Goods (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 export schedule. (b). Subject to paragraph (a) above, goods answering to a description in heading 2843 or 2846 are to be classified in those headings and in no other heading of this section. 2. Subject to note 1 above, goods 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 export schedule. 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 to be used together without first being repacked; (b). Exported together; and (c). Identifiable, whether by their nature or by the relative proportions in which they are present, as being complementary one to another. 4. For the purpose of the export schedule: (a). The term "aromatic" as applied to any chemical compound refers to such compound containing one or more fused or unfused benzene rings. (b). The term "modified aromatic" describes a molecular structure having at least one six-membered heterocyclic ring which contains at least four carbon atoms and having an arrangement of molecular bonds as in the benzene ring or in the quinone ring, but does not include any such molecular structure in which one or more pyrimidine rings are the only modified aromatic rings present. (c). For the purpose of headings 2902, 2907 and 3817, the term "alkyl" describes any saturated acyclic hydrocarbon group having six or more carbon atoms or, subject to note 1 to chapter 29, any mixtures of such groups averaging six or more carbon atoms. Notes 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). 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 a specific use rather than for general use; (d). The products mentioned in (a), (b) or (c) above with an added stabilizer (including an anticaking agent) necessary for their preservation or transport; (e). The products mentioned in (a), (b), (c) or (d) above with an added antidusting agent or a coloring substance added to facilitate their identification or for safety reasons, provided that the additions do not render the product particularly suitable for a specific use rather than for general use. 2.

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). 4. Chemically defined complex acids consisting of a nonmetal acid of sub-chapter II and a metallic acid of sub-chapter IV are to be classified in heading 2811. 5. Headings 2826 to 2842 apply only to metal or ammonium salts or peroxysalts. Except where the context otherwise requires, double or complex salts are to be classified in heading 2842. 6. Heading 2844 applies only to: (a). Technetium (atomic No. 43), promethium (atomic No. 61), polonium (atomic No. 84) and all elements with an atomic number greater than 84; (b). Natural or artificial radioactive isotopes (including those of the precious metals or of the base metals of sections XIV and XV), whether or not mixed together; (c). Compounds, inorganic or organic, of these elements or isotopes, whether or not chemically defined, whether or not mixed together; (d). Alloys, dispersions (including cermets), ceramic products and mixtures containing these elements or isotopes or inorganic or organic compounds thereof and having a specific radioactivity exceeding 74 becquerels per gram (0.002 microcurie per gram); (e). Spent (irradiated) fuel elements (cartridges) of nuclear reactors; (f). Radioactive residues whether or not usable. The term "isotope", for the purposes of this note and of the wording of headings 2844 and 2845, refers to: (i). individual nuclides, excluding, however, those existing in nature in the monoisotopic state; (ii). mixtures of isotopes of one and the same element, enriched in one or several of the said isotopes, that is, elements of which the natural isotopic composition has been artificially modified. 7. Heading 2848 includes copper phosphide (phosphor copper) containing more than 15 percent by weight of phosphorus. 8. Chemical elements (for example, silicon and selenium) doped for use in electronics are to be classified in this chapter, provided that they are in forms unworked as drawn, or in the form of cylinders or rods. When cut in the form of discs, wafers or similar forms, they fall in heading 3818. I.
