(g) 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 (9001).
 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:
 (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 Bq/g (0.002 microcurie/g);
 (e) Spent (irradiated) fuel elements (cartridges) of nuclear reactors;
 (f) 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.

Subheading Note.
 1.‑ For the purposes of 2852.10, "chemically defined" means all organic or inorganic compounds of mercury meeting the requirements of paragraph (a), (b), (c), (d) or (e) of Note 1 to this Chapter or paragraph (a), (b), (c), (d), (e), (f), (g) or (h) of Note 1 to Chapter 29.

Additional Note.
 1.‑ Notwithstanding Note 1 to this Chapter, the following products are classified in this Chapter even when they are not separate chemical elements nor separate chemically defined compounds:
 (a) Colloidal sulphur (2802.00.00);
 (b) Carbon blacks (2803.00.00);
 (c) Oleum (2807.00.00);
 (d) Sulphonitric acids (2808.00.00);
 (e) Polyphosphoric acids (2809);
 (f) Phosphorus trisulphide (2813);
