Chapter notes
CHAPTER 26
ORES, SLAG AND ASH
1. This Chapter does not cover:
(a) Slag or similar industrial waste prepared as
macadam (heading 25.17);
(b) Natural magnesium carbonate (magnesite),
whether or not calcined (heading 25.19);
(c) Sludges from the storage tanks of petroleum
oils, consisting mainly of such oils (heading
27.10);
(d) Basic slag of Chapter 31;
(e) Slag wool, rock wool or similar mineral
wools (heading 68.06);
(f) Waste or scrap of precious metal or of metal
clad with precious metal; other waste or scrap
containing precious metal or precious metal
compounds, of a kind used principally for the
recovery of precious metal (heading 71.12); or
(g) Copper, nickel or cobalt mattes produced by any
process of smelting (Section XV).
2. For the purposes of headings 26.01 to 26.17, the
term "ores" means minerals of mineralogical species
actually used in the metallurgical industry for the
extraction of mercury, of the metals of heading
28.44 or of the metals of Section XIV or XV, even if
they are intended for non metallurgical purposes.
Headings 26.01 to 26.17 do not, however, include
minerals which have been submitted to processes not
normal to the metallurgical industry.
3. Heading 26.20 applies only to:
(a) Slag, ash and residues of a kind used in
industry either for the extraction of metals or
as a basis for the manufacture of chemical
compounds of metals, excluding ash and residues
from the incineration of municipal waste
(heading 26.21); and
(b) Slag, ash and residues containing arsenic,
whether or not containing metals, of a kind
used either for the extraction of arsenic or
metals or for the manufacture of their chemical
compounds.
Subheading Notes.
1. For the purposes of subheading 2620.21.00, "leaded
gasoline sludges and leaded anti-knock compound
sludges" mean sludges obtained from storage tanks of
leaded gasoline and leaded anti-knock compounds (for
example, tetraethyl lead), and consisting
essentially of lead, lead compounds and iron oxide.
2. Slag, ash and residues containing arsenic, mercury,
thallium or their mixtures, of a kind used for the
extraction of arsenic or those metals or for the
manufacture of their chemical compounds, are to be
classified in subheading 2620.60.00.
