Deuterium und andere Deuteriumverbindungen; Wasserstoff und seine Verbindungen, mit Deuterium angereichert; Mischungen und Lösungen, die diese Erzeugnisse enthalten

1. 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. 2. 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 (headings 2837 to 2842), and other inorganic compounds, this chapter covers: fulminates, cyanates and thiocyanates, of inorganic bases; organic compounds of headings 2843 to 2846 and 2852; and hydrogen peroxide solidified with urea (heading 2847). 3. 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 heading 3824.

1. (A) Products (other than radioactive ores) answering to a description in heading 2844 or 2845 are to be classified in those headings and in no other heading of the Nomenclature. (B) Subject to paragraph (A) above, products answering to a description in heading 2843, 2846 or 2852 are to be classified in those headings and in no other heading of this Section. 2. Subject to Note 1 above, products classifiable in heading 3004, 3005, 3006, 3212, 3303, 3304, 3305, 3306, 3307, 3506, 3707 or 3808 by reason of being put up in measured doses or for retail sale are to be classified in those headings and in no other heading of the Nomenclature. 3. Goods put up in sets consisting of two or more separate constituents, some or all of which fall in this Section and are intended to be mixed together to obtain a product of Section VI or VII, are to be classified in the heading appropriate to that product, provided that the constituents are: (a) having regard to the manner in which they are put up, clearly identifiable as being intended for use together without first being repacked; (b) presented together; and (c) identifiable, whether by their nature or by the relative proportions in which they are present, as being complementary one to another.
