70.03 - Cast glass and rolled glass, in sheets or profies, whether or not having an absorbent, reflecting or non-reflecting layer, but not otherwise worked. - Non-wired sheets : 7003.12 - - Coloured throu hout the mass (body tinted), opacified, flashed or having an absorbent, refl ecting or non-reflecting layer - - Other 7003.20 - Wired sheets 7003.19 7003.30 - Profiles This heading covers all types of cast glass and rolled lass provided it is in sheets (whatever the thickness and whether or not cut to shape), or pro les, whether or not having an absorbent, reflecting or non-reflecting layer, but not otherwise worked. B It includes : (A) Unworked plate glass. This is generally non-trans arent on account of its grained or rough surfaces. It may also be artifictally coloured in t e mass by means of metallic oxides or other salts. Surface ground or polished plate glass is excluded (heading 70.05). k' (B) A category of non-transparent glass which is more or less opacified in the mass and sometimes completely opaque. It is often made to resemble marble, porcelain (china) or alabaster in ap earance. Thxs e of glass is made in white, black and other colours, plain or veined, an is used for acing walls, for the manufacture of tops for washstands, counters, desks, tables, operating tables, etc., of tablets for gravestones, of advertising boards, signs, etc. P. S polishing on one or both unworked state this lass bear traces of sand resu ting rough surface in order to This type of glass may be intended for faces, but when so treated it is excluded shows marks resulting from contact from the casting. Certain opal facilitate fixing. f (C) A range of non-transparent glass, with an irre lar surface obtained durin manufacture. This grou includes rough cast glass, cathe a1 glass, hammered cathe a1 glass, etc.; f i ed-ro led glass having one surface impressed with patterns (stripes, diamond patterns, ri ges, etc.); corrugated lass and cast so-called anti ue glass i.e., glass contamin bubbles, or crackled on t e surface, or with other de lberate " efects "). Glass of t ese air types, which may also be coloured in the mass, is used for the windows of factories, warehouses, offices, bathrooms and, in general, all premises where light is required but with varying degrees of obscuration. r P P i % Owing to the nature of the processes by which they are made, the types of glass in this category are not rendered plane by further processing. As already stated, this heading covers only cast glass and rolled glass. In the rolling process, the molten glass is passed between rollers from which it emerges either as a continuous ribbon or in sheets or profiles. It is then carried mechanically into a lehr. Pass It is durin the castiug or rolling rocesses that the surfaces of figured, hammered, etc., impressed? In the casting methot either engraved casting tables or an en aved roller o m the patterns in the semi-molten lass. In the rolling method, the desired e fects are obtained by means of the final roller, whic is engraved. F % r es of lass described above ma have holes obtained during manufacture, or m y be The& late, gured, cathedral and simi ar types of glass are sometimes wired where protection wire against the danger of s linters on disintegration or breakage is required, thus d i n g it suitable for building purposes. %ired glass is almost always obtained by embedding a network of steel wire in the soft glass while it is being rolled. # Glass classified in this heading may have been flashed, generally with glass of another colour, during the rnanufacturin process or may have been coated with an absorbent, reflecting or nonreflecting Iayer, but not urther worked. f The heading excludes not on1 cast lass and rolled lass which, b reason of subsequent processin ,fall in other headings (e.g., headkg 7k05, 70.06, 70.f8 or 70.09), gut also safety glass (heading ?0.07) which may have been subject to rolling during manufacture.
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 %.
