Products classified under HTS 7110.41.00.30
Unwrought Ruthenium Bar
A solid bar of pure ruthenium metal in unwrought form, produced through electrolysis or chemical precipitation, weighing over 1 kg. It falls under HTS 7110.41.00.30 as unwrought ruthenium, not further processed into sheets, strips, or powder, used primarily as raw material for alloys in electronics and catalysis. This classification applies per Chapter 71 notes defining platinum group metals including ruthenium.
Ruthenium Sponge
Porous ruthenium sponge obtained from reduction processes, in unwrought lump form ready for melting into ingots. Classified under HTS 7110.41.00.30 as unwrought ruthenium, distinct from powder due to not meeting the 0.5mm sieve test in subheading notes. Commonly used in producing ruthenium catalysts for chemical industry.
Electrolytic Ruthenium Ingot
High-purity ruthenium ingot cast from electrolytic deposition, in unwrought rectangular form for remelting. Fits HTS 7110.41.00.30 as unwrought ruthenium per Chapter 71 definitions excluding semimanufactured states. Essential for plating solutions in hard disk drive manufacturing.
Ruthenium Pellet
Small cylindrical pellets of pure ruthenium produced by atomization but remaining unwrought, used for alloy addition in metallurgy. Classified in HTS 7110.41.00.30 as unwrought ruthenium, not qualifying as powder per sieve definition in subheading notes. Applied in titanium alloy production for aerospace.
Vacuum-Distilled Ruthenium Lump
Irregular lumps of ultra-pure ruthenium purified by vacuum distillation, in unwrought condition for research applications. Under HTS 7110.41.00.30 as unwrought ruthenium per platinum group definitions in Chapter notes. Used in scientific catalysis and thin-film deposition.
Ruthenium Grain
Granular unwrought ruthenium grains from hydrogen reduction, larger than powder specifications, for dosed alloying. HTS 7110.41.00.30 classification as unwrought ruthenium excludes powder form per subheading note sieve test. Ideal for jewelry alloying and electrical contacts.
