CHAPTER 26
Ores, slag and ash

Notes:

l. This Chapter doesn't cover:
 

(a) Slag or similar industrial waste prepared as macadam (heading No. 2517);

(b) Natural magnesium carbonate (magnesite) whether or not calcined (heading No. 2519);

(c) Sludges from the storage tanks of petroleum oils, consisting mainly of such oils (2710);

(d) Basic slag of Chapter 31;

(e) Slag wool, rock wool or similar mineral wools (heading No. 6806);

(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 No. 7112); or

(g) Copper, nickel or cobalt mattes produced by any process of smelting (Section XV).

2. For the purposes of heading Nos. 2601 to 2617, the term "ores" means minerals of mineralogical species actually used in the metallurgical industry for the extraction of mercury, of the metals of heading No. 2844 or of the metals of Section XIV or XV, even if they are intended for non-metallurgical purposes. Heading Nos. 2601 to 2617 do not, however, include minerals which have been submitted to processes not normal to the metallurgical industry.

3. Heading No. 2620 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 (heading2621); 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.

Sub Heading Notes :

1.    For the purposes of sub-heading 2620 21, "leaded gasoline sludges and leaded antiknock compound sludges" mean sludges obtained from storage tanks of leaded gasoline and leaded anti-knock compounds (for example, tetraethyle 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 sub-heading 2620 60.
