Products classified under Tariff item 3815.19
Alumina-Supported Nickel Methanation Catalyst
Alumina-supported nickel methanation catalyst used in syngas processing to convert carbon monoxide and hydrogen into methane. The nickel active phase is dispersed on a high-surface-area alumina support, making it a supported catalyst preparation. It is classified under this tariff item as a supported catalyst not elsewhere specified or included.
3815.19.00Carbon-Supported Palladium Hydrogenation Catalyst
Carbon-supported palladium hydrogenation catalyst with 5% palladium on activated carbon, used for selective hydrogenation of nitro compounds to amines. The carbon support is not a specified support material in other subheadings, so this falls under the 'other' supported catalyst category. It is classified under this tariff item as a supported catalyst not elsewhere specified or included.
3815.19.00Ceria-Stabilized Alumina Three-Way Catalyst
Ceria-stabilized alumina three-way catalyst containing platinum, rhodium, and palladium on a complex oxide support, used in automotive catalytic converters to convert CO, hydrocarbons, and NOx. The multi-metal formulation and specialized support make it a complex supported catalyst preparation. It falls under this tariff item as a supported catalyst not elsewhere specified or included.
3815.19.00Magnesia-Supported Cobalt Fischer-Tropsch Catalyst
Magnesia-supported cobalt Fischer-Tropsch catalyst with 20% cobalt on magnesium oxide, used to convert syngas into synthetic hydrocarbons. The cobalt active phase on a magnesia support is a specific supported catalyst preparation. It is classified under this tariff item as a supported catalyst not elsewhere specified or included.
3815.19.00Silica-Supported Copper Dehydrogenation Catalyst
Silica-supported copper dehydrogenation catalyst with copper oxide on silica gel, used to accelerate dehydrogenation of alcohols to aldehydes in fine chemical production. The copper active phase on a silica support is not covered by other specific subheadings. It falls under this tariff item as a supported catalyst not elsewhere specified or included.
3815.19.00Titania-Supported Vanadium SCR Catalyst
Titania-supported vanadium SCR catalyst with V2O5/WO3 on anatase titania, used to reduce NOx emissions in selective catalytic reduction systems. The vanadium and tungsten oxides on a titania support form a specialized supported catalyst preparation. It is classified under this tariff item as a supported catalyst not elsewhere specified or included.
3815.19.00Zeolite-Supported Iron Ammonia Synthesis Catalyst
Zeolite-supported iron ammonia synthesis catalyst with promoted iron on a zeolite support, used in the Haber-Bosch process for ammonia production under high pressure and temperature. The iron active phase on a zeolite support is a specific supported catalyst preparation. It falls under this tariff item as a supported catalyst not elsewhere specified or included.
3815.19.00Zeolite-Supported Platinum Reforming Catalyst
Zeolite-supported platinum reforming catalyst used to facilitate hydrocarbon reforming reactions in petroleum refineries. The platinum active phase on a zeolite support is a supported catalyst preparation with precious metal content. It is classified under this tariff item as a supported catalyst not elsewhere specified or included, as the precious metal is not specified in other subheadings.
3815.19.00Zirconia-Supported Molybdenum Hydrodesulfurization Catalyst
Zirconia-supported molybdenum hydrodesulfurization catalyst with MoS2 on zirconia, used to remove sulfur from diesel fuel in hydrodesulfurization processes. The molybdenum sulfide active phase on a zirconia support is a complex supported catalyst preparation. It falls under this tariff item as a supported catalyst not elsewhere specified or included.
