70.02 - Glass in balls (other than microspheres of heading 70.18), rods or tubes, unworked. - Balls 7002.20 - Rods - Tubes : 7002.31 - - Of hsed quartz or other fused silica 7002.32 - - Of other glass having a linear coefficient of expansion not exceeding 5 x lod 7002.10 per Kelvin within a temperature range of 0 "C to 300 "C 7002.39 - - Other This heading covers : (1) Solid glass balls, which are generally manufactured by moulding or ressing or on doublescrew machines, and which may be used, inter alia, as raw materia for the production of fibre, or for the preparation of lithographic plates. P (2) Glass rods and tubing of various diameters, which are general1 obtained by drawing combined with blowing in the case of tubing); they may be used or many py s e s (c.g $or chemical or industrial apparatus; in the textile industry; for further man actwe mnii thermometers, ampoules, electric or electronic bulbs and valves, or ornaments). Certain tubes for fluorescent li tin (used mainly for advertising purposes) are drawn with partitions running throug the ength. ?' !? 7 This group includes " enamel " glass, in bars, rods or tubes (" enamel " glass is defined in the Explanatory Note to heading 70.01). Balls of this heading must be unworked; similarly rod and tubing must be unworked (i.e., as obtained direct from the drawing process or merely cut into lengths the ends of which may have been simply smoothed). The heading excludes balls, rod and tubing made into finished articles or parts of finished articles reco isable as such; these are classified under the a pro riate heading e.g., heading 70.11, 70.17 or 7&8, or Cha tcr 90). If worked, but not recognisab e as eing intended or a particular purposq they fall in heading 7 .20. ! P % This headin includes tubes (whether or not cut to len ) of glass which has had fluorescent material ad ed to it in the mass. On the other han , tubes coated inside with fluorescent material, whether or not otherwise worked, are excluded (heading 70.11). % $" Glass balls having the character of toys (veined lass marbles put up in any form, and lass balls of an kind ut up in packets for the amusement of chilgen) are class~fiedm heading 95.03. &ass balls, whicl have geen ground after shaping, used for stoppering certain bottles fall in heading 70.10. The heading also excludes the spherical glass grains (microspheres, not exceeding 1 mm in diametv) used, for exam le, for the manufacture of panels for road signs, reflecting signs or cinema screens, or m the cleaning o aeroplane jet engines or metallic surfaces (heading 70.18). ?
1.- This Chapter does not cover : (a) Goods of heading 32.07 (for example, vitrifiable enamels and glazes, glass frit, other glass in the form of powder, granules or flakes); (b) Articles of Chapter 71 (for example, imitation jewellery); (c) Optical fibre cables of heading 85.44, electrical insulators (heading 85.46) or fittings of insulating material of heading 85.47; (d) Front windscreens (windshields), rear windows and other windows, framed, for vehicles of Chapters 86 to 88; (e) Front windscreens (windshields), rear windows and other windows, whether or not framed, incorporating heating devices or other electrical or electronic devices, for vehicles of Chapters 86 to 88; (f) Optical fibres, optically worked optical elements, hypodermic syringes, artificial eyes, thermometers, barometers, hydrometers or other articles of Chapter 90; (g) Luminaires and lighting fittings, illuminated signs, illuminated name-plates or the like, having a permanently fixed light source, or parts thereof of heading 94.05; (h) Toys, games, sports requisites, Christmas tree ornaments or other articles of Chapter 95 (excluding glass eyes without mechanisms for dolls or for other articles of Chapter 95); or (ij) Buttons, fitted vacuum flasks, scent or similar sprays or other articles of Chapter 96. 2.- For the purposes of headings 70.03, 70.04 and 70.05 : (a) glass is not regarded as “worked” by reason of any process it has undergone before annealing; (b) cutting to shape does not affect the classification of glass in sheets; (c) the expression “absorbent, reflecting or non-reflecting layer” means a microscopically thin coating of metal or of a chemical compound (for example, metal oxide) which absorbs, for example, infra- red light or improves the reflecting qualities of the glass while still allowing it to retain a degree of transparency or translucency; or which prevents light from being reflected on the surface of the glass. 3.- The products referred to in heading 70.06 remain classified in that heading whether or not they have the character of articles. 4.- For the purposes of heading 70.19, the expression “glass wool” means : (a) Mineral wools with a silica (SiO ) content not less than 60 % by weight; 2 (b) Mineral wools with a silica (SiO ) content less than 60 % but with an alkaline oxide (K O or Na O) 2 2 2 content exceeding 5 % by weight or a boric oxide (BO ) content exceeding 2 % by weight. 2 3 Mineral wools which do not comply with the above specifications fall in heading 68.06. 5.- Throughout the Nomenclature, the expression “glass” includes fused quartz and other fused silica. Subheading Note. 1.- For the purposes of subheadings 7013.22, 7013.33, 7013.41 and 7013.91, the expression “lead crystal” means only glass having a minimum lead monoxide (PbO) content by weight of 24 %.
