVII (vehicle, ships and boats, aircrafts);
(h) Instruments or apparatus of Section XVIII, including clock or watch springs;
(ij) Lead shot prepared for ammunition (heading No. 9306) or other articles of Section XIX (Arms and Ammunition);
(k) Articles of Chapter 94 (for example, furniture, mattress supports, lamps and lighting fittings, illuminated signs, prefabricated buildings);
(l) Articles of Chapter 95 (for example, toys, games, sports requisites);
(m) Hand sieves, buttons, pens, pencil-holders, pen nibs or other articles of Chapter 96 (miscellaneous manufactured articles); or
(n) Articles of Chapter 97 (for example, works of art).

2 Throughout this Schedule, the expression "parts of general use" means:
(a) Articles of heading Nos. 7307, 7312, 7315, 7317 or 7318 and similar articles of other base metal;
(b) Springs and leaves for springs, of base metal, other than clock or watch springs (heading No. 9114); and
( c) Articles of heading No. 8301, 8302, 8308, 8310 and frames and mirrors, of base metal, of heading No. 8306.
In Chapters 73, 74, 75 and 76 and 78, 79, 80, 81 and 82 (but not in heading No. 7315) references to parts of goods do not include references to parts of general use as defined above.
Subject to the preceding paragraph and to Note 1 to Chapter 83, the articles of Chapters 82 or 83 are excluded from Chapters 72, 73, 74, 75 and 76 and 78, 79, 80 and 81

3.Throughout this Schedule, the expression "Base metals" means: Iron and steel, copper, nickel, aluminium, lead, zinc, tin, tungsten, (wolfram) molybdenum, tantalum, magnesium, cobalt, bismuth, cadmium, titanium, zirconium, antimony, manganese, beryllium, chromium, germanium, vanadium, gallium, hafnium, indium, niobium (columbium), rhenium and thallium.

4. Throughout this Schedule, the term "cermets" means products containing a microscopic heterogeneous combination of metallic component and a ceramic component. The term "cermets" includes sintered metal carbides (metal carbides sintered with a metal).

5. Classification of alloys other than Ferro alloys and master alloys as defined in Chapters 72 and 74
(a) An alloy of base metals is to be classified as an alloy of the metal which predominates by weight over each of the other metals;
(b) An alloy composed of base metals of this Section and of elements not falling within this Section is to be treated as an alloy of base metals of this Section if the total weight of such metals equals or exceeds the total weight of the other elements present;
( c) In this Section the term "alloys" includes sintered mixtures of metal powders, heterogeneous intimate mixtures obtained by melting (other than cerments) and intermetallic compounds.

6. Unless the context otherwise requires, any reference in this Schedule, to a base metal includes a reference to alloys which, by virtue of Note 5 above, are to be classified as alloys of that metal.

7. Classification of composite articles:
Except where the headings otherwise require, articles of base metal (including articles of mixed materials treated as articles of base metal under the Interpretative Rules) containing two or more base metals are to be treated as articles of the base metal predominating by weight over each of the other metals. For this purpose;
(a) Iron and steel, or different kinds of iron or steel, are regarded as one and the same metal;
(b) An alloy is regarded as being entirely composed of that metal as an alloy of which, by virtue of Note 5, it is classified; and
( c) A cement of heading No. 8113 is regarded as a single base metal.

8. In this Section, the following expressions have the meanings hereby assigned to them;
(a) Waste and scrap:
Metal waste and scrap from the manufacture or mechanical working of metals, and metal goods definitely not usable as such because of breakage, cutting-up, wear or other reasons.
(b) Powders:
Products of which 90% or more by weight passes through a sieve having a mesh aperture of 1 mm.
