Products classified under HTS 7110.41.00.20
Unwrought Osmium Ingot
Pure osmium metal in the form of cast ingots, not having been subjected to any processes beyond melting and solidification. Classified under HTS 7110.41.00.20 as unwrought osmium, a platinum group metal in its basic raw form prior to further manufacturing.
Osmium Powder 99.9% Pure
Finely divided osmium metal powder where 90% or more passes through a 0.5 mm sieve, used in alloying and catalysis. Falls under HTS 7110.41.00.20 as osmium in powder form, explicitly defined in subheading notes for platinum group metals.
Cast Osmium Sponge
Porous osmium sponge produced by reduction processes, considered unwrought as it requires further refining before fabrication. HTS 7110.41.00.20 covers such basic forms of osmium, a dense platinum group metal used in alloys.
High-Purity Osmium Pellets
Small, pressed pellets of pure osmium used as starting material for evaporation and thin-film deposition. Classified as unwrought under HTS 7110.41.00.20 since no significant working beyond consolidation has occurred.
Electrolytic Osmium Cathodes
Cathode deposits of osmium from electrolytic refining, in plate form but still unwrought. HTS 7110.41.00.20 applies to such refined but unworked osmium metal.
