  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 particulary 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. or c. above with an added anti-dusting agent or a colouring substance added to faciliate their identification or for safetly reasons, provided that the additions do not render the product particularly suitable for specific use rather than for general use.

  e. Spent (irradiated) fuel elements (cartridges) of nuclear reactors;
  f. Radioactive residues whether or not usable.
  The term "isotopes", for the purpose of this Note and of the wording of headings 28.44 and 28.45, 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. Heading 28.53 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 heading 38.18.
 
Subheading Note.
1. For the purposes of subheading 28.52.1000, the expression "chemically defined" means all organic or inorganic compounds of mercury meeting the requirements of paragraphs a. to e. of Note 1 to Chapter 28 or paragraphs a. to h. of Note 1 to Chapter 29.
