(b)

(1) For samarium-cobalt magnets and neodymium iron-boron magnets, this restriction includes—

(i) Melting samarium with cobalt to produce the samarium-cobalt alloy or melting neodymium with iron and boron to produce the neodymium-iron-boron alloy; and

(ii) All subsequent phases of production of the magnets, such as powder formation, pressing, sintering or bonding, and magnetization.

(2) The restriction on melting and producing of samarium-cobalt magnets is in addition to any applicable restrictions on melting of specialty metals at 225.7003 and the clause at 252.225-7009, Restriction on Acquisition of Certain Articles Containing Specialty Metals.

(c) For production of tantalum metal and alloys, this restriction includes the reduction of tantalum chemicals such as oxides, chlorides, or potassium salts, to metal powder and all subsequent phases of production of tantalum metal and alloys, such as consolidation of metal powders.

(d) For production of tungsten metal powder and tungsten heavy alloy, this restriction includes—

(1) Atomization;

(2) Calcination and reduction into powder;

(3) Final consolidation of non-melt derived metal powders; and

(4) All subsequent phases of production of tungsten metal powder, tungsten heavy alloy, or any finished or semi-finished component containing tungsten heavy alloy.
