Products classified under HTS 7110.11.00.20
Platinum Sponge Catalyst Precursor
Porous platinum sponge used as a precursor material in the production of heterogeneous catalysts for chemical reactions like hydrogenation. Classified under HTS 7110.11.00.20 as unwrought platinum in sponge form, which is a semi-manufactured state prior to powdering or further processing. It meets the chapter definition of platinum (including alloys with predominant platinum content) in unwrought form.
High-Purity Platinum Sponge 99.99%
Ultra-pure platinum sponge (99.99% Pt) produced by precipitation and reduction, supplied in bulk for laboratory and jewelry fabrication. Falls under HTS 7110.11.00.20 as unwrought platinum sponge, a porous semi-manufactured form not qualifying as powder per subheading notes. Excludes clad or plated materials per Chapter Note 7.
Platinum Black Sponge Precursor
Spongy platinum precursor for platinum black catalysts used in fuel cells and organic synthesis. HTS 7110.11.00.20 covers this unwrought sponge form of platinum, distinct from final powder catalysts. Complies with definitions excluding iridium-group metals unless alloyed per Note 2(b).
Industrial Platinum Sponge for Wire Drawing
Porous platinum sponge melted down for thermocouple wire and lab ware production. Specifically under HTS 7110.11.00.20 as unwrought platinum sponge, a standard semi-manufactured input for precious metal fabrication. Meets unwrought criteria excluding finished shapes or powder.
Laboratory Grade Platinum Sponge
High-surface-area platinum sponge for analytical chemistry reductions and hydrogen absorption studies. Classified HTS 7110.11.00.20 as unwrought platinum in sponge form, suitable for lab-scale catalyst preparation. Distinguished from powder by particle morphology per subheading notes.
