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.

Hollow bars and rods of iron or steel not conforming to this definition are to be classified in heading [7304](/headings/7304). 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. ### Subheading 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 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 subheadings of heading [7202](/headings/7202) 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 note 1(c) to this Chapter; 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 note 1(c) to this Chapter must each exceed 10% by weight. ### Additional chapter note The following expressions have the meanings hereby assigned to them: - 'Electrical': for the purposes of subheadings [7209 16 10](/subheadings/7209161000-80), [7209 17 10](/subheadings/7209171000-80), [7209 18 10](/subheadings/7209181000-80), [7209 26 10](/subheadings/7209261000-80), [7209 27 10](/subheadings/7209271000-80), [7209 28 10](/subheadings/7209281000-80) and [7211 23 20](/subheadings/7211232000-80), flat-rolled products which under a current of 50 Hz and a magnetic flux of 1 T have a watt-loss per kg, calculated by the Epstein method, of: - 2.1 W or less, when their thickness does not exceed 0.20mm, - 3.6 W or less, when their thickness is not less than 0.20mm but less than 0.60mm, - 6 W or less, when their thickness is not less than 0.60mm but not greater than 1.50mm. - 'Tinplate': for the purposes of subheadings [7210 12 20](/subheadings/7210122000-80), [7210 70 10](/subheadings/7210701000-80), [7212 10 10](/subheadings/7212101000-80) and [7212 40 20](/subheadings/7212402000-80), flat-rolled products (of a thickness of less than 0.5mm) coated with a layer of metal containing, by weight, 97% or more of tin. - 'Tool steel': for the purposes of subheadings [7224 10 10](/subheadings/7224101000-80), [7224 90 02](/subheadings/7224900200-80), [7225 30 10](/subheadings/7225301000-80), [7225 40 12](/subheadings/7225401200-80), [7226 91 20](/subheadings/7226912000-80), [7228 30 20](/subheadings/7228302000-80), [7228 40 10](/subheadings/7228401000-80), [7228 50 20](/subheadings/7228502000-80) and [7228 60 20](/subheadings/7228602000-80), alloy steels, other than stainless or high-speed steel, containing, by weight, one of the following compositions, with or without other elements: - less than 0.6% of carbon and 0.7% or more of silicon and 0.05% or more of vanadium or 4% or more of tungsten; - 0.8% or more of carbon and 0.05% or more of vanadium; - more than 1.2% of carbon and not less than 11% but not more than 15% of chromium; - 0.16% or more but not more than 0.5% of carbon and 3.8% or more but not more than 4.3% of nickel and 1.1% or more but not more than 1.5% of chromium and 0.15% or more but not more than 0.5% of molybdenum; 0.3% or more but not more than 0.5% of carbon and 1.4% or more but not more than 2.1% of chromium and 0.15% or more but not more than 0.5% of molybdenum and less than 1.2% of nickel; - 0.3% or more of carbon and less than 5.2% of chromium and 0.65% or more of molybdenum or 0.4% or more of tungsten; - 0.5% or more but not more than 0.6% of carbon and 1.25% or more but not more than 1.8% of nickel and 0.5% or more but not more than 1.2% of chromium and 0.15% or more but not more than 0.5% of molybdenum

Throughout the classification, the expression 'parts of general use' means: a. articles of heading [7307](/headings/7307), [7312](/headings/7312), [7315](/headings/7315), [7317](/headings/7317) or [7318](/headings/7318) and similar articles of other base metal, other than articles specially designed for use exclusively in implants in medical, surgical, dental or veterinary sciences (heading [9021](/headings/9021)) b. springs and leaves for springs, of base metal, other than clock or watch springs (heading [9114](/headings/9114)); and c. articles of heading [8301](/headings/8301), [8302](/headings/8302), [8308](/headings/8308), [8310](/headings/8310) and frames and mirrors, of base metal, of heading [8306](/headings/8306). In Chapters [73](/chapters/73) to [76](/chapters/76) and [78](/chapters/78) to [82](/chapters/82) (but not in heading [7315](/headings/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](/chapters/83), the articles of Chapter [82](/chapters/82) or [83](/chapters/83) are excluded from Chapters [72](/chapters/72) to 76 and [78](/chapters/78) to [81](/chapters/81). 3. Throughout the classification, 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 the classification, the term 'cermets' means products containing a microscopic heterogeneous combination of a 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](/chapters/72) and [74](/chapters/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 cermets) and intermetallic compounds. 6. Unless the context otherwise requires, any reference in the classification 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 General 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. c. A cermet of heading [8113](/headings/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
  • All metal waste and scrap, 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 1mm. 9. For the purposes of Chapters [74](/chapters/74) to [76](/chapters/76) and [78](/chapters/78) to [81](/chapters/81), the following expressions have the meanings hereby assigned to them :
  • (a) Bars and rods
  • Rolled, extruded, drawn or forged products, not in coils, which have a uniform solid cross-section along their whole length in the shape of circles, ovals, rectangles (including squares), equilateral triangles or regular 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). Products with a rectangular (including square), tariangular or polygonal cross-section may have corners rounded along their whole length. The thickness of such products which have a rectangular (including “modified rectangular”) cross-section exceeds one-tenth of the width. The expression also covers cast or sintered products, of the same forms and dimensions, which have been subsequently worked after production (otherwise than by simple trimming or de-scaling), provided that they have not thereby assumed the character of articles or products of other headings. Wire-bars and billets of Chapter [74](/chapters/74) with their ends tapered or otherwise worked simply to facilitate their entry into machines for converting them into, for example, drawing stock (wire-rod) or tubes, are however to be taken to be unwrought copper of heading [7403](/headings/7403). This provision applies mutatis mutandis to the products of Chapter [81](/chapters/81).
  • (b) Profiles
  • Rolled, extruded, drawn, forged or formed products, coiled or not, of a uniform cross-section along their whole length, which do not conform to any of the definitions of bars, rods, wire, plates, sheets, strip, foil, tubes or pipes. The expression also covers cast or sintered products, of the same forms, which have been subsequently worked after production (otherwise than by simple trimming or de-scaling), provided that they have not thereby assumed the character of articles or products of other headings.
  • (c) Wire
  • Rolled, extruded or drawn products, in coils, which have a uniform solid cross-section along their whole length in the shape of circles, ovals, rectangles (including squares), equilateral triangles or regular 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). Products with a rectangular (including square), triangular or polygonal cross-section may have corners rounded along their whole length. The thickness of such products which have a rectangular (including “modified rectangular”) cross-section exceeds one-tenth of the width.
  • (d) Plates, sheets, strip and foil
  • Flat-surfaced products (other than the unwrought products of heading [8001](/headings/8001)), coiled or not, of solid rectangular (other than square) cross-section with or without rounded corners (including “modified rectangles” of which two opposite sides are convex arcs, the other two sides being straight, of equal length and parallel) of a uniform thickness, which are : - of rectangular (including square) shape with a thickness not exceeding one-tenth of the width; - of a shape other than rectangular or square, of any size, provided that they do not assume the character of articles or products of other headings. Headings for plates, sheets, strip, and foil apply, inter alia, to plates, sheets, strip, and foil with patterns (for example, grooves, ribs, chequers, tears, buttons, lozenges) and to such products which have been perforated, corrugated, polished or coated, provided that they do not thereby assume the character of articles or products of other headings.
  • (e) Tubes and pipes
  • Hollow products, coiled or not, which have a uniform cross-section with only one enclosed void along their whole length in the shape of circles, ovals, rectangles (including squares), equilateral triangles or regular convex polygons, and which have a uniform wall thickness. Products with a rectangular (including square), equilateral triangular or regular convex polygonal cross-section, which may have corners rounded along their whole length, are also to be considered as tubes and pipes provided the inner and outer cross-sections are concentric and have the same form and orientation. Tubes and pipes of the foregoing cross-sections may be polished, coated, bent, threaded, drilled, waisted, expanded, cone-shaped or fitted with flanges, collars or rings
