Names come in English where the EU Combined Nomenclature publishes them — chapters, headings and subheadings, whose first six digits are the same Harmonized System; deeper EAEU detail is a machine translation, marked as such. Official texts — tariff notes, measures, lists and classification rulings — are the original: customs and your broker go by that wording. Where we show a machine translation of them, it is marked; where our quality check rejected one, the Russian stays.

Cobalt is obtained mainly from ores containing heterogenite (hydrated cobalt oxide), linneite (cobalt and nickel sulfide) and schmaltite (cobalt arsenide). When melting
sulphide and arsenide ores, mattes and other intermediate products are obtained. After treatment to extract other metals, cobalt oxide is obtained, which is reduced with carbon, aluminium, etc. The metal is also extracted electrolytically and by treating residues from the refining of copper, nickel, silver, etc. Cobalt is a silvery, corrosion-resistant metal, harder than nickel, and has the greatest magnetic properties of the non-ferrous metals. Unalloyed cobalt is used for coating other metals (by electrodeposition), as a catalyst, as a binder in the manufacture of metal carbide cutting tools, as a component of cobalt-samarium magnets or of certain alloy steels, etc. There are many cobalt alloys; those which may fall in this heading by application of Note 5 to Section XV include: (1) The cobalt-chromium-tungsten group of alloys ("stellite") (often containing small quantities of other elements). Because of their high resistance to wear and to corrosion at high temperatures, they are often used in the manufacture of electronic valves and their bases, tools, etc. (2) Cobalt-iron-chromium alloys, e.g., grades with a low coefficient of thermal expansion, and a group of alloys having high ferromagnetic properties. (3) Cobalt-chromium-molybdenum alloys, used in jet engines. This heading covers cobalt mattes, other intermediate products of cobalt metallurgy and cobalt in all its forms, e.g., ingots, cathodes, granules, powders, waste and scrap, and articles thereof, not more specifically covered elsewhere.
