Current tariff classification

Notes.

1. Except where the context otherwise requires, the headings of this Chapter apply only to:
   1. Separate chemical elements and separate chemically defined compounds, whether or not containing impurities;
   2. The products mentioned in (a) above dissolved in water;
   3. 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;
   4. The products mentioned in (a), (b) or (c) above with an added stabiliser (including an anti-caking agent) necessary for their preservation or transport;
   5. 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.

4. Chemically defined complex acids consisting of a non-metal acid of sub-Chapter II and a metal acid of sub-Chapter IV are to be classified in 2811.
   
5. 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 2842.
6. 2844 applies only to:
   1. Technetium (atomic No. 43), promethium (atomic No. 61), polonium (atomic No. 84) and all elements with an atomic number greater than 84;
   2. 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;
   3. Compounds, inorganic or organic, of these elements or isotopes, whether or not chemically defined, whether or not mixed together;

   5. Spent (irradiated) fuel elements (cartridges) of nuclear reactors;
   6. Radioactive residues whether or not usable.

   "Isotopes", for the purposes of this Note and of the wording of 2844 and 2845, refers to:

   • - individual nuclides, excluding, however, those existing in nature in the monoisotopic state;
   • - 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. 2853 includes copper phosphide (phosphor copper) containing more than 15% 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 3818.00.00.
