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.

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
heading No. 28.11.
5.- Headings Nos. 28.26 to 28.42 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 No. 28.42.
6.- Heading No. 28.44 applies only to :
(a) Technetium (atomic No.43), promethium (atomic No.61), polonium

(c) Compounds, inorganic or organic, of these elements or isotopes,
whether or not chemically defined, whether or not mixed together;

The term " isotopes ", for the purposes
of this Note and of the wording of headings Nos. 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.
