Products classified under HTS 3815.12.00.10
Platinum on Carbon Supported Catalyst
A high-surface-area activated carbon support impregnated with platinum nanoparticles, used primarily as a hydrogenation catalyst in organic synthesis. It falls under HTS 3815.12.0010 because the platinum group metal acts as the active substance on a solid support. Common in pharmaceutical and fine chemical production for reducing functional groups.
Palladium on Alumina Catalyst
Palladium nanoparticles dispersed on gamma-alumina support, essential for selective hydrogenations and coupling reactions like Heck and Suzuki. Classified in HTS 3815.12.0010 due to palladium (platinum group metal) as the active catalytic substance. Widely used in petrochemical refining and API synthesis.
Platinum-Rhenium on Alumina Reforming Catalyst
Bimetallic catalyst with platinum and rhenium on chlorinated alumina support for naphtha reforming in gasoline production. Falls under HTS 3815.12.0010 with platinum group metal (Pt) as primary active substance. Essential for petroleum refinery catalytic reformers.
Palladium on Barium Sulfate Catalyst
Rosenmund catalyst variant with Pd on BaSO4 support for selective hydrogenation of acid chlorides to aldehydes. Classified HTS 3815.12.0010 as supported palladium (PGM) preparation. Standard in organic synthesis laboratories and pharma production.
Platinum Black Supported on Alumina
High-activity platinum black (finely divided Pt metal) on porous alumina for ammonia oxidation in nitric acid plants. HTS 3815.12.0010 due to platinum as active substance on inorganic support. Used in Ostwald process for industrial fertilizer production.
Rhodium on Silica Supported Catalyst
Rhodium metal finely dispersed on silica gel or fumed silica carrier, used for hydroformylation and carbonylation processes. HTS 3815.12.0010 applies as rhodium (PGM) serves as the active substance in this supported preparation. Key in oxo-alcohol and acetic acid production.
Iridium Oxide on Carbon Catalyst
Iridium(IV) oxide nanoparticles supported on vulcan carbon black, used in polymer electrolyte membrane (PEM) fuel cells. HTS 3815.12.0010 classification based on iridium (PGM) compound as active substance. Critical for hydrogen oxidation in clean energy applications.
Ruthenium on Carbon Hydrogenation Catalyst
Ruthenium metal on activated carbon support for low-pressure hydrogenations of aromatic nitro compounds to amines. Falls under HTS 3815.12.0010 with Ru (PGM) as active catalytic substance. Preferred for aniline and pharmaceutical intermediate production.
