HS heading: 2827

Except where the context otherwise requires, the headings of this chapter apply only to:(

• a) separate chemical elements and separate chemically defined compounds, whether or not containing impurities;(
• b) the products mentioned in (a) above dissolved in water;(
• c) the products mentioned in (a) above dissolved in other solvents provided that the solution constitutes a normal and necessary method of putting up these products adopted solely for reasons of safety or for transport and that the solvent does not render the product particularly suitable for specific use rather than for general use;(
• d) the products mentioned in (a), (b) or (c) above with an added stabiliser (including an anti-caking agent) necessary for their preservation or transport;(
• e) the products mentioned in (a), (b), (c) or (d) above with an added anti-dusting agent or a colouring substance added to facilitate their identification or for safety reasons, provided that the additions do not render the product particularly suitable for specific use rather than for general use.

In addition to dithionites and sulphoxylates, stabilised with organic substances (heading 2831), carbonates and peroxocarbonates of inorganic bases (heading 2836), cyanides, cyanide oxides and complex cyanides of inorganic bases (heading 2837), fulminates, cyanates and thiocyanates, of inorganic bases (heading 2842), organic products included in headings 2843 to 2846 and 2852 and carbides (heading 2849), only the following compounds of carbon are to be classified in this chapter:(

• a) oxides of carbon, hydrogen cyanide and fulminic, isocyanic, thiocyanic and other simple or complex cyanogen acids (heading 2811);(
• b) halide oxides of carbon (heading 2812);(
• c) carbon disulphide (heading 2813);(
• d) thiocarbonates, selenocarbonates, tellurocarbonates, selenocyanates, tellurocyanates, tetrathiocyanatodiamminochromates (reineckates) and other complex cyanates, of inorganic bases (heading 2842);(
• e) hydrogen peroxide, solidified with urea (heading 2847), carbon oxysulphide, thiocarbonyl halides, cyanogen, cyanogen halides and cyanamide and its metal derivatives (heading 2853) other than calcium cyanamide, whether or not pure (Chapter 31).

Subject to the provisions of note 1 to Section VI, this chapter does not cover:(

• a) sodium chloride or magnesium oxide, whether or not pure, or other products of Section V;(
• b) organo-inorganic compounds other than those mentioned in note 2 above;(
• c) products mentioned in note 2, 3, 4 or 5 to Chapter 31;(
• d) inorganic products of a kind used as luminophores, of heading 3206; glass frit and other glass in the form of powder, granules or flakes, of heading 3207;(
• e) artificial graphite (heading 3801); products put up as charges for fire-extinguishers or put up in fire-extinguishing grenades, of heading 3813; ink removers put up in packings for retail sale, of heading 3824; cultured crystals (other than optical elements) weighing not less than 2,5 g each, of the halides of the alkali or alkaline-earth metals, of heading 3824;(
• f) precious or semi-precious stones (natural, synthetic or reconstructed) or dust or powder of such stones (headings 7102 to 7105), or precious metals or precious-metal alloys of Chapter 71;(
• g) the metals, whether or not pure, metal alloys or cermets, including sintered metal carbides (metal carbides sintered with a metal), of Section XV; or(
• h) optical elements, for example, of the halides of the alkali or alkaline-earth metals (heading 9001).
