Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in powder form rather than sponge
Subheading differentiates unwrought/powder platinum sponge (0020) from powder (0030) based on sieve test in notes.
If silver predominates in alloy composition
Chapter Note 5(c) treats alloys with ≥2% silver (no platinum dominance) as silver alloys under Chapter 71.
If containing significant precious metal compounds pre-reduction
Precious metal compounds/ores classified in 2616 before reduction to metallic sponge form.

Import Tips & Compliance
• Submit third-party assay reports confirming >98% platinum to distinguish from base metal alloys
• Avoid packaging as retail sets, which could trigger classification under heading 7114 as goldsmiths' wares
• Document production process to prove sponge morphology vs. powder form misclassification

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.
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.
