25.04 - Natural graphite. 2504.10 2504.90 - In powder or in flakes - Other (otherwise known as plumbago or black lead) is a variety of carbon its lustre and its property of markin paper (for which reason it is used as parent specific gravity varies, accor ng to its degree of purity, between 1.9 content of the purest grades ranges from 90 to 96 %, whlle the cheaper grades contain only 40 to 80 %. Natural graphite remains in this heading when it has been heat treated merely to remove impurities. Apart from its use in encils, natural aphite is also used as a polish, for the manufacture of crucibles and other re actmy articles, L a c e electrodes and other electric parts. R The heading excludes artificial graphite (which closely resembles natural graphite but has a higher de of purity and lower specific graaty), colloidal or semi-colloidal gra hite and preparations bsseEE gra hite in the form of astes, blocks, lates and other semi-manu actures (headmg 38.01). It also excyudes articles of naturigraphife (usualfy heading 68.15,69.02,69.03 or 85.45). P
Notes. 1.- Except where their context or Note 4 to this Chapter otherwise requires, the headings of this Chapter cover only products which are in the crude state or which have been washed (even with chemical substances eliminating the impurities without changing the structure of the product), crushed, ground, powdered, levigated, sifted, screened, concentrated by flotation, magnetic separation or other mechanical or physical processes (except crystallisation), but not products which have been roasted, calcined, obtained by mixing or subjected to processing beyond that mentioned in each heading. The products of this Chapter may contain an added anti-dusting agent, provided that such addition does not render the product particularly suitable for specific use rather than for general use. 2.- This Chapter does not cover : (a) Sublimed sulphur, precipitated sulphur or colloidal sulphur (heading 28.02); (b) Earth colours containing 70 % or more by weight of combined iron evaluated as Fe O 2 3 (heading 28.21); (c) Medicaments or other products of Chapter 30; (d) Perfumery, cosmetic or toilet preparations (Chapter 33); (e) Dolomite ramming mix (heading 38.16); (f) Setts, curbstones or flagstones (heading 68.01); mosaic cubes or the like (heading 68.02); roofing, facing or damp course slates (heading 68.03); (g) Precious or semi-precious stones (heading 71.02 or 71.03); (h) Cultured crystals (other than optical elements) weighing not less than 2.5 g each, of sodium chloride or of magnesium oxide, of heading 38.24; optical elements of sodium chloride or of magnesium oxide (heading 90.01); (ij) Billiard chalks (heading 95.04); or (k) Writing or drawing chalks or tailors' chalks (heading 96.09). 3.- Any products classifiable in heading 25.17 and any other heading of the Chapter are to be classified in heading 25.17. 4.- Heading 25.30 applies, inter alia, to : vermiculite, perlite and chlorites, unexpanded; earth colours, whether or not calcined or mixed together; natural micaceous iron oxides; meerschaum (whether or not in polished pieces); amber; agglomerated meerschaum and agglomerated amber, in plates, rods, sticks or similar forms, not worked after moulding; jet; strontianite (whether or not calcined), other than strontium oxide; broken pieces of pottery, brick or concrete.
