Flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, hot-rolled, not clad, plated or coated The term ‘re-rolling’ for the purposes of the subheadings of this heading is limited to the process by which the metal is passed between inversely rotating rolls and is thereby reduced in thickness. This process may also have the effect of improving the metal surface or its mechanical properties. The term ‘re-rolling’ does not however cover the ‘skin-pass’ process which causes a slight reduction is thickness or other processes under which the metal is shaped but not reduced in thickness. Other These subheadings cover hot-rolled flat products which have undergone one or more of the surface treatments mentioned in the HS Explanatory Note to heading 7208 , second paragraph, (3) to (5) and/or cut to shape other than square or rectangular. These subheadings also cover hot-rolled flat products which, after rolling, have undergone working such as corrugating, perforation, bevelling or rounding at the edges. However, products with patterns in relief resulting directly from rolling, are not considered as having undergone working in the meaning of these subheadings.

This chapter defines key ferrous metallurgy terms. 'Pig iron' means iron-carbon alloys not usefully malleable, containing more than 2% carbon by weight and possibly containing other elements within specified limits (e.g. chromium max 10%, manganese max 6%). 'Stainless steel' means alloy steels containing by weight 1.2% or less of carbon and 10.5% or more of chromium, with or without other elements. 'Other alloy steel' means steels not meeting the definition of stainless steel but containing by weight one or more specified elements above minimum thresholds (e.g., aluminium 0.3%, boron 0.0008%, chromium 0.3%, cobalt 0.3%, etc.). The chapter further defines flat-rolled products, bars and rods, hollow profiles, ingots, semi-finished products and specific forms. Iron and steel products are classified by carbon content, alloying elements, and the form of working (hot-rolled, cold-rolled, coated, etc.).

Section noteNotes to Section XV — Base metals and articles of base metal

1. This Section does not cover: (a) prepared paints, inks or other products with a basis of metallic flakes or powder (headings 3207 to 3210, 3212, 3213 or 3215); (b) ferrocerium or other pyrophoric alloys (heading 3606); (c) headgear or parts thereof of heading 6506 or 6507; (d) umbrella frames or other articles of Chapter 66; (e) goods of Chapter 71 (for example, precious metal alloys, base metal clad with precious metal, imitation jewellery); (f) articles of Section XVI (machinery and mechanical appliances, electrical equipment); (g) assembled railway or tramway track (heading 8608) or other articles of Section XVII (vehicles, aircraft, vessels); (h) instruments or apparatus of Section XVIII, including clock or watch springs; (ij) lead shot prepared for ammunition (heading 9306) or other articles of Section XIX (arms and ammunition); (k) articles of Chapter 94 (furniture, lamps, illuminated signs, prefabricated buildings); (l) articles of Chapter 95 (toys, games, sports requisites); (m) hand sieves, buttons, pens, pencils, pen-holders, monopods, bipods, tripods and similar articles or other articles of Chapter 96; (n) articles of Chapter 97 (works of art). 2.

In Chapters 73 to 76 and 78 to 82, references to parts of goods do not include references to parts of general use as defined above. 3. Throughout the Nomenclature, 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 (celtium), indium, niobium (columbium), rhenium and thallium. 4. Throughout the Nomenclature, the term 'cermets' means products containing a microscopic heterogeneous combination of a metallic component and a ceramic component, including sintered metal carbides. 5. Classification of alloys (other than ferro-alloys and master alloys as defined in Chapters 72 and 74): alloys of base metals with each other are to be classified as alloys of the metal which predominates by weight over each of the other metals. Alloys of base metals not elsewhere specified or included are to be classified as articles of the metal predominating by weight.
