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 28.11.
5. -
Headings 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 28.42.
6. -
Heading 28.44 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;

(irradiated) fuel elements (cartridges) of nuclear reactors;
(f) Radioactive
residues whether or not usable.
The term “isotopes”, for the purposes 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.
